Description
Drill Cuttings Screw Conveyor for Oilfield Solids Control and Waste Handling Systems
SGPE manufactures Drill Cuttings Screw Conveyors for collecting, transferring and controlling drilled solids in oil and gas drilling operations.
Also known as an Oilfield Screw Conveyor, Drill Cuttings Conveyor, Drilling Waste Screw Conveyor, Oilfield Auger Conveyor, Drill Cuttings Auger or Shale Shaker Cuttings Conveyor, the equipment creates a controlled transfer route between solids control equipment and downstream drilling waste treatment.
On a typical drilling rig, the conveyor is installed below or beside one or several shale shakers. The rotating auger receives wet cuttings from the shaker discharge and moves them toward a Vertical Cuttings Dryer, High-G Drying Shaker, drilling waste tank, cuttings box, offshore cuttings skip or other secondary treatment equipment.
SGPE configures the screw diameter, conveyor length, screw pitch, operating speed, feed points, discharge location, installation angle, motor, gearbox, VFD, support structure and electrical system around the actual rig layout.
The equipment suits land rigs, offshore platforms, jack-up rigs and semi-submersible drilling units. It can handle WBM, OBM and SBM cuttings and integrate into multi-shaker solids control packages, pitless drilling systems, closed-loop drilling waste systems and complete drill cuttings handling packages.

Oilfield Screw Conveyor for Drill Cuttings and Drilled Solids
Drill cuttings do not behave like ordinary dry bulk material.
After a shale shaker separates coarse solids from circulating drilling fluid, the discharged waste can still contain water, base oil, synthetic drilling fluid, barite, clay, sand and formation particles.
The material may therefore be wet, sticky, heavy and abrasive. Particle size, bulk density and retained fluid content can also change as drilling moves through different formations and hole sections.
A general industrial auger may struggle with these conditions. An oilfield screw conveyor for drilling waste needs sufficient torque, structural strength and wear resistance for continuous drilled-solids service.
Inside the trough, the rotating screw advances the cuttings toward the discharge point. Covers help contain wet material and reduce mud splash around the shaker area.
When several shale shakers operate together, multiple feed openings can direct their discharge into one common conveyor. This creates a compact drill cuttings transfer system and reduces the number of separate material-handling points on the rig.
Drill Cuttings Screw Conveyor Manufacturer & Custom Engineering
SGPE supplies screw conveyors around the actual drilling process rather than limiting customers to one fixed catalog configuration.
A project may use one shale shaker or a complete shaker bank. It may handle sticky WBM cuttings, fluid-rich OBM waste or SBM cuttings that require controlled feeding into a Vertical Cuttings Dryer.
Transfer distance, feed elevation, discharge height and installation angle also vary from rig to rig. Offshore installations add further considerations such as deck space, lifting access, corrosion protection and hazardous-area electrical requirements.
A custom Drill Cuttings Screw Conveyor can therefore include project-specific screw diameter, conveyor length, inlet positions, discharge arrangement, drive power, gearbox, VFD, control mode and structural supports.
Customers can send a technical datasheet, rig layout, GA drawing or basic operating information for engineering review and quotation.

Common Screw Diameter and Conveyor Length Options
Screw diameter provides a useful starting point, but the final selection must also match the required throughput, cuttings properties and installation layout.
| Nominal Diameter | Approx. Metric Size | Common Length Options | Typical Selection |
|---|---|---|---|
| 10 in | 250 mm | 24 / 36 / 48 ft | Compact layout or lower solids load |
| 12 in | 300–315 mm | 24 / 36 / 48 ft | Single-shaker or moderate waste transfer |
| 14 in | 350–356 mm | 24 / 36 / 48 ft | Multi-shaker collection and dryer feeding |
| 16 in | Approx. 400–406 mm | Project-Specific | Higher drilling waste volume |
| 18 in | Approx. 450 mm | Project-Specific | Larger drilling waste systems |
Typical conveyor lengths include approximately 24, 36 and 48 ft, or about 7.3, 11 and 14.6 m.
Shorter or customized lengths can suit compact rigs, offshore installations and direct equipment-to-equipment transfer. Modular construction can simplify transportation, lifting and field installation.
A larger screw is not automatically the better choice. Diameter, length, speed, filling ratio and motor power need to work together with the actual solids load and transfer route.
Typical Applications on Drilling Rigs
A Drill Cuttings Screw Conveyor can perform several functions within a solids control and drilling waste management system.
| Application | Typical Function | Typical Destination |
|---|---|---|
| Shale Shaker Cuttings Collection | Collects wet drilled solids from shaker discharge | Dryer / Tank / Box / Skip |

| Zero-Discharge System | Supports controlled solids transfer within the overall system | Treatment / Collection Equipment |
Screw Conveyor for WBM, OBM and SBM Drill Cuttings
Different drilling fluid systems produce different waste characteristics, so conveyor selection should follow the actual mud system.
Water-Based Mud Cuttings
WBM cuttings often contain water, clay, sand and formation solids. Reactive formations can create sticky material that does not flow like ordinary dry solids.
A WBM Drill Cuttings Conveyor can transfer this waste from the shale shaker toward a High-G Drying Shaker, cuttings box, waste tank, pitless treatment system or central collection area.
Moisture content, particle size, consistency, required throughput and transfer distance are important selection factors.
Oil-Based Mud Cuttings
OBM cuttings often retain valuable drilling fluid after primary shaker separation.
An OBM Cuttings Conveyor commonly transfers the wet material toward a Vertical Cuttings Dryer. Stable feed helps the downstream dryer handle the cuttings more consistently.
Selection should consider OBM density, retained fluid content, required capacity, number of shale shakers, conveyor length, installation angle and dryer capacity.
Synthetic-Based Mud Cuttings
SBM cuttings normally follow a treatment route similar to OBM waste.
An SBM Cuttings Conveyor can collect wet solids from the shale shaker discharge and feed a Vertical Cuttings Dryer or dedicated collection system.
Where the incoming cuttings rate changes frequently, VFD control provides useful feed adjustment.
How Does a Drill Cuttings Screw Conveyor Work?
An electric motor drives the gearbox, which transfers torque to the screw shaft.
As the helical auger rotates inside the trough, the flights push drilled solids toward the discharge end.
One or several shale shakers can feed the same conveyor. From there, the cuttings move toward downstream treatment or collection equipment.
When drilling conditions change, a VFD can adjust screw speed. This is useful when ROP increases, hole size changes, another shale shaker comes online or downstream equipment begins to receive a heavier solids load.
The conveyor therefore acts as both a drilling waste transfer unit and a controlled feed interface between solids control and downstream treatment equipment.
Shale Shaker Discharge and Multi-Shaker Cuttings Collection
A Shale Shaker Discharge Screw Conveyor normally sits below or beside the shaker discharge and collects coarse drilled solids after primary mud separation.
On rigs with several shale shakers, one long conveyor can run along the complete shaker bank. Multiple feed openings allow each shaker to discharge into the same auger.
A typical arrangement follows:
Shale Shaker 1 + Shale Shaker 2 + Shale Shaker 3 → Common Screw Conveyor → Central Waste Treatment
This arrangement suits high-flow solids control systems, high-ROP drilling, larger hole sections and rigs that need one centralized drill cuttings handling system.
The final discharge can feed a Vertical Cuttings Dryer, High-G Drying Shaker, waste tank, cuttings box or offshore skip.
Cuttings Dryer Feed Conveyor and High-G Shaker Feeding
Vertical Cuttings Dryer Feed Conveyor
A Vertical Cuttings Dryer Feed Conveyor is commonly used in OBM and SBM drilling waste recovery systems.
After the shale shaker removes coarse solids, the discharged cuttings can still retain drilling fluid. The screw conveyor collects these wet solids and feeds them toward the dryer at a controlled rate.
A typical process follows:
Wellbore → Shale Shaker → Drill Cuttings Screw Conveyor → Vertical Cuttings Dryer → Decanter Centrifuge → Recovered Drilling Fluid
VFD control can help operators adjust the incoming feed when the cuttings volume changes.
High-G Drying Shaker Feed Conveyor
For many WBM systems, the screw conveyor can feed a High-G Drying Shaker instead.
A typical route follows:
Primary Shale Shaker → Screw Conveyor → High-G Drying Shaker → Cuttings Collection
This arrangement provides additional liquid removal before the solids move into storage, transport or further treatment.
Cuttings Box, Waste Tank and Offshore Skip Loading
Not every drilling waste system requires a dedicated dryer.
A Cuttings Box Loading Conveyor can transfer raw or treated waste directly from the solids control area into a collection box. The same conveyor can feed a drilling waste tank or offshore cuttings skip.
The discharge chute can be positioned around the actual container location, loading height and available rig space.
For offshore projects, the discharge arrangement can also be coordinated with skip loading, deck access and lifting requirements.
Centrifuge Solids Screw Conveyor
Decanter centrifuges can discharge fine solids that require additional transport.
A Centrifuge Solids Screw Conveyor can move this material toward a waste tank, cuttings box, offshore skip or dedicated disposal container.
Centrifuge solids normally follow a downstream collection route rather than returning to the standard Vertical Cuttings Dryer feed stream.
The discharge height, solids consistency and receiving equipment should therefore be reviewed separately from the primary shale shaker cuttings conveyor.
Onshore, Offshore and Hazardous-Area Configurations
Onshore Drill Cuttings Conveyor
Land rigs usually provide more installation space, but transfer distance, shale shaker arrangement, feed elevation and discharge height still affect conveyor selection.
An onshore system can collect shaker discharge, combine waste from several shakers, feed a dryer or move solids directly into a tank or box.
Offshore Drill Cuttings Screw Conveyor
An Offshore Drill Cuttings Screw Conveyor provides compact drilled-solids transportation where deck space is limited.
Typical applications include fixed offshore platforms, jack-up rigs, semi-submersible drilling units, offshore OBM/SBM treatment systems, Vertical Cuttings Dryer packages and cuttings skip loading.
Offshore projects may require marine corrosion protection, special coating systems, project-specific supports and electrical equipment suitable for the specified area classification.
Hazardous-Area Configuration
When the conveyor operates inside a classified area, the engineering review considers the required area classification together with the motor, enclosure, VFD arrangement, cable glands, local control station and emergency-stop system.
The final electrical configuration follows the project specification rather than one universal package.
Horizontal, Inclined and VFD Oilfield Screw Conveyor Options
Horizontal Screw Conveyor
Horizontal installation works well when shale shakers and downstream equipment are at similar elevations.
It also suits multi-shaker collection because one conveyor can run along the complete shaker line.
Since the auger does not need to raise the material significantly, horizontal operation generally provides better effective conveying performance than a steep inclined arrangement.
Inclined Drill Cuttings Screw Conveyor
An Inclined Drill Cuttings Screw Conveyor can raise solids toward a higher dryer, waste tank, cuttings box or collection platform.
As inclination increases, effective throughput normally falls and torque demand rises.
For proper selection, provide the horizontal transfer distance, feed elevation, discharge elevation, installation angle and required capacity.
VFD Drill Cuttings Screw Conveyor
A fixed-speed unit works well when solids loading remains relatively stable.
In practice, cuttings volume changes with ROP, hole diameter, formation conditions and the number of active shale shakers.
A VFD Drill Cuttings Screw Conveyor allows operators to adjust screw speed to match both incoming cuttings volume and downstream treatment capacity.
| Control Mode | Typical Application | Main Benefit |
|---|---|---|
| Fixed Speed | Stable solids loading | Simple operation |
| VFD Variable Speed | Changing ROP or waste volume | Adjustable feed rate |
| Forward / Reverse | Multiple discharge routes | Flexible material direction |
| Local Control | Standalone conveyor | Simple field operation |
| Remote Control | Integrated waste package | Centralized operation |
| System Interlock | Dryer or solids control package | Coordinated operation |
What Determines Drill Cuttings Screw Conveyor Capacity?
There is no single Drill Cuttings Screw Conveyor capacity that represents every installation.
Screw diameter affects the available conveying volume, while screw speed and pitch determine how quickly the material moves through the trough.
Bulk density, retained liquid and particle size influence the torque required to move the waste. Filling ratio also matters because a lightly loaded conveyor behaves differently from one operating at a higher fill level.
Conveyor length adds mechanical resistance, while an inclined installation generally provides less effective capacity than the same unit operating horizontally.
For accurate sizing, provide the required throughput in m³/h or t/h, together with the mud type, cuttings characteristics and actual installation layout.
Wear-Resistant Design, Safety and Maintenance
Drill cuttings can contain sand, rock fragments and abrasive formation solids. These materials continuously contact the screw flights and trough.
For demanding service, SGPE can review wear-resistant screw flights, increased flight thickness, hard-facing, reinforced trough areas and replaceable wear components.
The shaft, couplings and gearbox also need sufficient mechanical margin for the expected load.
Safety options can include removable trough covers, feed-area grating, drive guards, emergency stops, pull-wire or grab-line stops, motor overload protection and lockout provisions.
Routine inspection should cover the screw flights, shaft, bearings, couplings, gearbox, trough and discharge area.
Typical Drilling Waste Process Configurations
| System | Typical Process Flow |
|---|---|
| OBM / SBM Recovery | Shale Shaker → Screw Conveyor → Vertical Cuttings Dryer → Centrifuge |
| WBM Treatment | Shale Shaker → Screw Conveyor → High-G Drying Shaker → Collection |
| Multi-Shaker Collection | Multiple Shakers → Common Screw Conveyor → Central Treatment |
| Direct Waste Collection | Shale Shaker → Screw Conveyor → Box / Tank / Skip |
| Offshore Skip Loading | Shale Shaker → Screw Conveyor → Offshore Cuttings Skip |
| Centrifuge Solids Transfer | Decanter Centrifuge → Screw Conveyor → Waste Collection |
| Pitless Drilling | Shale Shaker → Screw Conveyor → Enclosed Treatment / Collection |
| Closed-Loop System | Solids Control → Screw Conveyor → Recovery / Collection Equipment |
These are common process routes. The final system should follow the actual mud program, drilling rig arrangement and waste management plan.
Drill Cuttings Screw Conveyor Selection Guide
Correct selection starts with the material and process layout rather than the screw diameter alone.
| Selection Data | Why It Matters |
|---|---|
| WBM / OBM / SBM | Defines waste characteristics |
| Required Capacity | Determines conveyor size |
| Bulk Density | Influences drive torque |
| Fluid Content | Influences sticking and material weight |
| Maximum Particle Size | Affects screw clearance |
| Screw Diameter | Influences conveying volume |
| Screw Pitch | Influences material movement |
| Screw Speed | Influences throughput |
| Conveyor Length | Influences drive power |
| Installation Angle | Influences effective capacity |
| Number of Shale Shakers | Determines feed point quantity |

| VFD Requirement | Determines speed-control strategy |
| Hazardous Area | Determines electrical requirements |
| Onshore / Offshore | Influences structure and coating |
| Client Standard | Determines inspection and documentation |
This information allows the equipment to be matched to real operating conditions instead of simply selecting the largest available auger.
Custom Drill Cuttings Auger Conveyor
A standard conveyor cannot match every drilling rig.
SGPE can customize screw diameter, screw pitch, conveyor length, modular section length, feed point quantity, hopper dimensions and discharge chute arrangement.
The drive system can use project-specific motor power, gearbox ratio, VFD control and forward/reverse operation.
Customers can also specify local or remote control, support frames, skid arrangements, wear-resistant materials and coating requirements.
For offshore installations, engineering review can include the marine environment, deck layout, lifting requirements and equipment interfaces.
A rig GA drawing or installation sketch provides the best basis for customization.
Drill Cuttings Screw Conveyor Price & Quotation
The Drill Cuttings Screw Conveyor price depends on the actual project configuration rather than one standard catalog value.
The same applies to Oilfield Screw Conveyor price, Drilling Waste Conveyor cost and custom auger quotations.
| Price Factor | How It Affects the Quotation |
|---|---|
| Screw Diameter | Changes screw, trough and drive size |
| Conveyor Length | Changes fabrication scope and drive requirement |
| Required Capacity | Influences screw and gearbox selection |
| VFD Control | Adds variable-speed control equipment |
| Number of Feed Points | Changes inlet and trough arrangement |
| Installation Angle | Can change drive and support requirements |
| Wear Protection | Adds hard-facing or wear-resistant materials |
| Hazardous-Area Requirement | Changes electrical equipment |
| Offshore Service | Can require marine coating and structural upgrades |
| Custom Support Structure | Changes fabrication scope |
| Voltage / Frequency | Influences motor and control configuration |
| Inspection Scope | Can affect testing and documentation |
| Delivery Destination | Influences packing and freight quotation |
For an accurate quotation, send the actual operating conditions and rig layout instead of requesting a price based only on screw diameter.
Information Required for a Drill Cuttings Screw Conveyor RFQ
For accurate technical selection, provide the drilling fluid type, required conveying capacity, approximate bulk density, retained fluid content and maximum expected cuttings size.
Layout information should include conveyor length, horizontal transfer distance, feed elevation, discharge elevation and installation angle. If the project already specifies a screw diameter, include that value.
Please also provide the number of shale shakers, shaker discharge spacing, number of feed points and the upstream and downstream equipment.
For the electrical package, specify voltage, frequency, area classification and preferred control method. Also confirm whether the project requires fixed-speed operation, VFD control, remote operation or system interlocks.
Finally, identify whether the equipment will operate onshore or offshore. Ambient temperature, corrosion conditions, coating specification, inspection scope, client standard and delivery destination can also affect the final proposal.
A rig GA drawing or installation sketch can significantly improve technical selection.
Talk to SGPE About Your Drill Cuttings Handling System
Whether your project requires one Drill Cuttings Screw Conveyor, a custom Oilfield Auger Conveyor or a complete drill cuttings handling system, SGPE can configure the equipment around the actual drilling process.
For OBM and SBM recovery, a typical package can connect the shale shaker, screw conveyor, Vertical Cuttings Dryer and Decanter Centrifuge.
For WBM applications, the conveyor can feed a High-G Drying Shaker and downstream collection system.
A multi-shaker rig can use one common auger for centralized drilled-solids transportation, while simpler systems can discharge directly into a cuttings box, drilling waste tank or offshore skip.
These configurations suit land rigs, offshore rigs, jack-up rigs, WBM systems, OBM systems, SBM systems, pitless drilling and closed-loop drilling waste management.
Manufacturing, Testing and Project Documentation
For project orders, SGPE can prepare documentation according to the agreed purchase specification.
Depending on scope, the package can include a technical datasheet, General Arrangement drawing, equipment dimensions, motor and gearbox information, electrical data, material information, inspection records, no-load running test records and coating inspection records.
An operation and maintenance manual, packing list, project-specific ITP and additional quality documentation can also form part of the supply when required.
Third-party inspection can be coordinated according to the agreed project scope.
Why Choose SGPE for Drill Cuttings Conveying Equipment?
SGPE focuses on oil and gas drilling, solids control and drilling waste management equipment.
Instead of selecting an auger only from diameter and length, the engineering review considers the complete drilling waste transfer route.
This includes shale shaker arrangement, cuttings characteristics, required throughput, transfer distance, installation angle, feed elevation, discharge elevation and downstream treatment capacity.
For offshore or technically demanding projects, the review can also cover rig power supply, hazardous-area requirements, environmental conditions, equipment interfaces, inspection scope and project documentation.
This project-based approach helps match the conveyor with both upstream solids control equipment and downstream drilling waste treatment before manufacturing begins.
Frequently Asked Questions About Drill Cuttings Screw Conveyors
1. What is a Drill Cuttings Screw Conveyor?
A Drill Cuttings Screw Conveyor is an auger-type conveying system used to collect and transfer drilled solids within an oilfield solids control or drilling waste management system. It normally receives wet cuttings discharged from shale shakers and transports them toward downstream equipment such as a Vertical Cuttings Dryer, High-G Drying Shaker, drilling waste tank, cuttings box or offshore cuttings skip.
The equipment is also commonly referred to as an Oilfield Screw Conveyor, Drill Cuttings Conveyor, Drilling Waste Screw Conveyor, Oilfield Auger Conveyor or Shale Shaker Cuttings Conveyor. It provides a controlled transfer path for wet, sticky and abrasive drilling waste on both land and offshore drilling rigs.
2. Where is a Drill Cuttings Screw Conveyor installed on a drilling rig?
A Drill Cuttings Screw Conveyor is usually installed below or beside the shale shaker discharge in the solids control area. This position allows the auger to receive drilled solids immediately after primary separation and move them away from the shaker area without relying on repeated manual handling.
On a single-shaker rig, one feed point may be sufficient. On larger land rigs, offshore platforms, jack-up rigs or semi-submersible units, one longer Shale Shaker Discharge Conveyor can run along several shakers and combine their cuttings into one centralized transfer line. The final discharge can connect to a Vertical Cuttings Dryer, High-G Shaker, waste tank, cuttings box or offshore skip.
3. Can one screw conveyor collect cuttings from several shale shakers?
Yes. A Multi-Shaker Cuttings Conveyor can collect drilled solids from several shale shakers through multiple feed openings arranged along the conveyor trough. Each shaker discharges into the same auger, which combines the solids and transports them toward one central treatment or collection point.
This configuration is useful on drilling rigs with a complete shaker bank, especially during high-flow or high-ROP drilling operations where several shale shakers operate at the same time. The feed point spacing, conveyor length, screw diameter and discharge location should match the actual shaker arrangement and available rig space.
4. Can a Drill Cuttings Screw Conveyor handle WBM, OBM and SBM cuttings?
Yes. A Drill Cuttings Screw Conveyor can handle Water-Based Mud (WBM), Oil-Based Mud (OBM) and Synthetic-Based Mud (SBM) cuttings, but the conveyor should be selected according to the characteristics of each waste stream.
WBM cuttings can become clay-rich, wet and sticky, while OBM and SBM cuttings often retain more drilling fluid and may be heavier or more fluid-rich after shale shaker separation. For this reason, SGPE reviews factors such as bulk density, retained liquid content, particle size, required throughput, conveyor length, screw speed and installation angle before confirming the final configuration.
5. Can a Drill Cuttings Screw Conveyor feed a Vertical Cuttings Dryer?
Yes. A Vertical Cuttings Dryer Feed Conveyor is commonly used to transfer wet OBM and SBM cuttings from the shale shaker discharge toward a Vertical Cuttings Dryer.
A typical drilling waste recovery process is Shale Shaker → Drill Cuttings Screw Conveyor → Vertical Cuttings Dryer → Decanter Centrifuge. In this arrangement, the conveyor acts as both a transfer device and a controlled feeding interface between the shale shaker and dryer.
Where drilling waste volume changes frequently, VFD speed control can help operators adjust the screw speed so that the dryer receives a more stable feed instead of sudden changes in solids loading.
6. What screw diameter should I choose for a Drill Cuttings Screw Conveyor?
Common oilfield screw diameters are approximately 10 to 18 in, but the correct size depends on more than the nominal auger diameter.
Required throughput, bulk density, retained drilling fluid, maximum particle size, screw pitch, operating speed, conveyor length and installation angle all affect equipment selection. A larger screw can provide more conveying volume, but it also increases drive torque, motor power, equipment weight and overall dimensions.
For a reliable selection, the required capacity should preferably be provided in m³/h or t/h together with the actual drilling waste characteristics and rig layout.
7. What conveyor lengths are available for drilling rig applications?
Common reference lengths include approximately 24, 36 and 48 ft, equivalent to about 7.3, 11 and 14.6 m. Custom lengths can also be engineered to match the actual distance between shale shakers and downstream drilling waste equipment.
Shorter conveyors may suit compact solids control packages, while longer or modular units can serve multi-shaker lines, Vertical Cuttings Dryer packages and centralized waste transfer systems. On offshore rigs, modular construction can also simplify transportation, deck lifting and installation where access and available space are limited.
8. What capacity can a Drill Cuttings Screw Conveyor handle?
There is no single capacity that applies to every Drill Cuttings Screw Conveyor because actual throughput depends on the complete operating condition.
Screw diameter, screw speed, pitch and filling ratio determine the available conveying volume, while cuttings density, retained liquid and particle size influence the required torque. Conveyor length and installation angle also matter because longer or steeper conveyors generally create more resistance and may reduce effective throughput.
For accurate sizing, SGPE recommends providing the required capacity in m³/h or t/h, together with the drilling fluid type, approximate bulk density, cuttings consistency, conveyor length and installation angle.
9. How much does a Drill Cuttings Screw Conveyor cost?
The Drill Cuttings Screw Conveyor price depends on the actual project configuration rather than one standard catalog value.
Major cost factors include screw diameter, conveyor length, motor power, gearbox, VFD control, number of feed points, installation angle, wear protection and support structure. Offshore service may also require marine coating, customized structural supports and electrical equipment suitable for the specified area classification.
Inspection requirements, documentation scope, packing and delivery destination can also affect the final quotation. For this reason, SGPE prepares commercial offers according to the actual technical and installation requirements.
10. Can a Drill Cuttings Screw Conveyor operate at an incline and use VFD control?
Yes. An Inclined Drill Cuttings Screw Conveyor can raise drilled solids toward a higher Vertical Cuttings Dryer, waste tank, cuttings box or collection platform when the downstream equipment is installed above the shale shaker discharge level.
However, increasing the installation angle generally reduces effective conveying capacity and increases torque demand. The angle therefore needs to be considered together with screw diameter, conveyor length and required throughput.
VFD control is also available and allows operators to adjust screw speed when ROP, hole size, shaker quantity or downstream treatment capacity changes during drilling operations.
11. Can SGPE supply offshore and hazardous-area Drill Cuttings Screw Conveyors?
Yes. SGPE can configure Offshore Drill Cuttings Screw Conveyors for fixed platforms, jack-up rigs, semi-submersible units and offshore drilling waste treatment packages.
Depending on project requirements, the conveyor can include marine corrosion protection, project-specific coating systems, customized supports, VFD control and discharge arrangements for Vertical Cuttings Dryers, waste tanks or offshore cuttings skips.
For classified drilling areas, the final motor, control enclosure, cable glands, local control station and electrical package should follow the specified hazardous-area classification and project electrical standard rather than one universal configuration.
12. What information should I provide for a Drill Cuttings Screw Conveyor quotation?
For an accurate Drill Cuttings Screw Conveyor quotation, provide the drilling fluid type, required conveying capacity, approximate bulk density, retained fluid content, maximum expected particle size, conveyor length and installation angle.
The rig layout should also identify the number of shale shakers, shaker discharge spacing, feed and discharge elevations, upstream equipment and downstream equipment. Electrical information such as voltage, frequency, preferred control method and area classification is also important.
For offshore projects, installation environment, coating requirements and delivery destination should be included. A rig GA drawing, equipment layout or installation sketch can help SGPE confirm the screw diameter, drive system, VFD arrangement and structural configuration and prepare the corresponding technical proposal and commercial quotation.
Related Oilfield Solids Control Equipment
A Drilling Shale Shaker provides the primary solids separation stage and sends coarse drilled solids toward the conveyor.
A Vertical Cuttings Dryer can recover additional drilling fluid from wet OBM and SBM cuttings, while a Drilling Mud Decanter Centrifuge removes finer solids and treats recovered fluid.
A Mud Cleaner provides secondary solids separation through hydrocyclones and fine screens. For many WBM applications, a High-G Drying Shaker removes additional liquid before final waste collection.
These related products should be internally linked within the SGPE Solids Control and Drilling Waste Management product matrix.
