Description
Oilfield Cup Tester for BOP Stack and Wellhead Pressure Testing
SGPE Cup Tester helps drilling crews test the pressure integrity of BOP stacks, wellheads, casing heads, and well control equipment at the rig site. The tool connects to the drill string and runs into the casing below the wellhead. After the crew fills the test line with water, the rubber cup seals against the casing ID and allows pressure to build from the surface.
This field-proven test method helps operators check critical pressure-control equipment before drilling ahead, starting a workover job, or carrying out well servicing operations. It reduces setup time, saves rig time, and supports safer well control decisions in oil and gas field operations.
SGPE supplies Cup Tester assemblies for common petroleum casing sizes from 5 in to 20 in. Selected models support rated pressure up to 70 MPa, approximately 10,000 psi. For high-pressure applications, SGPE also provides reinforced rubber cup options for selected casing sizes and casing weight ranges, with special designs available up to 15,000 psi.

What Is a Cup Tester?
A Cup Tester is a drill-string pressure testing tool for oil and gas wells. Crews use it to check whether the BOP stack, wellhead, casing head, valves, and related pressure-control equipment can hold the required test pressure.
The tool runs below the wellhead through the drill string. Its rubber cup seals inside the casing and creates a temporary pressure barrier. Then the test pump applies pressure from the surface through a water-filled test line.
Because the tool uses a simple running process, drilling contractors, well control teams, and oilfield service companies often choose it for rig-site pressure checks, BOP test work, wellhead testing, casing head verification, and routine pressure-control equipment inspection.
Main Oilfield Applications
SGPE Cup Tester fits many petroleum field pressure test jobs. Drilling crews use it for BOP stack pressure testing on drilling rigs, oil and gas wellhead pressure testing, casing head pressure testing, and well control equipment checks.
The tool also helps crews complete pressure integrity testing before drilling ahead. During workover and well servicing operations, it supports faster pressure verification and reduces unnecessary setup work.
Operators can also use the Cup Tester for surface casing and intermediate casing test support. It can assist during pre-spud checks, drilling preparation, completion operations, maintenance work, and pressure-control equipment inspection.
These applications make the Cup Tester a practical choice for drilling contractors, wellhead service companies, workover crews, oilfield rental companies, well control service providers, and petroleum equipment distributors.
Why Choose SGPE Cup Tester?
SGPE designs Cup Tester assemblies for real oilfield working conditions. Each model focuses on sealing performance, easy rig-site operation, suitable connection options, and stable pressure performance.
Fast Rig-Site Pressure Testing
The crew connects the Cup Tester to the drill string, lowers it into the casing, fills the test line with water, and starts the pressure test from the surface. This process helps reduce downtime during BOP, wellhead, and casing head test operations.
Reliable Rubber Cup Seal
The rubber cup seals against the casing inner wall and creates a stable test barrier. This design helps crews complete pressure integrity checks with fewer steps and clearer test results.
Wide Casing Size Range
SGPE offers Cup Tester models for common oilfield casing sizes, including 5 in, 5 1/2 in, 7 in, 9 5/8 in, 10 3/4 in, 13 3/8 in, and 20 in casing.
This size range helps customers match the correct Cup Tester to different drilling, workover, and well servicing programs. It also supports common petroleum casing applications, from smaller casing pressure tests to large surface casing and wellhead test operations.
High-Pressure Options
Selected SGPE Cup Tester models support rated pressure up to 70 MPa, approximately 10,000 psi. For demanding high-pressure jobs, SGPE can recommend reinforced rubber cups for selected casing sizes and casing weight ranges up to 15,000 psi.
Common Drill-String Connections
SGPE Cup Testers come with common oilfield connections, including NC26, NC31, NC38, and NC50. These connection options help the tool fit standard drilling assemblies and rig equipment.
Custom Support for Special Casing Programs
Different wells may require different cup sizes, pressure ratings, or connection options. SGPE can review your casing data and recommend a suitable standard or reinforced Cup Tester configuration.
How the Cup Tester Works
The Cup Tester uses a simple, field-proven process.
First, the crew connects the tool to the drill string. Then they lower it into the casing below the wellhead. Once the tool reaches the planned depth, the operator fills the hookup and test line with water.
Next, the rubber cup seals against the casing ID. The test pump applies pressure from the surface, and the tool helps isolate the test section. The crew can then check whether the BOP stack, wellhead, casing head, valves, and related equipment can hold the required pressure.
This method gives drilling and workover teams a practical way to confirm pressure integrity before key well operations.
Product Features
SGPE Cup Tester connects directly to the drill string and runs into the casing below the wellhead. The rubber cup seals against the casing ID and creates a reliable pressure test barrier for BOP stack, wellhead, casing head, and well control equipment checks.
