Proper thread engagement in upper 1/3 of collarThis connection would indicate a good make-up on the tong torque gauge.

STV SystemsResearch & Development

All connection Research & Development testing was performed in 5 R&D labs (Grant Prideco, Vam, Franks Casing, Offshore Energy Services, Eckel (Tong) Manufacturing and on working rigs in Texas and Louisiana.

Shoulder Thread Torque Verifier System

STV System Overview (1)

1. The System verifies the thread engagement & torque being applied to the complete length of the mating threads with-in the connection box.

2. The Verifier System detects a .012 degree C, Delta T, beneath each pixel through-out the verified connection.

3. The System verifies the torque applied to the drill pipe shoulder, shoulder seal and tool joint thread.

4. The System verifies break-out torque and can calculate life predictions on drill pipe connections.

5. Real time make-up is displayed on operator & rig monitors,

6. The system sounds alarm warning when real-time STV signature is outside of operator pre-set parameters.

STV System Overview (2)

7. The STV System stores all verified connections thread data for future use.

8. The System will utilize satellite communications for world-wide real-time operator monitoring, alarms and file downloading.

9. The System has real-time plot & signature verification capabilities of the made-up connection for visual comparison with archived files.

10. The System is portable and the STV System camera can be placed/mounted up to 50 -100 feet out of the immediate work area.

11. The System monitors can be mounted on the tong, drillers consol, in the dog house, and/or company man office.

12. The STV System is designed for oilfield onshore, offshore and bucking machine use.

5. The Connections will Not Be Larger Than 13 3/8” Diameter.

6. All Lab Testing Will Be Done At Stress Engineering.

7. STV will Provide Personnel, Cameras, and Computer Equipment to Perform Thread Verification Testing.

DEA 160 Phase 1 Testing

Test Will Consist of the Following:

Make Up and Break Outs with the Threads Cut as Follows:

1. A match box and pin set. Perfect matched set, no slop on the tolerances.

2. A box with tolerances on the low side and a pin with tolerances on the high side.

3. A pin with tolerances on the low side and a box with tolerances on the high side.

4. A box with tolerances on the high side and a pin with tolerances on the high side.

5. A box with tolerances on the low side and a pin with tolerances on the low side.

DEA PROJECT 160System Development

Funds: 5 participants @ 30k each 1st Phase 100k each 2nd Phase
