What is drift in casing?
Drifting means measuring a pipe’s inner roundness. Drifting is typically performed by passing a cylindrical mandrel (Drift) through the length of the pipe to detect occlusions. It occurs both at the pipe mill and in the field.

What is a drift run?
Drift racing is a motorsport event where the athletes are judged by the quality of their drifts, including but not limited to the angles that they approach the turns (driving line), the continuity of their drifts (driving line, speed, and drift angle), the proximity to the lines (drift angle and execution), and their …
What is J55 casing?
The J55 API-5CT casing pipe is a comparatively low steel grade in oil drilling. It is widely applied for shallow oil and gas extraction. Because of its low cost among other grades of steel, it enjoys wider applications, can be generally used in shallow wells, geothermal wells, and water wells.
What size well casing do I need?
The casing determines the size of the pump: 5″ and 6″ casing will accommodate a 4” submersible pump: 5 – 90 Gallons Per Minute (GPM) 8″ casing will accommodate a 6” submersible pump: 50 – 200 GPM. 10″ casing will accommodate an 8” submersible pump: 100 – 800 GPM.
What is the most common range of drill pipe?
Range 1 (R1) is shortest in length, more common for sizing production tubing or casing, and ranges from 18 to 22 ft. Range 2 (R2) is considered the standard length for drill pipe and ranges from 27 to 31 ft. Range 3 (R3) is common in casing and also deployed in deep water drilling applications.
How do I choose a casing grade?
The appropriate casing grade for any application typically is based on pressure and corrosion requirements. Since the well designer is concerned about the pipe yielding under various loading conditions, the casing grade is the number that is used in most calculations.
What is a dog in oil and gas?
DOG drilling on gauge sub was specifically designed to deliver at-the-bit reaming performance. Its short-body design and durable cutting structure enable placement between the bit and the mud motor in directional applications.
What is the purpose of a dog collar in oil drilling?
Also known as a pup joint, a pony joint is a short joint of drill pipe, drill collar, casing or tubing used to adjust the length of the drill string.
