What is radial cutting torch?

What is radial cutting torch?

Radial Cutting Torch tool is a patented cutting device used to sever tubing, casing, drill pipe, and coiled tubing without the use of explosives or hazardous materials, making it one of the safest pipe cutting tools on the market.

What is pipe recovery in oil and gas?

Pipe recovery is a specific wireline operation used in the oil and gas industry, when the drill string becomes stuck downhole. Pipe recovery is the process by which the location of the stuck pipe is identified, and the free pipe is separated from the stuck pipe either by a backoff or a chemical cut.

What is drill string in oil and gas?

A drill string on a drilling rig is a column, or string, of drill pipe that transmits drilling fluid (via the mud pumps) and torque (via the kelly drive or top drive) to the drill bit.

How do you find the depth of a stuck pipe?

Determine how many feet of free pipe without free pipe constant table

1. FPC = As x 2500.
2. As = (OD2-ID2) x 0.7854.
3. Depth of stuck pipe = (Pipe stretch in inch x free point constant (FPC)) ÷ Pull force in thousands of pounds.
4. a) Determine free point constant (FPC):
5. b) Determine the depth of stuck pipe:

What can happen if the drill string is rapidly pulled from the well?

The resulting piston effect generates a surge pressure that is added to the hydrostatic pressure. Excessive surge pressures can increase the wellbore pressure to such a degree that it can lose circulation. Conversely, when a drill string is pulled out of a hole, fluid flows down the annulus to fill the resulting void.

How do you find the free point of a stuck pipe?

1 ) Determine the free point constant (FPC) by this following formula:

1. FPC = As x 2500.
2. As = (OD2-ID2) x 0.7854.
3. Depth of stuck pipe = (Pipe stretch in inch x free point constant (FPC)) ÷ Pull force in thousands of pounds.
4. a) Determine free point constant (FPC):
5. b) Determine the depth of stuck pipe:

What is pipe stretch?

1. n. [Well Completions] The increase in length resulting from the combination of forces acting on a string within the wellbore. The principal factors resulting in an increase in string length are the weight of the string itself and the effects of thermal expansion.

What is Drawworks in drilling rig?

A drawworks is the primary hoisting machinery component of a rotary drilling rig. Its main function is to provide a means of raising and lowering the traveling block. The segment of drill line from the drawworks to the crown block is called the “fast line”.

What is round trip in drilling?

1. n. [Drilling] The complete operation of removing the drillstring from the wellbore and running it back in the hole. This operation is typically undertaken when the bit becomes dull or broken, and no longer drills the rock efficiently.

What is a drilling jar?

Drilling jar is a equipment that runs in the bottom-hole assembly to free the drill string when it gets stuck during drilling operations. It is used to deliver an impact to the stuck point by releasing strain energy stored in the drill string, acting like a hammer.
