6 FAQs about [Swiss down-the-hole drill rig recovery]

What happens if a drill rig gets stuck?

The drill rig cannot continue its operations due to stuck pipe. Since this causes expensive downtime, ranging from $10,000 to $1,000,000 per day, it is crucial to find a solution as soon as possible. Pipe recovery refers to the procedure by which the stuck pipe's location is determined and the free pipe is cut or backoffed from the jammed pipe.

Can you fish for wireline tools out of a hole?

In order to fish for wireline tools out of the hole, we must use different equipment than would be used for pipe recovery. Common wireline tool issues center around the cable being tangled or wadded in the hole, as well as the fact that attempts at fishing can pull the wireline out of the rope socket or part, further complicating tool retrieval.

How do you know if a drilling rig is stuck?

If the rig is able to circulate drilling fluid back to the surface that is often a good indication of differentially stuck pipe. One technique for freeing the stuck pipe, or avoiding the issue to begin with, is to rotate the pipe string while pulling out of the hole.

What is pipe recovery?

Pipe recovery refers to the procedure by which the stuck pipe's location is determined and the free pipe is cut or backoffed from the jammed pipe. This makes it possible to run fishing equipment down the hole later to grab onto and unstick the jammed pipe. Differentially Stuck Pipe

How does an overshot work in a drill rig?

Full Hole Locking Coupling Stabilized Locking Coupling The Latch Seat

How do you fix a broken logging tool?

If it is not possible to use either a side-door overshot or a cut-and-thread, then an alternative is to break the weakpoint, and then recover the cable and use the drill pipe to fish for the logging tool. If tool recovery is not an option, then a last resort is to push it to the very bottom of the hole, and then plug it using cement.
