Before starting leak off test drilling procedures, gauges should be checked for accuracy. Also, the upper-pressure limit should be determined. It is so simple to run leak off test drilling but if you exceeded certain pressure, you may break the formation and a loss of circulation may occur. Leak Off Test Best Practice Pre-job Procedures. …
Surging or swabbing pressures in drilling describe pressure changes in the annulus resulting from pipe movement. The swabbing occurs when the drill pipe is pulled from the well, forcing mud to flow down the annulus to fill the void left by the pipe. However, the surging occurs when the drill pipe is lowered into the …
Overpull Drilling is the maximum pull exerted on a stuck drill pipe without causing failure in the Drill String.

Drilling jars are one of the BHA components that should be run with the drill string to help free stuck pipes. There are two common types of drilling jars: hydraulic and mechanical. Hydraulic jars use the pressure the string generates to apply an impact load. In contrast, the mechanical type uses a spring-loaded design to create an impact load. This …
