Abstract

Pipe sticking is an event where the drilling pipe is stuck or a fracture occurs. Usually what causes the pipe to be stuck or pinched is the viscosity in the mud is greater, causing the drill string movement to be hampered, it can also be caused by differential pressure or the fall of a foreign object into the drill hole. In this final project, a study will be carried out on the "AB" well because the drilling of this well experienced a pipe sticking problem. In writing this final project, 2 scenarios will be carried out, namely the calculation of Spotting Fluid using diesel and reducing the weight of the mud with the aim of reducing hydrostatic pressure. The pinch point has been found at a depth of 8083.99 ft. then for the handling, the weight of the mud is reduced in order to reduce the value of the hydrostatic pressure. In the bouyancy factor parameter, a value of 0.832 is obtained, then the density value of the drilling fluid is obtained in the table which is 82.29 lbs/ft3 Or 1318.159 kg/m3. And the total volume of the well obtained results of 284,557 bbl or 45,241 m3. In the spotting fluid method when the pipe sticking point has not been found, the diesel volume value is 41.25 bbl. In the mud weight reduction method when the pipe sticking point has been found, the mud weight reduction value is9.212 ppg. And obtained a differential pressure value of 63.255 psia. So that thebalance well and the pipe can be released.
