Abstract

This study aims to analyze the potential of lost circulation zones in the RJ well at the CP field by calculating hydrostatic pressure, formation pressure, and formation fracture pressure. Lost circulation occurs when drilling fluid is lost into the formation, which can disrupt the drilling process. In this study, calculations were made for hydrostatic pressure, formation pressure, and formation fracture pressure at various depths of the well. The results show that at a depth of 741 ft, the hydrostatic pressure is 330.22 psi, formation pressure is 318.66 psi, and formation fracture pressure is 982.88 psi. Meanwhile, at a depth of 9517 ft, the hydrostatic pressure reaches 5438.78 psi, formation pressure is 5290.31 psi, and formation fracture pressure is 7237.24 psi. The significant difference between hydrostatic pressure and formation pressure leads to the occurrence of lost circulation. In conclusion, the potential for lost circulation in the RJ well is caused by hydrostatic pressure being higher than formation pressure. This study provides important insights into the factors influencing lost circulation and is expected to serve as a reference for future drilling operations.

Abstract

Lossicirculation isione of theiproblems thatioften occursiin theidrillingiworld where loss of circulation or loss of circulation of mud is interpreted as a loss of circulation in a small amount or all of the drilling mud when it is circulated, so that when the drilling takes place, the circulated mud enters the drilling zone. penetrated formation. The "HF-05" well in the "KANAAN" fieldiis aidevelopmentiwell thatiaimsito proveithe existenceiof oil and gas reserves in Sukra District, Indramayu Regency. The loss circulation problem that occurred in the "HF-05" well occurred at a depth of 1945 mMD, route with a total loss of 278 bbl with a mud weight of 1.19 sg. The methodology used in handling loss circulation is collecting the necessary data, calculating hydrostatic pressure (PH), calculating drilling hydraulics, and identifying the causes of loss circulation by comparing hydrostatik pressure (PH) with formation pressure. Then carry out countermeasures using loss circulation material (LCM) type Calcium Carbonat. The results of countermeasures for loss circulation using loss circulation material (LCM) type Calcium Carboante in the "HF-05" well were successful with hydrostatik pressure (PH) lower than formation pressure (PF).
