Abstract

ABSTRACT One of the most frequent problems with drilling is the circulation of sludge (loss of circulation). Loss of circulation (lost sludge) is defined as part or all of the drilling mud (drilling fluid) when it is circulated, so that the fluid enters the formation being penetrated. The intense LPP E well is the type used to prove the presence or absence of hydrocarbons. The main target of drilling is in the formation of root gutters, where the formation of root gutters consists of rocks and limestone which is a place of circulation loss. In this formation has a large permeability and porosity, the status can result in the problem of missing mud. The analysis conducted on the problem of lost circulation is to analyze the occurrence of lost circulation which will be studied based on aspect of formation and drilling mud aspect. Based on the aspect of formation done by analyzing lithology data from mud log data and based on drilling mud aspect is done by calculating formation pressure, sludge density, hydrostatic pressure of sludge, formation gradient, formation fracture gradient, and pump pressure determination. From the results of the analysis conducted it can be seen the cause of the occurrence of lost circulation that occurred in the drilling of wells E in LPP field. Keywords : Drilling, Lost Circulation
