Abstract

The low production of a well oil field is a very serious problem that must be evaluated and resolved as soon as possible. Area X is part of field Y which is a heavy oil type oil field because it has a density of 17-22 API and a viscosity of 118 cp, in this area there are 403 production wells which are divided into a number of patterns, each well has a depth of around 600-700 ft. has an artificial lift of the Sucker Rod Pump type. Area X has been producing for approximately 12 years, and during that time span, several wells in areas that have large reserves showed lower oil production performance than expected, so the wells were labeled as underperforming wells. In this study, the evaluation carried out is to determine the wells that are classified as underperforming wells based on well capacity, explore the factors causing the under-performing through analysis of drilling reports, historical fluid production, historical oil production, Historical WHT, historical well problems. Historical well activities (well job) as well as comparing underperforming wells with nearby wells with much better performance. From the analysis that will be carried out, it can be concluded that the cause of underperforming wells in area X is low temperature and formation damage caused by loss of circulation during drilling and the right solution to overcome this problem is to carry out cyclic steam stimulation for low temperature problems and perform matrix acidizing for formation damage problems
