Mitigation of Wax Crude Oil problems in Wellbore Case Study: AL-RAWAT Oil Field (R-C10 well)

Abstract

Wax deposition in wellbore tubing at shut-in status is one of the major problems in ALRAWAT oil field. The main purpose of this research is to find suitable solution for wax deposition in tubing as one of the major problems in ALRAWAT oil field .One of the main objectives of this study is to optimize wellbore production by select feasible technique based on heating solutions. Production optimization techniques (software) applied to determine optimum location of electrical heater in tubing of (R-C10 well) Al RAWAT. The optimum depth was found to be 5100 ft .The experimental results of this study show that the main reason for wax deposition in tubing at well shut-in status was the wax apparent temperature which was found at high degree of (68oC). Analyzing procedure is applied to get feasible technique to solve the problem of wax in (R-C10) depend on the advantages and disadvantages of these techniques , the study provide a role of this procedure as table. Keywords: Wax Precipitation, Wax Deposition, Wax Appearance Temperature.
