| dc.description.abstract | Production oil wells in Duri field have a unique production system since it producing both from tubing and casing. Casing pressure is one parameter that could impact well production. High casing pressure will increase restriction and prevent oil flow from reservoir to wellbore. High casing pressure indicates lot of steam produce, and mostly there is sand associated in CVC fluid production. This produced sand could cause leaking in surface pipe. Therefore to prevent pipe leak, need to reduce sand production by installing choke/orifice. In opposition, this choke/orifice could create back pressure to reservoir. This study aims to determine the impact of increasing casing pressure on fluid production rate. The research was done by two methods: 1) vary opening casing valve from 100%, 75%, 50% 25% and 0% then conduct fluid production test for each opening valve; 2) increase choke size at producer wells by ¼” from current choke size. Result from this research show that for production rate will not significantly impacted on 75% opening casing valve; for 50% opening casing valve, production rate will decrease around 10% from normal rate; for 25% opening casing valve, production rate will decrease 30% from normal rate and 0% opening casing valve (closed), the well will not produce anything. The result also shows that by increasing casing choke size using appropriate flow process could increase well production. | en_US |
