Estimation of fluid loading in dry gas wells Available to Purchase

One of the problems with wells in water-driven dry gas reservoirs is liquid loading. Liquid loading causes the gas well's production to stop if treatment is not carried out. Three wells in a gas field off the coast of Java have been producing gas since 2015. Well #2 began experiencing a problem in 2016 due to liquid loading. The well experienced a decrease in gas production rate and a sharp increase in water production rate before the well stopped producing. Meanwhile Well #1 and Well #3 were still producing. These two wells also experienced a decrease in gas production rates, but the increase in water production was still relatively much lower. In this research, an estimate was made of when Well #1 and Well #3 would also experience liquid loading problems. The analysis was carried out by comparing the predicted decrease in gas rate with the critical gas flow rate in these wells. The Turner, Coleman, Nosseir, and Li equations were applied for critical flow rate estimation. Based on a comparison of the predicted gas flow rate and critical gas flow rate, Well #1 will experience liquid loading problems between February 2026 and December 2027. While Well #3 will experience liquid loading problems between December 2027 and July 2029.
