Abstract

Crude oil water cut is the percentage mass of water in all the liquids, i.e. increase of water in crude oil. Water cut is the significant parameter along with the Gas Oil Ratio (GOR) for the crude oil to surely indicate the water content in the reservoir fluids. Water cut is commonly expressed in percentage, this paper describes a method of determining water cut percentages with tubing variations (inch), in order to have an applicable tubing size in water cut wells. There are several ways to determine the well’s performance, single way is the tubing performance relation curve, also known as the tubing performance curve (TPR/TPC). The TPC is used with the inflow performance relationship (IPR) to predict the performance of specific well, with aim to decide the performance of oil well before well optimization conducted, Inflow Performance Relationships (IPR) curve is used. The curve illustrated relation between well production rates (Q) to bottom-hole pressure (P). The IPR method calculation based on fluid phase that flowing in the well through the conduit to surface. The result variation water cut percentages optimizing with an appropriated tubing size (Inch) for wells. Thus, the effect of tubing size could be optimized the production rate that will be produced.
