Analysis of Economy in the Improvement of Oil Production using Hydraulic Pumping Unit in X Field

: The wells of X fields are vertical wells with installed pumps being the Hydraulic Pumping Unit. The wells can still be optimized by improving the performance of N and SL by trial and error method. Based on optimation analysis result at well BM 1 by changing SPM and SL parameters on pump which installed with N 6 SPM and SL 100 inch got Qt equal to 144 bfpd, then converted to N 7 SPM and SL 100 inch so that there increase of Qt become equal to 199 bfpd And pump efficiency from 67% to 80%. While in the well BM 2 by changing the parameters of SPM and SL on pumps installed with N 8 SPM and SL 100 inch obtained Qt of 284 bfpd, then converted to N 10 SPM and SL 110 inch so that there is an increase of Qt to equal to 583 bfpd pump efficiency of 65% to 90%. In the economic analysis with Production Sharing Contract system can be known with non-capital investment of MMUS $ 0.150, obtained NPV contractor MUS $ 451.07, IRR > MARR,POT < 1 year and DPI 4.00.
