Well CAT-07H is a producing oil well located in Cath Offshore Field. This well hasbeen producing using gas lift method which its injection gas is supplied by COM-182 compressor. In June 2019, the production of this well was interrupted by the fault of COM-182 which initially supplied 1100-1300 psi injection pressure at CAT-07H casing to only 800-1000 psi after being repaired. Due this change of injection parameter, CAT-07H was no longer able to be produced due to insufficient injection pressure. In the other hand, the well having relatively high water cut (75%) and depleted reservoir pressure made this well can no longer flowing naturally. The most possible solution for this problem is to optimize gas lift injection depth to match the new supplied gas pressure. In this paper CAT-07H is the sample well candidate to be evaluated for GLPO installation. CAT-07H is initially a gas lifted well which receive gas from COM-182 compressor. Due to decrease in performance of COM-182 compressor, gas parameter received on CAT-07H from COM 182 is no longer suitable with existing gas lift installation. Based on evaluation, gas pressure generated from this compressor decreases from 1100-1300 psi range to 800-1000 psi range. Based on this data, gas lift optimization is required to adjust gas lift on CAT-07H to meet the new pressure range. 800 psi is used as design parameter with maximum injection gas rate of 1 MMSCFD. Based on the evaluation in this thesis, it is found that gas lift can be optimized using GLPO method by changing the injection point to 2900 ft with punch port diameter if 0.15 inch which can be acieved using 1606 L puncher. After the optimization using GLPO on CAT-07H, production rate can be optimized to 2532 BFPD with net production of 633 BOPD. [ABSTRACT FROM AUTHOR] |
