Gas Lift Optimization at BP-IndonesiaDual String Gas Lift WellWith Injection Pressure Operated ValveBy: Gatut WidianokoWeatherford Artificial Lift Systems

Abstract North West Java Oil (NWJO) field located offshore Indonesia is operated by BP. This mature oil field (discovered during 1970s) has approximately 950 wells, and ninety percent (90%) are produced with dual gas lift systems. In thirty (30) years of production, the reservoir pressure has decline to an average between 500 600 psig at the mid-perforation depth (ranging from 3000 - 4000 ft TVD). Discharge pressure of lift gas is 680 psig at compressor station(s).

In June 2001, BP-Indonesia management made a decision to focus on optimizing their gas lift wells. After significant discussion, it was decided to take a non-conventional approach with respect to gas lifting dual wells by using Injection Pressure Operated valves (IPOs).

Process Overview: create effective optimization organization design of dual gas lift utilizing IPO valves experiences and solutions for eliminating gas robbing.

Offshore Northwest Java Oil Field

Steps in Gas Lift OptimizationBP Management - focus on gas lift optimization90% of wells produced by dual gas lift Optimization Team selectedTeam reviews in-house (limited) gas lift expertise; decision made to contract gas lift services from Weatherford; GL engineer visits Jakarta office and NWJO field facilitiesOptimization Team reviews report; proposals submitted Weatherford; further discussions held regarding projectOptimization Team contracts three (3) positions for implementation of NWJO project for 6 month period (including clause for additional 6 month extension)Objectives determined and proper means of tracking or trending established; workable reportsResults of optimization reviewed weekly and monthly

Well Review by TeamOld Oil Field with more than 30 years oldHigh FGOR with 1000 : 1 or moreLow PI with only about 1 3 blpd / psiLow Production with about 200 - 500 blpdLow Static Pressure with average ~ 600 psiLimited Casing Pressure with ~ 600 psi onlyFlowing Tubing Pressure is about 180 psiShallow well - reservoir depth ~ 3000 ft TVDLimited data (SBHP and PI is normally unknown)Old wells - may have leaking valve or tubingSome gas lift valves installed 5-10 years ago

Dual Gas Lift Design Lessons LearnedEnough Kick Off (KO) and Operating (OP) Pressure to reach deepest point of injection is requiredDifferential pressure between KO and OP is ~10% of casing pressure, (or at least 50psi) to cover all unloading valves of both strings are closed when surface casing pressure is set at OPUse graphical method to select best point of injection of both strings and best draw down (200-300 psi) of both stringsCalculate by computer setting pressure Ptro; select best port sizes and gas injection rate required All pressure settings (Ptro) of unloading valves for both strings must be selected according to surface closing pressureSurface closing pressure of both strings must be at least 20 psi above OP, and 10 psi less than KOAvoid gas robbing - depth point of injection of both strings must be close or equal; same thing in port size

UXA-4S/L Well SchematicREDESIGN WELLSince mandrels were installed in well, optimization on this will be done by redesign.

Main job is how to determine best point of injection of both strings for optimum drawdown and to avoiding robbing.

To perform this job, gatheringcomplete information of both strings is required.

Since SBHP data is old enough, and to ensure static pressure therefore SBHP survey is required to be performed.

Gain Results After Gas Lift RedesignGas lift valves were calibrated in workshop, then installed; unloading of tubing strings was done with at least 650 psi as KO. After well unloaded, then gas injection rate was adjusted to maintain surface casing pressure at 640 psi, or OP. Following chart summarizes results after gas lift optimization: OPERATING PRESSURE: 640 psi
