The combined gas continues to Gas Compression system for gas lift and gas injection purposes while some percentage of the gas flow to Acid Gas Removal Unit (AGRU) system for fuel gas...

...Introduction Plunger Lift Cycle An indicative plunger lift cycle is explained in Fig.2 . This cycle is applicable for both gas well and gas lift well applications, however, the B-Valve open period is only required for gas lift wells (PAGL/GAPL). Field Implementation Plunger Lift...

... the gas lift system into the production tubing downhole. Various parameters such as produced fluid viscosity, bottom hole pressure, well and flowline slugging, and oil production were monitored. The chemical injection rate was optimised based on the monitored parameters. Trials were performed...

... pressure, temperature, and fluid production index to design the depth for deploying the gas lift string. By employing gas lift for fluid evacuation to increase wellbore discharge and conducting continuous testing with the tubing string, this approach effectively addresses the challenges of low fluid yield...

...Case for Change Field A, located offshore Sabah, East Malaysia, is an oil field operated by PETRONAS Carigali Sdn. Bhd. Majority of the wells in the field are dual string oil producers that rely on gas lift as its artificial lift to boost and sustain its production. Being a brown field, Field...

... service was carried out at MB-2 onshore to carry out well maintenance and see the performance of the subsurface where from the results of the FGS, SBHP and TIT it was found that tubing leaks were suspected so that gas lift consumption increased. Network Modelling Software Simulation The MB-2...

... and chemical EOR. Abstract Field B is a mature oilfield in offshore Sarawak with all wells being produced with gas lift and electrical submersible pumps (ESP). An Enhanced Oil Recovery (EOR) project was initiated to maximize economic value of the field utilizing immiscible Water Alternate Gas (iWAG...

..., utilizing only gas lift as its main artificial lift method. Concern for alternative lifting methods has arisen since 2019, due to the limitation of gas lift injection capacity that is no longer adequate for the current and future development wells at that time. Considering this challenge, Saka Energi...

... In Continuous Gas Lift mode, the high-pressure gas helps reduce the density of the fluid column, resulting in a decrease in the flowing bottom hole pressure which facilitates lifting of the liquid. In Intermittent Gas Lift mode, high-pressure natural gas is injected at fixed intervals...

... Abstract Field X is a mature brownfield with aging facilities and relies heavily on gas lift as artificial lift. Field X runs gas lift compressors with a 4+1 operating philosophy. However, significant unplanned deferment up to 12% is associated with the gas lift compressors due to frequent...

... Abstract This paper shares the success of a cost-effective finite energy gas lift scheme implemented as a measure to temporarily replace shortcomings of field gas lift system. Given the lack of full artificial lifting, Field C oil production dropped by an order of magnitude with remaining field...

... and no gas lift facility in the tubingless well completion, thus these oil reservoirs cannot be produced. The previous solution that has been implemented is to do heavy workover, by cutting upper completion and replacing it with a new completion that includes a side pocket mandrel; or do a light workover...
