... the gas lift or ESP operation. All the methods studied revived well-X. The significant result was the ability of GL which was 1509 2708 STB/ day, and ESP has achieved the highest oil production of 2708 STB/ day. The economic range was found to be [(2-4.2), (2- 3.6), and (1-2.7)] MMSCF/D for CH 4 , N 2...

... Abstract Nowadays gas-lift is still a very expressive artificial lift method, for instance considering the whole Brazilian oil production profiles, gas lifted wells are responsible for 30% of monthly production. Due this huge importance, the injection efficiency should be ensured to avoid lid...

... the production sustainbale even at low reservoir pressures. The high gas content of the reservoir fluid, deep reservoir zone, and adequate bottom hole pressure of Halini X1 favored gas lift to be more viable compared to other ALS methods both technically and economically. The results of the gas lift simulation...

... plants are becoming more complex, so advanced control systems can support the operators and play an important role to improve stability and profitability. This paper will present an advanced control algorithm for gas-lift optimization of offshore wells that aims to increase oil production. It will also...

... component is included. Until a steady state is reached again the operator must decide every period (typically every hour or every half an hour) on which wells to close or open, how much gas lift should be injected, how much the chokes should open or close in order to maximize oil production. gas lift...

.... These options are not limited but include modify gas-lift allocations, surface back-pressures and increase facilities capabilities. This paper describes the methodology applied to the development of an integrated asset modeling study for a brown offshore oilfield in Brazil and the technical challenges faced...

... metallic (HSDM) material is one such technology. HSDM incorporates high ultimate-compressive strength (UCS) and an engineered disintegrating mechanism tailored per application. The high-strength rating of HSDM accelerated the development of disintegrating gas lift valves (GLV) which reduce non-productive...

.... It started production in 2003, and in 2013 went through a re-development program presenting all the challenges of a typical brownfield project. It included the hook-up of 4 new wells, installation and commissioning of the production bundles, subsea control modules and hydraulic, electric and gas-lift flying...

... wells. As the study matured over the next 15 months to the Final Investment Decision, the BJSA Redevelopment Project became a full blown brownfield flagship project for the operator, which included 3 new gas-lifted infill wells plus 1 appraisal/producer well into a new reservoir, replacement...

Impact of gas lift In addition, a gas only wellbore fluid column should be considered with a shut in pressure equal to that of the design pressure of the flowline. This case is the absolute worst case scenario...
