Soft Sensing for Gas-Lift Wells

SPE Annual Technical Conference and Exhibition, 2004
Abstract This paper considers the use of extended Kalman Filtering as a soft-sensing technique for gas-lift wells. This technique is deployed for the estimation of dynamic variables that are not directly measured. Possible applications are the estimation of flow rates from pressure measurements or the estimation of parameters of a ...

Probe Testing of Gas Lift Valves for Effective Performance Prediction and Better Gas Lift Design

Proceedings of Latin American and Caribbean Petroleum Engineering Conference, 1999
Abstract Optimum production from a gas lift well mainly depends on proper injection gas quantity, injection pressure and depth of injection. The quality of down hole gas lift valves plays a crucial role in achieving maximum efficiency of a gas lift system and un interrupted oil and gas production . This study carried out by probe testing

Smart Gas Lift Valves Eliminate Multiple Slickline Trips in Gas Lift Operations

Offshore Technology Conference-Asia, 2014
In many gas lift systems, dummy valves are loaded in side-pocket mandrels to isolate the annulus from the tubing where pressurization is required to test the tubing, test the annulus, set a hydraulic packer, or activate an isolation device. If the well then requires gas lift to unload the completion fluid or to assist the well to flow, slickline ...

CALCULATION OF GAS LIFT LIFTS

Themed collection of papers from Foreign International Scientific Conference «Trends in the development of science and Global challenges» Ьу HNRI «National development» in cooperation with AFP. June 2022, 2022
The indicator of the water content of the produced products is one of the most basic and important technological parameters of the operation of producing oil and gas condensate wells. Decision-making in various fields of oil production depends on this parameter, starting from the regulation of well operation and the implementation of measures aimed at ...

A New Gas Lift System

Fall Meeting of the Petroleum Branch of AIME, 1953
Abstract A system for intermittent or continuous gas lift which uses rubber balls as pistons to prevent wasteful gas slippage is described. Two parallel strings of tubing are used. The rubber balls are forced down one string and the production is lifted up the other.

Gas Lift Valves Troubleshooting to Improve the Gas Lift Wells Performance

International Science and Technology Journal
Gas lift valves can aid in the unloading and production of a well. With the valves properly spaced and correctly pressured and proper select of the port size, unloading proceeds in a stage-by-stage, valve by valve manner to the ideal point of lift, and maximum liquid production is reached.

CO2 Gas Lift – Is It Right For You?

SPE Mid-Continent Operations Symposium, 1999
Abstract Gas lift can be installed in producing wells within a CO2 flood utilizing the nearly pure injection CO2 or the mixed hydrocarbon/CO2 gas returning to the production station. Lift gas injection rates can be varied to correspond to the water content resulting from the water-alternating-gas (WAG) results.

SOLAG: An Intelligent Gas Lift Optimization System for Continuous and Intermittent Gas Lift Wells

SPE Latin America/Caribbean Petroleum Engineering Conference, 1994
Abstract Offshore production operations in Lake Maracaibo field are characterized by having an average of 4,500 gas lifted wells, producing from more than 400 different reservoirs. These complex processes require constant surveillance to allocate the proper gas injection rate for each well, based on available gas from each one of the ...

Developing a Novel Temperature Model in Gas Lifted Wells to Enhance the Gas Lift Design

2014
In the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. The produced liquid flow rate is a function of gas injection rate and injection depth. All the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that ...

Gas Lift Design and Performance

International Petroleum Exhibition and Technical Symposium, 1982
ABSTRACT The optimum design of a continuous flow gas lift installation is dependent upon the critical combination of a number of pertinent variables, including well performance index, gas in solution, static reservoir pressure, tubing size and injection gas pressure.
