Field-Scale Research on Intermittent Gas Lift

SPE Mid-Continent Operations Symposium, 1999
Abstract Experiments on intermittent gas lift were conducted in a field scale test loop to measure: a) the effect of injection pressure, liquid column length, formation gas-liquid ratio, crude API and gas flow rate injected per cycle on the liquid fallback and b) the dynamic behavior of gas lift pilot valves. The test loop

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 ...

Modeling and Optimization of Plunger Lift Assisted Intermittent Gas Lift Installations

SPE Advanced Technology Series, 1994
ABSTRACT A novel mechanistic model for the design of plunger assisted intermittent gas lift installations is presented. The model considers the complete production cycle: accumulation of reservoir fluids in the wellbore, annulus pressure build-up, plunger/liquid slug rise, liquid production into flowline.

A simulation model for oil production by intermittent gas lift technology

SOCAR Proceedings, 2023
The operating principle of the oil production by intermittent gas lift (IGL) technology and the mechanical processes occurring in it are complex with many different stages and many flows interacting with each other in each stage. This leads to many difficulties in calculating and optimizing oil well production system with IGL technology.

INTERMITTENT GAS LIFT OPTIMIZATION IN ROSA MEDIANO FIELD

Proceedings of Latin American and Caribbean Petroleum Engineering Conference, 1999
AbstractRosa Mediano is the field with the lowest reservoir pressure in Lake Maracaibo. For this reason, a large number of wells are currently producing on choke controlled intermittent gas lift. The objective of this work was to identify operating conditions that could be modified in order to optimize gas consumption and maximize liquid production.To ...

Liquid Fall-Back Measurements in Intermittent Gas Lift with Plunger

SPE Annual Technical Conference and Exhibition, 1993
Abstract This work represents the first part of a three - stage research program that consists of: a) lab scale test; b) Held scale test in an experimental well and c) adjustment of existing mathematical models based on experimental test and actual oil wells.

Hydrodynamic Model For Intermittent Gas Lifting of Viscous Oil

Journal of Petroleum Technology, 1984
Abstract A hydrodynamic model was developed for intermittent gas lift. Simulation results were verified by experimental tests conducted with a 60 ft high 3 in. diameter test facility using air and an oil with viscosity of 108 cp.

Intelligent Automation for Intermittent-Gas-Lift Oil Wells

Proceedings of SPE Latin American and Caribbean Petroleum Engineering Conference, 2001
Abstract Intermittent gas lift is widely used in the PETROBRAS onshore petroleum fields. The intermittent gas injection in the annulus between the tubing and casing causes a gas lift valve to open. This gas lift valve is a pressure driven valve installed in the lower part of the tubing and controls the amount of gas injected at the ...

Laboratory Study of the Behavior of Conventional Intermittent Gas-Lift

Volume 8: Polar and Arctic Sciences and Technology; Petroleum Technology, 2016
The intermittent gas-lift (IGL) methods still remain a practical recourse for the extended production of petroleum wells in the on-shore fields of Brazil. The IGLs are a natural candidate to substitute the continuous gas-lift (CGL) method at a late stage of reservoir depletion; as so the IGLs require modest adaptation to the CGL installation.

Selection of Optimum Intermittent Lift Scheme for Gas Lift Wells

Proceedings of University of Tulsa Centennial Petroleum Engineering Symposium, 1994
Abstract Maracaibo Lake wells are currently producing approximately 800 mstbd of crude oil from some 7000 wells. 90% of these well are in gas lift and approximately 760 wells are being lifted intermittently. Natural reservoir decline will increase the number of wells that will require intermittent lift at an estimated rate of 150 wells ...
