Modeling and Optimization of Plunger Lift Assisted Intermittent Gas Lift Installations
SPE Advanced Technology Series, 1994ABSTRACT 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.

Liquid Fall-Back Measurements in Intermittent Gas Lift with Plunger
SPE Annual Technical Conference and Exhibition, 1993Abstract 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.

Laboratory Study of the Behavior of Conventional Intermittent Gas-Lift
Volume 8: Polar and Arctic Sciences and Technology; Petroleum Technology, 2016The 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.

Hydrodynamic Model For Intermittent Gas Lifting of Viscous Oil
Journal of Petroleum Technology, 1984Abstract 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, 2001Abstract 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 ...

Selection of Optimum Intermittent Lift Scheme for Gas Lift Wells
Proceedings of University of Tulsa Centennial Petroleum Engineering Symposium, 1994Abstract 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 ...

Intermittent Gas Lift for Liquid Loaded Horizontal Wells in Tight Gas Shale Reservoirs
SPE Artificial Lift Conference and Exhibition - Americas, 2020Abstract The production from horizontal tight gas wells is affected negatively by the accumulation of liquids in the bottom of the well (i.e., liquid loading), to the point that additional hydrocarbon production is not possible. In this work we propose an artificial lift method for liquid-loaded horizontal wells, in tight gas shale ...

An Analytical Concept of the Static and Dynamic Parameters Of Intermittent Gas Lift
Journal of Petroleum Technology, 1963Abstract An analytical method for describing the events of pressure, velocity and liquid fall-back in relation to time and other well variables from initial injection to completion of an intermittent gas-lift cycle is presented herein.

POVLIFT: A Computer Program for Designing and Optimizing Intermittent Gas Lift
Petroleum Computer Conference, 1991Abstract A mathematical model of hydrodynamic processes i intermittent gaslift is described. The many facets of fluid flow accrue from continuous changes of the hydrodynamic and thermodynamic conditions, the mathematical solution of unsteady fluid flow was simplified by introduction of certain assumptions and boundary conditions.

Assessment of Intermittent Gas Lift Performance Through Simultaneous and Coupled Dynamic Simulation
Proceedings of SPE Latin American and Caribbean Petroleum Engineering Conference, 2005Abstract The assessment of Intermittent Gas Lift (IGL) by computer calculations using the mechanistic models found in the literature usually approaches the IGL's operating cycle as a sequence of independent non-interacting stages, occurring back-to-back, without overlapping in time; that approach restricts the system analysis to the ...
