Investigation of Intermittent Gas Lift by Using Mechanistic Modeling
SPE Production Operations Symposium, 1995ABSTRACT Intermittent gas lift is a cyclic process which can be divided into four stages. This paper describes a mechanistic model for the intermittent gas lift system based on fundamental physical principles. The model accounts for reservoir inflow performance, fluid properties, two-phase flow in the tubing, gas flow in the tubing ...

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 ...

Monte Carlo Simulation of Vertical-Separators Handling in a Network of Intermittent Gas Lift Wells
SPE Production & Facilities, 2004Summary To date, most of the research concerning the separation process has had a deterministic approach because of its orientation to steady-state-flow regimes. However, this assumption is far from true when many artificial intermittent gas lifted (IGL) wells are connected to the same separator.

A Methodology to Determine the Liquid Column Height of Intermittent Gas Lift Wells
Canadian International Petroleum Conference, 2002Abstract The estimation of the liquid column height of a well is one of the most complex problems in the petroleum industry. This complexity is mainly due to the behaviour of the wells' two-phase flow, which varies with pressure, temperature, viscosity, and other factors.

Downhole Pressure and Temperature Survey Analysis for Wells on Intermittent Gas Lift
International Petroleum Conference and Exhibition of Mexico, 1998Abstract The production of oil wells on intermittent gas lift can be increased by properly selecting the optimum cycle time and injecting the correct amount of gas at the required injection pressure in each cycle.

Data-Driven Monitoring and Optimization of an Intermittent Gas-Lift Operation
SPE Middle East Artificial Lift Conference and ExhibitionAbstract Gas lift is an extensively used artificial lift technique in the oil and gas industry. However, operators often shift to intermittent gas lift for low productivity index, reservoir pressure or high-water cuts, or due to the limited availability of gas (IGL).
