Simplified transient-IPR modeling in intermittent gas-lift and plunger-lift systems
Journal of Petroleum Science and Engineering, 2019Abstract By solving the diffusivity equation on a periodic varying production problem, one can arrive at a transient inflow-performance relationship (IPR) model. This IPR model can then be coupled with a wellbore model to understand intermittent deliverability from wells with an artificial-lift system (ALS), such as periodic gas lift and plunger lift.

Intermittent gas lift in Aghajari oil field, a mathematical study
Journal of Petroleum Science and Engineering, 2004The gas lift is a widely used method of artificial lift, for which there are different options. Previous work in this regard to optimize the continuous gas lift (CGL) of Aghajari oil field located in the south of Iran was promising. A new intermittent gas lift (IGL) simulator is developed considering all aspects of this artificial lift method including

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 ...

Optimal and heuristic scheduling for intermittent gas lift operations
Computers and Industrial Engineering, 1988Abstract The purpose of this paper is to study the scheduling problem in the intermittent gas lift operations, and to present a mixed integer programming (MIP) formulation for solving it. Some heuristic methods are also developed to gain insight into the gas lift scheduling problem of larger problem size.

Evaluation of Surface Back - Pressure for Continuous - And Intermittent - Flow Gas Lift
JPT, Journal of Petroleum Technology, 1963Abstract To study continuous- and intermittent-flow gas-lift wells, it is necessary to evaluate the facilities that the well fluids must pass through to reach the storage point. This paper deals with surface back-pressure and its effect on continuous-and intermittent-flow gas lift.

Field-Scale Research on Intermittent Gas Lift
SPE Mid-Continent Operations Symposium, 1999Abstract 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

INTERMITTENT GAS LIFT OPTIMIZATION IN ROSA MEDIANO FIELD
Proceedings of Latin American and Caribbean Petroleum Engineering Conference, 1999AbstractRosa 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 ...

A simulation model for oil production by intermittent gas lift technology
SOCAR Proceedings, 2023The 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.

SOLAG: An Intelligent Gas Lift Optimization System for Continuous and Intermittent Gas Lift Wells
SPE Latin America/Caribbean Petroleum Engineering Conference, 1994Abstract 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 ...
