Optimization of lift gas allocation in a gas lifted oil field as non-linear optimization problem
Proper allocation and distribution of lift gas is necessary for maximizing total oil production from a eld with gas lifted oil wells. When the supply of the lift gas is limited, the total available gas should be optimally distributed among the oil wells of the eld such that the total production of oil from the eld is maximized. This paper describes a non-linear optimization problem with constra...
متن کاملDeveloping a Novel Temperature Model in Gas Lifted Wells to Enhance the Gas Lift Design
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 decreases the accuracy of gas lift design. Also g...
متن کاملDecomposing the optimization of a gas lifted oil well network
Low pressure oil wells can be made to flow by the injection of gas into the well. The resulting flow from the well increases discontinuously with the amount of gas injected. A common way to model this is by introducing integer variables which results in a MINLP formulation. Such a problem can be solved efficiently by a specialised Branch & Bound code. However for more than about 200 wells a com...
متن کاملPreventing Instability Phenomenon in Gas-lift Optimization
One of the problems that sometimes occur in gas allocation optimization is instability phenomenon. This phenomenon reduces the oil production and damages downhole and surface facilities. Different works have studied the stability and suggested some solutions to override it, but most of them (such as making the well intelligent) are very expensive and thus they are not applicable to many cases. ...
