A Control Strategy for an Oil Well Operating via Gas Lift
نویسندگان
چکیده
This article proposes a control strategy for an oil well operating via gas-lift. The well model is implemented in the OLGA simulator (Scandpower) using an orifice valve (no moving parts) downhole with control in the gas lift surface valve and production choke. The dynamic identification uses the knowledge of the process static gain as the nonlinear static block of a Hammerstein model representation. An Adaptive Notch Filter was designed to damp the resonant system frequencies. Simulation results showed that the control strategy proposed was able to move the well operating point along the region of economical interest and to reject the perturbation imposed on the downstream side of the production choke.

Stabilizing gas - lift well dynamics with free operating point ⋆ ⋆
Gas-lift is one of the most used artificial lift methods worldwide. In Brazil it responds for more than 70% of the total oil production. Gas-lift wells are known to present oscillatory behavior associated with phenomena like heading and density wave. This work presents an innovative way to control these oscillations. The approach adopted controls the well dynamics without fixing any operational...
متن کاملOptimization 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 کاملOptimizing and Stabilizing the Gas Lift Operation by Controlling the Lift Gas Specific Gravity
One of the factors which affects the gas lift performance is specific gravity of a lift gas (or the Molecular weight), which can influence the gas solubility in oil and has a direct effect on the gas lift performance. There are some previous researches which have included the lift gas specific gravity in their modeling, but in none of them, a comprehensive research about the effect of lift gas ...
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 کاملAn Approach Based on Neural Networks for Gas Lift Optimization
Using a model-based optimization, a neural network model is used to compute the optimal values of gas injection rate and oil rate of a gas lift production system. Two cases are analyzed: a) A single well production system and b) A production system composed by two gas lifted wells. For both cases minimizing the objective function of the proposed strategy shows the ability of the neural networks...
