... Abstract Production optimization such as optimal gas lift allocation to maximize oil production can be a non-smooth and non-convex optimization problem. In this paper, we describe the derivative free Discrete Gradient Method (DGM), with local, global and multi-start search options for non...

... Abstract Continuous flow gas-lift wells are susceptible to hydrodynamic instability (heading), which causes cyclic variations of the wellhead pressure, oil and injected gas flow rates. Flow instability is an important issue in the design and operation of continuous flow gas-lift installations...

... Abstract The typical GLR sensitivity curves for gas-lift design and optimization are obtained for a constant wellhead pressure when the system sensitivity study is for a single well system and for a first-stage separator pressure or fixed pressure when the system sensitivity study...

... early stages of production as the well gets closer to the water-oil contact. As will be seen in the next section the increase in the water-cut drives the requirements for gas-lift during the first months of production. Gas-Lift Requirements An initial simulation was performed to compare...

... In the very beginning, storage trucks were used to deliver nitrogen, but since this method was so expensive, an in situ nitrogen generation project was implemented, using the membrane technology. In this way, it was possible to reduce 50% the total costs in three gas lift wells. In March 21...

... evaluating different techniques, gas lift was determined to be the most effective and economical means of dewatering. Each well's characteristics were analyzed to determine the gains that could be achieved through continuous unloading. The analysis also identified the key wells that would benefit...

... Abstract 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. Due to the complexity of the process, some times the production engineer...
