Abstract
Official abstract text for this publication.
A method of optimizing production of wells using choke control includes generating, for each well, an intermediate solution to optimize the production of each well. The generating includes using an offline model that includes a mixed-integer nonlinear program solver and includes using production curves based on a choke state and a given wellhead pressure. The method further includes calculating, using a network model and the intermediate solution of each well, a current online wellhead pressure for each well. The method further includes setting the intermediate solution as a final solution based on determining that a difference between the current online wellhead pressure of each well and a prior online wellhead pressure of each well is less than a tolerance amount. The method further includes adjusting, using the final solution of each well, at least one operating parameter of the wells.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of optimizing production of a plurality of wells using a control mechanism, the method comprising: generating, for each well of the plurality of wells, an intermediate solution to optimize the production of each well of the plurality of wells using an offline model comprising a mixed-integer nonlinear program solver and using a plurality of production curves based on a state of the control mechanism and a given wellhead pressure; calculating, usin…
