Optimization of well gas rates for offshore gas-condensate field

摘要

Condensate recovery enhancing on offshore gas-condensate fields cannot be realized using the cycling process due to significant financial costs and technical difficulties. Such a problem could be handled by the redistribution of well gas rates. This redistribution assumes the solution the following problem: maximize the total condensate production at a given time interval then gas production requirements are met. The results of solving the problem are functions, each representing the change in the well gas rate over the time. The problem is transformed to the linear optimization model so that the solution algorithms based on the linear programing theory can be applied. Their tests showed, that these algorithms easily find the solution of the optimization problem; and the condensate recovery is greater or equal than the one obtained by the optimization procedures implemented in Eclipse. The search time is an order of magnitude less than the one required by Eclipse.
