Keywords: cycling process, development, gas condensate field, production, well development, condensate, reservoir losses, reservoir pressure

Annotation:

In the process of depletion development of gas condensate fields, gas condensate falls out in the reservoir (retrograde losses), and a significant part of it becomes inaccessible for production due to being below the threshold of its hydrodynamic mobility. This process is closely related to the reservoir pressure decrease during a reservoir development. Therefore, it is necessary to search for solutions and cost-effective ways to maintain reservoir pressure. The authors of the article present studies of the conditions for using the cycling process to increase the condensate recovery factor in the conditions of a gas condensate field located in the waters of the Ob Bay.
