LIQUID OIL PRODUCTION FROM SHALE GAS CONDENSATE RESERVOIRS

摘要

A process of producing liquid oil from shale gas condensate reservoirs and, more particularly, to increase liquid oil production by huff-n-puff in shale gas condensate reservoirs. The process includes performing a huff-n-puff gas injection mode and flowing the bottom-hole pressure lower than the dew point pressure.

1. A method of producing hydrocarbons from a shale gas condensate reservoir, wherein the method comprises the steps of:
(a) determining dew point pressure of fluids in a reservoir formation; (b) injecting gas from the surface downhole into a wellbore of a well such that the injected gas flows from bottom-hole into the reservoir formation, wherein the step of injecting occurs over a first time period of a cycle period; (c) producing fluids from the same wellbore by flowing the fluids from the reservoir formation into the bottom hole and up hole to the surface, wherein
(i) the bottom hole flowing pressure is below the dew point pressure of the fluids in the reservoir formation, and(ii) the production of the fluids occurs over a second time period of a cycle period; and (d) repeating steps (c) and (d) for a plurality of cycle periods.
