Abstract:
The present disclosure describes a method of recovering oil and gas from a hydrocarbon-containing reservoir generally having some degree of water saturation within the reservoir pore network by injecting a gas into the reservoir. The method applicable to reservoirs having high water saturation of about 50 percent or greater. High water saturation in a reservoir can cause excessive amounts of water to be produced to produce the hydrocarbons. Coproduction and management of this water is costly and burdensome to operations leaving many reservoirs of oil and gas are stranded, rendering the production uneconomic. The method described herein addresses this need and other needs. The injection gas (with or without other hydrocarbons) can coalesce with the hydrocarbons contained within the hydrocarbon-containing reservoir to form a continuous phase of hydrocarbons within the reservoir. Once the targeted volume of the injection gas is injected, the flow is reversed producing the gathered hydrocarbons.

Claim (Index 1):
A method, comprising:\n providing a gas; injecting the provided gas into a selected well bore in fluid communication with a hydrocarbon-containing reservoir having a first water-to-gas production ratio, wherein the hydrocarbon-containing reservoir comprises a gaseous hydrocarbon, wherein the provided gas is injected at rate of from about 10 mcfd or more to about no more than about 8,000 mcfd, and wherein at least most of the hydrocarbons produced by the well bore are gaseous hydrocarbons; ceasing the injection of the provided gas into the selected well bore; and gathering together from the hydrocarbon-containing reservoir by the selected well bore some of the provided gas and some of the gaseous hydrocarbons to form a gathered-gas mixture comprising the provided gas and some of the gaseous hydrocarbons from the hydrocarbon-containing reservoir; and producing through the selected well bore the gathered-gas mixture, wherein the hydrocarbon-containing reservoir producing the gathered-gas mixture has a second water-to-gas production ratio and wherein the second water-to-gas ratio is no more than the first water-to-gas ratio.
