METHOD AND APPARATUS FOR QUANTITATIVE MEASUREMENT OF HYDROCARBON PRODUCTION WITH FLUID IMBIBITION

摘要

A method of characterizing hydrocarbon production from a core sample obtained from a reservoir includes saturating the core sample with at least one saturating fluid. A flow of an imbibing fluid is initiated across a surface of the saturated core sample with the core sample subjected to confining pressures and maintained at a controlled temperature. One or more properties (such as volume or pressure) of countercurrent flow of the saturating fluid and one or more properties (such as volume or pressure) of cocurrent flow of the saturating fluid is measured over time in response to the flow of the imbibing fluid. Characteristics of the core sample can be measured before and after exposure to the imbibing fluid to assess changes to the core sample.
