IN SITU EVALUATION OF GASES AND LIQUIDS IN LOW PERMEABILITY RESERVOIRS

A method may include drilling a wellbore, the wellbore intersecting a shale formation at an interval of the shale formation and casing at least a portion of the wellbore. The method may also include perforating the casing at the interval to fluidly couple the interval and the wellbore, and liberatin...

Zusammenfassung:	A method may include drilling a wellbore, the wellbore intersecting a shale formation at an interval of the shale formation and casing at least a portion of the wellbore. The method may also include perforating the casing at the interval to fluidly couple the interval and the wellbore, and liberating free and absorbed gas entrapped within the interval. In addition, the method may include solubilizing in the wellbore fluid the free and absorbed gas, forming a plume comprising solubilized gas, and determining an identity and amount of solubilized gas in the plume.
