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.

In situ evaluation of gases and liquids in low permeability reservoirs

A coal seam producibility determination system may include a fiber optic cable, the fiber optic extending from a DAS interrogation unit into a wellbore. The DAS interrogation unit may be located at a surface. The wellbore may intersect a plurality of coal seams to be measured, the coal seams comprising fluid and solubilized gas. The wellbore contains wellbore fluid and the wellbore has a wall. The fiber optic cable extends along the plurality of coal seams. The coal seam producibility determination system may further include a spectrometer, the spectrometer located at the surface or within the wellbore. The coal seam producibility determination system may also include an optical window, the optical window in optical communication with the spectrometer, the optical window in fluid communication with the wellbore fluid.

Coal seam gas production determination

An analytical method that establishes a thermodynamic equilibrium or known dynamic relationship between the concentrations of gases, natural gas liquids and oils or pressures of gasses in an isolated zone of a shale, or group of distinct shale gas intervals, with the concentrations of fluids or pressures of gasses in a wellbore penetrating the shale interval or intervals. An analytical method for identifying the chemical composition of gas, natural gas liquids and oils and determining their origin in an isolated zone of a shale, or group of distinct shale gas intervals with the identification of chemical composition of gas, natural gas liquids and oils in a wellbore penetrating the shale interval or intervals. A surface measurement apparatus capable of performing the measurement ex-situ. A downhole measurement apparatus capable of reliably performing the measurement in-situ and a downhole straddle-packer assembly capable of isolating part of, or an entire shale interval.

In situ evaluation of unconventional natural gas reservoirs

The invention subject of this disclosure teaches a method of determining a production factor for a carbonaceous material reservoir, the method comprising: providing a well in a carbonaceous material reservoir; providing unsampled fluid at a depth in the well; placing a sensor adjacent to the unsampled fluid and performing a measurement on the unsampled fluid; using data from the measurement to determine a partial pressure of a solution gas in the carbonaceous material reservoir; and determining a production factor for the carbonaceous material reservoir from the partial pressure of the solution gas.
