Coal & Shale Gas Desorption

• Wireline Cores
• Conventional Cores
• Sidewall Cores
• Drill Cuttings

Entrada GeoSciences measures desorbed gas content of coals and shales using samples obtained from conventional cores, wireline-retrieved cores, sidewall cores, or cuttings. A mobile desorption laboratory is set up in the field. Samples of coal or shale are collected fresh from the well-bore and placed in pressure canisters. The canisters are placed in temperature-controlled water baths at reservoir or near-reservoir conditions. Desorbed gas measurements are made at timed intervals for twelve to twenty-four hours after being collected. The canisters are moved to our laboratory for continued desorption until the sample is depleted of gas after the initial gas measurements. Gas-in-place calculations are made once the gas content of the coal or gas shale is known.
