Desorption canister Unconventional reservoir Instruments

The system determines the amount of gas contained in a coal or shale core sample by means of a desorption process. The apparatus follows the guidelines described in the ASTM D7569/D7569M standard practice for direct desorption, in which the released gas volume is monitored over time. Immediately after coring coal or shale rock, a sample is inserted into a hermetic canister to measure gas evolution over time equivalent to the amount of contained gas.

The system allows desorption at reservoir temperature by placing the canister in an electric thermostatic bath. Whole core desorption canisters can also be utilized with cuttings.
