Abstract
A canister for measuring the natural gas content of rock cores which (1) has an inner core-containment bag made of non-permeable plastic which can be flash evacuated, collapsing around the core and thus minimizing the amount of air present and improving the quality of the gas analyses and (2) which prevents the released gas from reacting with the outer canister. A procedure for using gas-sampling bags to periodically collect the gas released from the core so that (1) the volume of released gas can be measured at a later date using more convenient and precise laboratory methods, (2) the gas can be readily transported and stored, and (3) the gas can be easily submitted for analysis.
Claims22
A core degassing apparatus comprising:
- a. a body,
- b. said body having a first body end and a second body end,
- c. a cap sealably and releasably connected to said first body end,
- d. a sealing disk, sealably connected to said second body end whereby an air tight chamber is formed,
- e. a core containment bag disposed within said chamber,
- f. said core containment bag having a core containment bag first end and a core containment bag second end, and
- g. said core containment bag first end fluidly connected to the exterior of said chamber.
A method of core degassing comprising:
- inserting a core segment into a core containment bag,
- sealing said core containment bag,
- sealing said core containment bag in an air tight chamber,
- removing gas samples desorbed from said core segment, and
- measuring said gas sample volumes.
