A vehicle for chewing gum box of capture for gas carbonaceo, collecting process in place and examination of small concentration of gas carbonaceo dissolved in water and process for the collection and examination.At the local, small concentration of Methane Dissolved in water.

摘要

A method for the on-site collection and examination of small concentrations of a carbonaceous gas, e.g. methane, dissolved in a body of water overlying an earth formation to predict hydrocarbon potential of the earth formation under the body of water, the formation being a source of carbonaceous gas, comprises: (i) at a known geographic location sampling the water at a selected flow rate and at a selected depth; (ii) continuously vacuum separating the water into liquid and gas phases; (iii) separating a selected carbonaceous gas from interfering gas species in the presence of an air carrier vented to atmosphere at a known flow rate; and (iv) quantitatively oxidizing the selected gas and then cryogenically trapping an oxidant thereof in the presence of said air carrier to provide for an accurate isotopic examination. i
