Objective
To characterize the inert gases associated with and emanating from deep crustal fluids, as an aid to evaluation and identification of geological structures.
The main elements of the proposed research plan are as follows :
1) Use He, Ne, Ar and Xe isotopic compositions of natural gas samples from known hydrocarbon reservoirs existing at different depths within the crust. Where possible samples will be obtained as a function of depth within particular regions.
The contributions of atmosphere, crustal radiogenic and mantle components will be resolved using the procedures outlined above, and their relative contributions with depth quantified. Limits will be placed on the transport mechanisms governing migration of deep source inert gases. Initially sampling will be concentrated on well-characterized fields in the North Sea, Po Basin, Vienna Basin and Aquitaine Basin.
2) Evaluate the nature and mechanism of rare gas retention and release from crustal rocks with differing thermal histories.
3) Attempt to quantify He-flux through selected regions of the crust where deep geothermal or hydrocarbon potential may exist at depth. The degassing history of the crust will be studied at two sites in the Po Valley. Both very shallow biogenic gases and very deep thermogenic gases in the Vienna Basin and the gas fields west of Debrecen will extensively be studied.
4) By combining results of (1), (2) and (3) above, attempt a full characterization of inert gas characteristics associated with emanation from deep crustal fluids.
5) Develop (as required) field sampling techniques appropriate to unforeseen opportunities to obtain deep source gases.
6) Publish a map with the isotope abundances in Europe.
