Abstract

The Upper Cretaceous Alderson Member is a prolific gas (biogenic) producer in western Canada. In the Hatton Gas Pool area (southwest Saskatchewan), Alderson Member strata from ten drill-cores have been examined and classified based on sedimentological and ichnological character. Core analysis has determined that Alderson Member deposits comprise thick intervals of pervasively bioturbated strata. Using spot-minipermeametry and high-pressure mercury injection porosimetry methods, the influence of pervasively bioturbated intervals on the overall resource potential of Alderson Member strata is evaluated. Results from permeability and porosity testing demonstrate that pervasively bioturbated rock fabrics appear to locally enhance the overall storage and vertical transmission of gas from Alderson Member reservoirs.
