Reservoir Characterisation of the Lower Miocene Sediments, Matzen Field

This study aims to provide a three dimensional characterisation of the stratigraphic reservoirs in the Lower Miocene succession in the Matzen Field, incorporating available data into the development of an integrated sedimentological model following a sequence stratigraphy approach. The newly developed sequence stratigraphic setting acquired an important meaning for this particular field. For instance, it shows if one or more production units are included in one single system tract or if each production unit corresponds to a separate compartment in individual system tracts; additionally defines seal stratigraphic intervals represented on transgressive system tracts. Sedimentological and stratigraphic findings were used to discriminate and distribute facies on a three dimensional structural model of the Lower Miocene production units, determining net pay sand reservoir bodies that were used to calculate volumes of hydrocarbon in place characterising the hydrocarbon potential on each production unit.
