ABSTRACT
The Zechstein 2 Carbonate
reservoir is part of the Basal Zechstein Unit, which developed in the northeast
Netherlands mainly as an anhydrite platform at the southern fringe of the
Southern Permian Basin. The facies within the Zechstein 2 Carbonate Member
reflect platform, slope, and basinal settings. The subsurface data collected
in the exploration and development of the Zechstein fields have led to
a detailed sedimentological model for the Zechstein 2 Carbonate Member.
Prospects in the Zechstein
2 Carbonate Member are seismically defined as structural highs at the Top
Zechstein 2 Anhydrite level. As exploration moves towards the search for
more subtle traps, 3-D seismic data become indispensable.
Basal Zechstein isochore
maps determined on 3-D seismic volumes display the topography of the Basal
Zechstein platform. Using the sedimentological model, these maps are used
to estimate gross reservoir thickness. Variations in reservoir parameters,
especially porosity, of the Zechstein 2 Carbonate Member are reflected
in the seismic response. Through synthetic seismic modeling, 3-D seismic
data allow spatial prediction of average reservoir porosity. The Collendoornerveen
exploration well demonstrates the successful application of the quantitative
interpretation techniques. |
