A rapid correlation method for petroleum population mapping within individual petroleum reservoirs: applications to petroleum reservoir description

  • Dag A. Karlsen

While oil-oil and oil-source rock correlation is a routine part of most exploration programmes, it is only rarely that detailed comparison of oil compositional variations within reservoirs are studied. Although many mechanisms serve to homogenize reservoir fluids, petroleum populations of varied composition can be defined and related to reservoir contiguity and the history of field filling from diverse source rock assemblages. The definition of these heterogeneous petroleum populations, while of great significance to exploration problems related to field filling and definition of prospective sub-traps, is also an under-exploited development tool. Conventional approaches to reservoir definition rely heavily on sedimentological and downhole geophysical analysis of formations coupled with flow testing. Petroleum population mapping may allow direct definition of filling/production conduits within fields if mixing processes can be understood and quantified.
