Abstract

In greenfield developments, production test data is often the only data available (other than analogues) that can be used to constrain dynamic reservoir behaviour. However, often the integration of production well-test data and its interpretation into the static and dynamic reservoir models is limited to the incorporation of the calculated Kh and skin values. A well-test of a gas bearing carbonate formation of a well drilled as part of a gas development drilling campaign is used. In addition, a care is taken to include well-test results into the static and dynamic reservoir models. This is because relatively coarse-gridded simulation models cannot reproduce detailed well inflow behaviour due to the lack of discretization. As a result, the assumption of directly using well properties (kh and skin) determined from analytical well-test analysis in coarse gridded simulation models may not hold for all physical environments, particularly in the near-wellbore behaviour. Well-tests can be matched with detailed fine gridded single well models, which then should be used to upscale the well properties for coarser grids. The study illustrates how these "pseudo-well properties" can change as a function of full field simulation grid size and permeability thickness product (kh). In addition, this is done with out incorporation of the viscous stripping effect and the detailed geological features such as small fractures, warmholes on the condensate behaviour of different grid sizes.
