20100228485 | METHOD FOR INTEGRATING RESERVOIR CHARGE MODELING AND DOWNHOLE FLUID ANALYSIS - A method for estimating properties of fluids in rock formations at selected locations within a geologic basin includes generating an initial model of the basin. The model includes as output spatial distribution of at least rock formation mineral composition, rock formation porosity and composition of fluids in the rock formation porosity. An initial estimate of fluid composition is generated for at least one rock formation at at least one selected location within the basin. A sample of fluid is extracted from pore spaces of the at least one rock formation from within a wellbore drilled therethrough. Composition of the fluid sample is analyzed from within the wellbore. The initial model of the basin is adjusted such that model predictions substantially match the analyzed fluid composition. The adjusted model is used to generate an initial estimate of fluid composition at at least one additional geodetic location within the basin. | 09-09-2010 |
