Print this pageFluid Kinematics in the Stepwise Fill and Spill of Oil in Hydrocarbon Reservoirs Observed Using Fluid Inclusions in Reservoir Grains
Information from oil inclusions in sedimentary grains and diagenetic cements complement data from other disciplines about kinematics in the stepwise filling and spilling of hydrocarbon reservoirs. These include geochemical data showing oil with a normal alkane profile and biomarker evidence for biodegradation, showing some oil accumulated after a biodegradation event, or solid fluorescence in core below oil zone demonstrating changes in the depth interval of oil zone due to seal failure or structural growth.
Fluid inclusion data need to be calibrated by documenting patterns of oil inclusion attributes in reservoirs with constrained fluid kinematics When this is done they provide useful insights about such things as petroleum systems and the relative exploration-risk associated with each of source, reservoir, trap, migration, timing, and preservation.
Case histories will be presented of hydrocarbon reservoirs with constrained fill histories to calibrate OIA attribute data. Case histories will be presented to show how fluid inclusions data provide new insights about fluid kinematics of oil accumulation in discovery wells where knowledge of fluid history is incomplete.
