The quality of basin modeling results, such as pressure and hydrocarbon migration pathways, depend on the quality of rock properties derived from wells and through Previous HitseismicNext Hit Previous HitinversionNext Hit. Previous HitSeismicNext Hit attributes representing present day rock properties, as well as fluids and gases in the system, give us an idea of reservoir connectivity and of lateral and vertical seals in a 3D petroleum system. If utilized in a high resolution 3D basin model, they provide a framework in which hydrocarbons are assumed to migrate from source rocks to reservoirs.
Non-uniqueness of Previous HitseismicNext Hit Previous HitinversionNext Hit results in more than one possible basin model, i.e. more than one possible pressure field, more than one hydrocarbon migration scenario, etc. Any inconsistencies between hydrocarbon migration pathways and saturations derived from basin modeling and well calibration Previous HitdataNext Hit may indicate potential problems with Previous HitseismicNext Hit Previous HitinversionNext Hit. If analyzed properly, the inconsistencies can be utilized to improve Previous HitseismicNext Hit Previous HitinversionNext Hit through iterative corrections of Previous HitseismicNext Hit impedance / porosity / capillary entry pressure transforms.
This paper presents methodology and workflows for building integrated Previous HitseismicNext Hit inver­sion/basin models. Case studies from Kutei Basin (Indonesia) and from the Gulf of Thailand introduce the process and show how Previous HitseismicNext Hit Previous HitinversionTop combined with invasion per­colation based basin modeling improved our understanding of complex petroleum systems of SE Asia Tertiary basins.
