Integration of Well, Core, and Seismic Previous HitDataNext Hit for 3D Depositional Environment and Reservoir Architecture Interpretation—Previous HitExampleNext Hit from Offshore Vietnam


Determining the distribution and uncertainty of rock properties in a reservoir is fundamental for building a robust 3D geological model for Previous HitfieldNext Hit development. Higher resolution 1D well and core information needs to be integrated with the lower resolution 3D seismic volumes with the appropriate appreciation of the scale, resolution and uncertainty of the Previous HitdataNext Hit sets. Sub-centimeter scale resolution can be achieved from detailed core description with sedimentary structures, trace fossils, grain size distribution, bed thicknesses, bed boundary characteristics, and bed stacking patterns giving indications of sedimentary processes that can be combined to infer depositional environments in a 1D vertical arrangement. Utilizing analogs of modern day and ancient systems, models can be proposed for the 3D distribution of sedimentary body architecture and rock property distribution. These analog models serve as starting points that need to be modified to the local parameters developed from seismic Previous HitdataNext Hit sets to build a Previous HitfieldNext Hit specific geological model. Understanding the resolution of the seismic Previous HitdataNext Hit is necessary to determine what size and shape of the sedimentary bodies can be resolved to take the 1D depositional environments interpreted from core away from the well bore into 3D seismic space. Previous HitDataNext Hit from offshore Vietnam serves as an Previous HitexampleNext Hit of this integration of well, core and seismic Previous HitdataTop sets for understanding reservoir distribution.
