Abstract
Summary
Basement reservoirs proved to include proliferous hydrocarbon (HC) accumulations and many authors admit they should be explored equally with reservoirs in sedimentary basins. Still complex geology, lack in understanding of sourcing and trapping mechanisms, and usually low quality of seismic image in basement make exploration in crystalline basement extremely challengeable. In the research presented we illustrate that HC accumulations in basement are associated with significant gravity anomalies. Thus including gravity to joint inversion with seismic and well data to build single consistent model of the subsurface allows to minimize exploration risks.
