Rock physics analysis of Early Miocene reservoirs in Sureste offshore basin, Gulf of Mexico

Rock physics aims to link geological and reservoir properties to the elastic and seismic parameters. We can avoid the ambiguities in seismic interpretation by understanding the link between geological parameters and rock physics properties, such as fluid-lithology, sand-shale and porosity-water saturation. In Sureste basin of Gulf of Mexico, the Early Miocene has become one of the emerging play to explore with the recent oil discovery in 2020. This oil discovery shows very good DHI. However, in the recent years, a few Early Miocene dry wells were drilled in the same area. A clear DHI is seen at some of the prospect areas identified and some prospects doesn’t show any DHI. Wintershall Dea carried out sub-regional rock physics analysis to understand the AVO floor of Early Miocene rocks, which will be further used to evaluate and de-risk the Early Miocene leads/prospects identified in the study area. The authors are presenting the results from the study in this abstract.
