Resumen

Resource evaluation and Planning Exploration Project represents a key factor to incorporate new future reserves into the booking of Hydrocarbon Potential for any oil and gas company. In order to mitigate the risk and increase the probability of success (POS), it is necessary to carry out different techniques that allow establishing a better approach and more accurate evaluation. One of this mitigation technique is the understanding of the relationship between seismic attributes anomalies and fluid-lithology rock geometry distribution. The aim of this paper is to show, the effectivity of using the combination of different seismic attributes, previously calibrated by rock physic from existence gas bearing reservoirs, as a reference seismic response in order to evaluate the potential DHI. As result of this project, the methodology applied allowed to reduce the geological risk through the accurate seismic delineation of 41 gas prospects during the analysis of probability of effective trap; and Probability of effectiveness of reservoir properties. 19 prospects have more than 70% of POS, 12 prospect with 42%, and 10 prospects with less than 40%. Finally, in order to generate an attractive exploration portfolio for future investment has done the ranking of 41 exploratory opportunities in 14 stratigraphic levels. © (2023) by the European Association of Geoscientists & Engineers (EAGE).
