The Place of Passive Seismic in E & P

The increase on the demand for Passive Seismic especially in the domains of exploration and production has most recently become a challenging field of opportunity. The method based on uncontrolled sources, requires an understanding and analysis of what we call passive events in a careful manner, so as not to be misinterpreted leading to a possible damage of its credibility. The objective of this presentation is to look at one of the methodologies that benefit from passive sources, and justify its use with case studies. Integrated Passive Seismic using P and S-wave travel times from natural micro-earthquakes can accurately estimate 3D Vp (structural) and Vp/Vs (lithologic) information of the subsurface. and reservoir related parameters.
