ABSTRACT

Listening to the earth passively over time and using the information wisely has driven us to the “…next big thing..” according to the AAPG Explorer (April 2003) article. Passive seismic is becoming part of E&P planning in the Oil and Gas sector with case applications as the one described here. The objective of Passive Seismic Tomographic Inversion, using P and S-wave travel times from natural micro-earthquakes is to accurately estimate 3D Vp (structural) and Vp/Vs (lithologic) information of the subsurface. A very important byproduct is the use of observed information to extract specific reservoir parameters. An exploration case study will be presented and the power of the method to deliver interpretable results that also fit well data will be examined, furthermore a demonstration of reservoir related parameter estimation will be shown.
