Abstract

Summary

Unconventional hydrocarbon reservoirs such a shale gas is an important target for natural gas exploration in Poland. Recognition and exploration of unconventional gas reservoirs require different approach compared to conventional hydrocarbon deposits. The key process is to estimate geomechanical parameters which can be used for recognition, characterization and mapping spatial distribution of gas shales. This paper presents an application of AVO inversion for estimating geomechanical parameters such as Lambda-Rho and Mu-Rho. The study shows, that two interesting depth intervals – Ordovician and early Silurian gas shales exhibits low values of Lambda-Rho and Mu-Rho. Our analysis also revealed pre-drilled anomaly, which may indicate a presence of Cambrian tight gas sandstone.
