INVESTIGATION OF OVERPRESSURE AND MINERALOGY EFFECT ON ROCK MECHANICAL PROPERTIES OF MONTNEY SHALE GAS RESERVOIRS IN BRITISH COLUMBIA, CANADA

Numerous studies have been conducted to estimate dynamic rock mechanical properties
(RMP) and rock strength of shale gas to predict accurate value when no core available.
However, the existing correlations did not consider the overpressure condition and
mineralogy in its correlations. These important parameters have to be considered to
improve the accuracy of the correlations to optimized hydraulic fracturing design and
operational strategy. The objective of this study is to improve the static and dynamic
RMP correlations and develop a novel model of Unconfined Compressive Strength
(UCS) by considering overpressure condition, mineralogy, and TOC content in
Montney shale, British Columbia, Canada.
