Introduction

Shale, with its inherent heterogeneity and anisotropy, has always been problematic in many operations ranging from seismic exploration, well-log data interpretation, well drilling and well-bore stability problems, to production. An ongoing industry-academia partnership has been formed to conduct a study aiming at bridging the gap between invariant characteristics at nano scale of sedimentary rocks and their macroscopic properties.
The results of this study have been implemented in a user-friendly software, QGGMS™, which is capable of predicting macroscopic mechanical properties such as Young's modulus, Poisson's ratio, etc. of shales or shaly rocks providing the mineral composition and porosity.
To meet field application demands, the software allows direct importing of log data for real-time onsite prediction of mechanical characteristics of shaly formations. To cope with the unavoidable uncertainties associated with log measurements, QGGMS™ provides uncertainty simulation for the obtained results utilizing Monte Carlo method.

Features

QGGMS™ includes the following features:

1. Import LAS log data.

2. Give the mechanical properties of formation in a virtual format.

3. Perform uncertainty analysis for selected intervals.
