calculations and fault mechanics invariably involve the use of a rock failure criterion …

The casing deformation issues have occurred widely in Changning-Weiyuan National Shale
Gas Demonstration Area. During multi-stage volume fracturing process, a large amount of …

In recent years, the exploration and production of oil and gas from Bakken formation in
Williston Basin have proceeded quickly due to the application of multi-stage fracturing …

A road-cut exposure located on the southern flank of the Arbuckle anticline along the
Interstate-35 provided the opportunity to document in detail the lithological heterogeneities …

Experimental and field studies show that shales are strongly anisotropic, a fact that is
neglected in most hydraulic fracture models. Using a two-dimensional numerical model …

Rock mechanical properties are critical for drilling, wellbore stability, and well stimulation.
There are usually two laboratory methods to determine rock mechanical properties: static …

Current analytical methods to assess rock strength for borehole stability, stimulated volume
calculations and fracture and faulting almost exclusively involve the use of the Mohr …

Many correlations have been developed for converting dynamic and static elastic moduli for
various rock types. The ability to make quick and simple estimates of static elastic moduli …
