The shear dilation mechanism has been exploited to stimulate hot dry rock reservoirs and gas reservoirs (Pine and Batchelor[1], Vychytil and Horii[2], Mayerhofer et al.[3 In addition, microseismicity generated by shearing is commonly observed during conventional hydraulic fracture treatments[4...

... 1. INTRODUCTION Hydraulic fracturing has long been used to induce fractures in rock masses for reservoir stimulation and other purposes. However, it is rare to have the opportunity to measure the actual stress changes that are caused by a full scale hydraulic fracture as it grows. Recently...

Paper Number: ARMA-2000-0423
... ABSTRACT ABSTRACT: This paper describes the first successful use of hydraulic fracturing to induce a goaf event and control the timing of caving events in Australia. Hydraulic fractures are initiated at 7 to 10 m above the bottom of a thick conglomerate roof and, because of the low vertical...

... ABSTRACT ABSTRACT: Laboratory hydraulic fracturing tests were performed in cylindrical specimens of highly porous Berea sandstones (17% and 25%). We were able to raise the borehole pressure so as to induce hydraulic fractures by increasing the viscosity of the borehole injection-fluid as well...

Paper Number: ARMA-2000-1129
... ABSTRACT ABSTRACT: Hydraulic fracturing (HF) is commonly used to stimulate hydrocarbon reservoirs. The artificially generated fractures are generally assumed to develop with two symmetrical wings. However, in natural settings many cases are observed where fracture wings are not symmetrical...
