Paper presented at the 53rd U.S. Rock Mechanics/Geomechanics Symposium, June 23–26, 2019
Paper Number: ARMA-2019-0033
... ABSTRACT: This paper demonstrates two modifications to Heuer's (1995 and 2005) tunnel inflow calculation method that are intended to improve the accuracy of inflow estimates. The first improvement is concerned with updating the method of characterizing hydraulic conductivity. Rather than...

Paper Number: ARMA-2016-829
... Abstract: Fluid transport during hydraulic fracturing can be either proppant or asperity dominated. In the absence of proppants, dilatancy of the natural fractures during shear reactivation is required to provide sufficient aperture and hydraulic conductivity. If a hydraulic fracture...
