Experimental validation of microseismic emissions from a controlled hydraulic fracture in a synthetic layered medium
MetadataShow full item record
A controlled hydraulic fracture experiment was performed on two medium sized (11” x 11” x 15”) synthetic layered blocks of low permeability, low porosity Lyons sandstone sandwiched between cement. The purpose of the research was to better understand and characterize the fracture evolution as the fracture tip impinged upon the layer boundaries between the well bonded layers. It is also one of the first documented uses of passive microseismic used in a laboratory environment to characterize hydraulic fracturing. A relatively low viscosity fluid of 1000 centipoise, compared to properly scaled ...
