This paper presents a case history describing the use of three-dimensional (3D) surface seismic and downhole microseismic data to understand and optimize a fracturing stimulation completion project performed in the Horn River basin (HRB) shale.

The behavior of the hydraulic fractures is interpreted from the data, and a geological theory is then used to further explain the observed data. The theory and observations are then used for completion and stimulation designs on the subsequent well pad.

The target intervals are in the HRB of northeastern British Columbia. They consist of Devonian age clastic sedimentary rocks of the Muskwa and Klua formation that overlie the carbonates of the Keg River formation. Fig. 1 illustrates the HRB geological schematic in the general area.
