... cross-linked treatment at 80 – 88 barrels/minute. The resulting microseismic events were recorded in a vertical observation well using an array of seven sensors spaced at 100 feet intervals, spanning ~600 feet along the wellbore, and ~125 feet above the target reservoir. Based on 148 microseismic events...

... fracture treatment, a 3-component (3C), 8-level borehole seismic array was deployed in a nearby well for hydraulic fracture monitoring. Due to high bottom-hole temperature (BHT) of 175 º C, operational procedures were developed to successfully acquire Microseismic events generated by the hydraulic...

.... The microseismic data were obtained using a dense near-surface permanent array spanning ~30 square miles. Based on 1,229 microseismic events, inferred fracture half-lengths range between ~423 ft and ~675 ft. About half the lengths of most of these fractures are contained within the target reservoir interval...
