Summary

This paper describes the application of ESG Canada’s FRACMAP service using induced microseismicity to map the spatial and temporal growth of a series of hydraulic fractures in Carthage, Texas. A series of 10 fracs in 6 UPRC wells were monitored over a period of 21 days in January 2000. For each treatment well, an offsetting production well at a distance between 1000’ and 1750’ was used as an observation well. A 12-level, triaxial geophone array was deployed just above the reservoir in the observation well. ESG’s Hyperion Microseismic System was used to detect induced micro-earthquakes, archive the seismograms, and automatically compute event locations and source parameters (magnitude, stress and energy release). The real-time microseismic results were then transmitted via a local network to a visualization computer at the frac site, where petroleum engineers could view interactive 4d maps of the frac geometry.
