Development of an Advanced Hydraulic Fracture Mapping System Final Report for U. S. Department of Energy DE-FC26-04NT42108 Reporting Period Start Date: April 15, 2004 Reporting Period End Date: January 31, 2007 By: Norm Warpinski Steve Wolhart Larry Griffin Eric Davis Pinnacle Technologies, Inc. 9949 W. Sam Houston Parkway N. Houston, Texas 77064 Abstract The project to develop an advanced hydraulic fracture mapping system consisted of both hardware and analysis components in an effort to build, field, and analyze combined data from tiltmeter and microseismic arrays. The hardware sections of the project included: (1) the building of new tiltmeter housings with feedthroughs for use in conjunction with a microseismic array, (2) the development of a means to use separate telemetry systems for the tilt and microseismic arrays, and (3) the selection and fabrication of an accelerometer sensor system to improve signal-to-noise ratios.
