Abstract
SummaryA great deal of effort has been devoted to finding geophysical techniques for measuring the hydraulic fracture azimuth. This paper discusses a comparison of seven different measurements to determine the azimuth in a sandstone formation at a depth of 1,050 ft [320 m]. The azimuth was determined as N95E, but significant differences existed between some of the results. This is of fundamental importance because in developing new measurements, the limits of these must be found and honored.Of particular interest are the results from microseismic monitoring. The lack of results suggests that remote (e.g., surface) monitoring for seismic events may be impractical for normal, sedimentary, hydrocarbon-bearing formations.
