摘      要：Significant advancements in tiltmeter technologies has improved our ability to map the geometry of hydraulic fractures at great depth. This Department of Energy sponsored effort with widespread industry collaboration has extended the capability of near-surface tiltmeters to image details of the hydraulic fracture process at depths approaching 10,000 feet. Improvements in the analog-digital circuitry, the data-logger, and the remote mechanical leveling device has enabled us to install tiltmeters in relatively deep holes where the degradation affects due to the natural-cultural noise sources on the tilt-signal are minimized. Another benefit of utilizing this technology in the oil and gas industry is that it provides valuable information on the geometry of these hydraulic fractures, which is important for production field design. Modeling tilmeter data with algorithms that take into account details of the fracture growth process and the local geology are currently being developed, especially since recent results indicate that signal strength from deeper hydraulic fractures may be stronger than previous models had suggested. © 1997
