Wave Technology Group has developed a new and powerful technology to aid in the exploration for hydrocarbons. Power Imaging - PI (Patent Nos.7227362 7248052) is a geophysical prospecting method that utilizes the electric power grid as a continuous source of energy for investigating the earth's subsurface geological structure. The electric power grid induces electromagnetic waves in the earth. These electromagnetic waves are at specific frequencies, which are harmonics and sub-harmonics of 60 cycles. The waves propagate as plane waves and encounter the various geologic boundaries. Those boundaries having dielectric and/or conductivity contrast reflect a portion of the waves back to the earth's surface. With continuous sourcing from the electric power grid, the waves resonate between the subsurface boundaries and the surface of the earth. In this manner, the waves become organized so that there is a direct relationship between the many resonating frequencies and the depths to the various geologic boundaries.

PI technology is useful at any stage of the exploration process. As with all geophysical methods, interpretation is improved by incorporating all available geoscience information. Because of the low cost of data acquisition the PI technology is used as an inexpensive and independent confirmation of seismic amplitude anomalies. It is used to fill gaps or low resolution areas in existing seismic data. Or, PI technology is used to evaluate areas prior to seismic acquisition.

PI is used for the structural imaging of the earths subsurface, and PI provides a means for the direct detection of hydrocarbons. PI technology has excellent depth resolution, no environmental impact and minimum acquisition costs. The field recording apparatus consists of an antenna, an amplifier and a digital storage device. This equipment, which weighs less than ten pounds, is easily transported and operated by one person. The data recorded at each site requires only five minutes to collect and normally, depending on access, six to eight sites can be recorded per hour. The collected field data is then processed in the office, and an interpretation is made. From beginning to end the final product is usually delivered to the client within two weeks.
