Earth Data Incorporated's geophysical logging suite is geared towards environmental and water-resources investigations. Earth Data's geophysical surveys can assist with characterizing lithology and determining fracture location, borehole flow and fluid conditions.

Earth Data Incorporated's geophysical logging system has a total depth capability up to 2,500 feet. A field computer provides control of the digital system and allows maximum flexibility for various on-site digital and printed outputs. Copies of digital logs are provided to the customer in the field.

Earth Data Incorporated provides fully-equipped vehicles to conduct geophysical surveys and borehole color TV surveys in wells, boreholes and mine openings throughout the Eastern United States. Geophysical surveys can be conducted at any time, day or night. All field personnel are trained and certified as specified in Federal Regulation 29 CFR 1910.120. Our clients include drillers, water companies, consulting firms, hydrogeologists, regulatory and research agencies, municipalities and industries.
