Description
Electrical Resistivity Imaging (ERI) by Four Oaks Geophysics provides 2D, pseudo-3D, or 3D subsurface imagery by measuring soil interaction with induced electrical currents. This geophysical testing method maps bedrock depth, rock fractures, and karst features, penetrating strata beyond hard refractors unlike seismic refraction. Survey depth reaches 20 to 25 percent of line length using up to 56 or 112 electrodes. Additionally, Wenner Array and four-pin ASTM G57-06 testing measure soil conductivity for transmission lines, solar farms, and wind farms.

Description
The OFITE Digital Resistivity Meter (Product Code 130-87) accurately measures the electrical resistivity of fluids, slurries, and semisolids ranging from 0.01 to 400 ohm-meters. Designed for drilling fluids testing and laboratory analysis, its digital LCD display shows resistivity, temperature across 14 to 140°F (-10 to 60°C), and automatic NaCl concentration from 0.2 to 300 kppm without requiring manual nomographs. It includes built-in calibration testing and a transparent, removable Lucite cell powered by two 9-volt batteries.
Best for
Drilling fluids engineers, Laboratory technicians and Measuring resistivity and NaCl concentration of drilling muds, slurries, and semisolids

Description
Geo-Resistivity Survey is a specialized geophysical surveying service offered by MEGA Philippines. The service utilizes electrical measurements conducted on the ground surface to determine the depth and thickness of underlying subsurface resistivity layers. It characterizes site lithologies and geological materials employing techniques such as vertical electrical sounding (VES) and electrical resistivity tomography (ERT) tailored for groundwater exploration, mining, and geotechnical site investigations across the Philippines.
Best for
Project developers, Mining companies, Groundwater exploration and Mining site surveys
