• Geotechnical and Civil Engineering Investigations

  • Locating tunnels, caves, sinkholes, and fault- fractures

  • Dam and levee investigations

• Groundwater Exploration

  • Irrigation

  • Drinking water

  • Saline/freshwater interface mapping along coastlines and petroleum drilled areas

• Environmental and Monitoring Investigations

  • NAPL (DNAPL and LNAPL) pollution research for remediation of hydrocarbons

  • CO2 Sequestration Time-Lapse Monitoring

  • ASTM D7007: Geomembrane Leak Detection

• Bedrock and Landfill Mapping

• Grounding Surveys for Power Plants and Cell Phone Towers

• Archeological Investigation

• Borehole Logging

  • Short-Long-Leterolog-SP

  • Cross-borehole tomography

• ASTM G57: Wenner Soil Resistivity Test

• Underwater and Marine Studies

  • Determining sub-bottom geology for dredging purposes

  • Monitoring leakage in a dam

  • Mapping fresh and saltwater interfaces near shorelines or offshore

  • Characterizing the sub-bottom of estuaries

  • Measuring water column salinity variations

  • Mineral exploration (usually placer deposits)

  • Locating freshwater springs at sea (submarine groundwater discharge)

  • Distinguishing between hard rock, sand, gravel, silt, and clay

  • Gas Hydrate Exploration

  • Subsurface geotechnical site investigation for oil platforms

  • Sediment research

  • Fracture Imaging

  • Resistivity and IP studies for deep mining, oil/gas investigations

Use Cases:

EarthImager™ 2D is for use in geotechnical and geologic industries, including the following applications:

• Cave and void detection

• Depth-to-bedrock mapping

• Ground water exploration

• Mineral exploration

• Mapping environmental spills

• Monitoring environmental cleanup progress

• Aggregate mapping

Determining the best location for a well in a rural, underdeveloped area—so the individuals in the surrounding area have access to safe and clean drinking water—is an excellent use of the EarthImager™ 2D. Drilling is expensive and drill maintenance is even more so, so if an non-governmental organization (NGO) decides to drill a new well, they need to know with certainty where to place it. By using EarthImager™ 2D, the ground water exploration team can create a tomogram that shows where the best location for a producing well is.

Features:

• User-friendly Windows GUI.

• Seamless operation with AGI resistivity instruments.

• Survey planner with graphical model input, virtual survey with the actual command file, and inverse simulation with user-specified Gaussian noises.

• Topographic correction and printout of resistivity section with topographical features.

• Data editing for detecting and removing erroneous data points and bad electrodes.

• No software limit on number of data or number of electrodes.

• No limit on electrode array type or electrode location.

• Inversion progress bar to show the inversion status.

• Data misfit scatter plot and cross-plot.

• Reversal and horizontal shift of a profile.

• High-definition report quality plat-style printout.
