Geophysical bedrock mapping is the process of identifying and mapping the bedrock formations beneath the earth's surface. It is an important technique used in many areas of geology, engineering, and environmental science. The main goal of geophysical bedrock mapping is to create a detailed image of the subsurface geology, which can help geologists and other professionals to better understand the geologic history of an area, solve engineering complexion, create safe environmental remediation criterion.

ERT can accurately identify subsurface structures, including the location and orientation of rock formations, faults, fractures, and other geological features thus engineering hazards that would otherwise remain unforeseeable. This information is crucial for planning the horizontal drilling path and pipeline route, understanding the underground migration of inorganic migration, foundation designs in civil construction, engineering solutions across an active tectonic site and environmental conservation.  

ERT can help reduce the risks associated with horizontal drilling and pipeline crossing, such as damage to the pipeline or surrounding environment. By identifying potential hazards before drilling begins, operators can take measures to avoid or mitigate these risks.
