Gravity

Contrasts in earth’s gravitational field can often be attributed to local changes in the density of subsurface materials or the presence of engineered structures. Sensitive gravity meters are utilized to measure the gravitational field at designated points within the area of interest. The resulting values are processed and mapped to illustrate spatial variations. The scale of the investigation may be regional if you are interested in larger features like petroleum reservoirs or cover a local area if you are interested in very small contrasts associated with karst or voids.

Applications for gravimetric investigations include:

  • Detection and delineation of subsurface karst features or voids
  • Regional geologic structure mapping
  • Basement topography and sediment thickness mapping
  • Hydrocarbon exploration
  • Mineral exploration
