Borehole Logging | GeoSearches Inc.

Borehole-geophysical logging provides a wealth of critical information for gaining a better understanding of the subsurface conditions required for environmental and groundwater studies. Geophysical logs provide unbiased, continuous, and in-situ data and typically sample a larger volume compared to drilling samples.

Delineation of Hydrogeologic Units

Different subsurface hydrogeologic units display a wide range of capabilities for storing and transmitting groundwater and contaminants. Borehole-geophysical logging provides a highly efficient method to determine the thickness and character of the different geologic materials penetrated by wells and test holes. This information is necessary for the proper placement of screens and casings in water-supply wells and for characterizing and remediating groundwater contamination.

Definition of Groundwater Quality

Groundwater quality is highly variable, and contamination can result from both natural and man-made sources. Integration of water quality sampling with borehole-geophysics logging provides a more complete picture, whether the objective is to remediate a contaminated aquifer or develop a water supply well.

Determination of Well Construction & Conditions

Wells are the access points to the groundwater system. Therefore, knowledge of their condition and construction is important, whether they are being used for groundwater supply, remediation, or monitoring. The location and condition of screens and casings can be rapidly evaluated with geophysical logging.
