Geophysical Wireline Well Logging

Hydrogeological units have the ability to store and transmit incredible amounts of fluids form both confined and unconfined aquifers regionally. This makes it essential to understand that a borehole represents an access point to our ground-water system. Creating a critical need to learn what we can of the construction and condition of boreholes regardless if the intended use is for supply, monitoring, or remediation. Due to the highly variable sedimentological sequences within the Mississippi Embayment, observations indicate a related variability of ground-water quality and transmission rates of contaminants, further demonstrating the need to acquire borehole data.

Borehole-geophysical logging provides a highly efficient means to determine the character and thickness of the different geologic materials penetrated by wells and test holes. This information is essential for proper placement of casing and screens in water-supply wells and for characterizing and remediating ground-water contamination.

Borehole-geophysical logging can provide a wealth of information that is critical in gaining a better understanding of subsurface conditions needed for ground-water and environmental studies of open and cased boreholes. It is beneficial to the engineer to know that geophysical logs provide unbiased continuous and in-situ data and generally sample a larger volume than drilling samples, with tremendous vertical resolution.

When combined with driller’s logs and geological sampling, the integration of borehole-geophysical logging along with water-quality sampling will provide a more complete picture, whether the objective is to develop a water-supply well or remediate a contaminated aquifer.



Services Offered

Open Hole Well Logging

TeaCo provides calibrated borehole geophysical well logging services on open holes that provide our clients an objective, repeatable, continuous profile with depth of geologic materials and their associated fluid properties. As the tool is raised through the borehole, data is continually collected and displayed in real time. This allows professionals to make immediate interpretations and decisions with regard to location and attributes of geological formations. The data is easily archived for later study and analysis.

TeaCo has a registered professional geologist on staff with over 25 years of experience in borehole geophysics in the State of Mississippi. This service is provided to those in the water well, environmental, and geotechnical industries.

Cased Hole Well Logging

TeaCo provides calibrated borehole geophysical well logging services on cased holes as well that provide our clients an objective, repeatable, continuous profile with depth of geologic materials and their associated fluid properties. This information is collected once a well is completed and is read through the well casing or screens. These services allow associated professionals the ability to enter the cased wells to evaluate well integrity prior to coming online and to reenter older wells to evaluate conditions.
