Mining Well Logging

Mining operations require reliable subsurface data and contractors who can work safely in regulated environments. Statewide Well Surveys LLC provides geophysical well logging for dewatering wells, exploration boreholes, and monitoring programs at mining sites throughout California, Arizona, Nevada, and the broader Western United States.

Tools & Techniques

Mining Logging Services

SWS logs dewatering, exploration, and geotechnical boreholes for mining operations. Select a service to see what it covers, what it tells you, and when it is used.

Exploration Borehole Logging

Open-hole geophysical logging run in exploration and coreholes to characterize the geology penetrated during a mining program.

What it tells you

Lithology, structure, and formation properties along the borehole.

When to use it

On exploration and delineation drilling, to add downhole data to core and cuttings.

Dewatering Well Surveys

Logging and flow surveys on the dewatering wells that manage groundwater around pits and underground workings.

What it tells you

Potential producing zones, relative flow contribution, and information about dewatering-well performance.

When to use it

To design, verify, and troubleshoot mine dewatering wells.

Deviation / Verticality Surveys

Surveys that measure how far a borehole has drifted from vertical, along with its measured trajectory.

What it tells you

Actual borehole trajectory and verticality.

When to use it

Where straightness matters for pumps, casing, or regulatory and geotechnical requirements.

Gamma-Ray & Resistivity

Gamma-ray and resistivity logs read lithology and formation properties, forming the backbone of geologic correlation.

What it tells you

Lithologic changes, formation boundaries, resistivity characteristics, and potential water-bearing intervals.

When to use it

For formation evaluation, correlation, and mapping where appropriate.

Caliper, Temperature & Fluid

Caliper measures changes in borehole diameter while temperature and fluid logs read the borehole fluid column.

What it tells you

Borehole condition and where fluid and temperature change.

When to use it

To assess hole quality and support flow and integrity analysis.

Records & Safe Operations

Data is delivered as LAS files for geotechnical records, and all field work is carried out by MSHA-trained crews under site safety requirements.

What it tells you

Documented, auditable downhole data collected under mine-safety compliance.

When to use it

On any regulated mine site where records and MSHA compliance are required.
