We provide well logging services to evaluate subsurface geological and hydrogeological conditions within boreholes and water wells. Our investigations involve recording electrical, geological, and physical properties using advanced logging tools to identify aquifers, fractures, lithology variations, seepage zones, and groundwater-bearing formations. We implement methods such as SP logging, resistivity logging, gamma logging, caliper logging, and temperature logging for groundwater exploration, borewell assessment, tunnel investigations, dam safety studies, and geotechnical projects. These surveys help improve drilling accuracy, aquifer characterization, and engineering decision-making through detailed subsurface interpretation.
We conduct Electrical Resistivity Tomography (ERT) surveys to obtain detailed subsurface resistivity imaging for groundwater, geological, and geotechnical investigations. The method is implemented by injecting electrical current into the ground through multiple electrodes and measuring resistivity variations to identify aquifers, fractures, weathered zones, seepage paths, cavities, and weak rock formations. Our ERT surveys provide high-resolution subsurface profiles widely used in groundwater exploration, dam and tunnel investigations, mining studies, and environmental assessments.
A pump test is a hydrogeological investigation conducted to evaluate aquifer characteristics, borewell yield, groundwater potential, transmissivity, storativity, and sustainable pumping capacity. The test helps determine the performance and long-term viability of groundwater extraction systems.
The investigation involves controlled pumping and continuous groundwater level monitoring using electronic water level indicators to analyze aquifer performance and groundwater behavior.
Common interpretation methods include:
Before pumping begins, the initial groundwater level is measured using a water level indicator.
The pump is operated at a constant discharge rate while flow measurements are recorded periodically.
Groundwater level changes are recorded using the water level indicator at regular intervals such as:
After pumping stops, groundwater level recovery is monitored over time to evaluate aquifer recharge characteristics.
We conduct Self Potential (SP) surveys as a passive geophysical method to detect natural electrical potential variations associated with groundwater movement in the subsurface. The method is implemented using non-polarizable electrodes and high-sensitivity measurements to identify fractures, seepage paths, weathered zones, and groundwater flow channels. Our SP investigations are widely used for groundwater exploration, dam seepage studies, tunnel investigations, and fracture zone mapping, often integrated with VES and ERT surveys for improved subsurface interpretation and accurate borewell targeting.
We conduct Vertical Electrical Sounding (VES) surveys using the Schlumberger electrode configuration to investigate subsurface resistivity variations. The method is implemented by injecting electrical current into the ground and measuring the resulting potential difference to identify aquifers, weathered zones, fractures, and hard rock formations. Our surveys provide reliable data for groundwater exploration, borewell siting, aquifer depth estimation, and geological investigations through accurate field measurements and interpretation.
