Surface geo Physics includes
Microgravity surveying is a geophysical mapping technique that detects areas of contrasting density by measuring localized variations in the Earth's gravitational field. Our technical team is able to map the density contrast, detect weak zones, predict cavities and also provide a more complete picture of the subsurface by using microgravity in conjunction with other geophysical techniques.
EM instruments are commonly used during environmental investigations to measure the ground conductivity. Our expert team is experienced of mapping ground conductivity for environmental and archaeological purposes.
A Vertical electrical sounding (VES) is a 1D resistivity method for investigation of a geological medium, based on the estimation of the electrical resistivity. We are experienced in performing VES with different configurations and provide information of the subsurface and corrosivity index especially in plants.
MASW is used for highlighting the areas of anomalous response associated with adverse subsurface conditions that may contain cavities or karst structures, soft material and soil. Our multi-geode system, which consist of land streamers with various geophone spacing and various in-house seismic sources, offers a highly customizable solution to meet any project requirement.
Seismic Refraction is extensively used for mapping subsurface geologic conditions including depth to bedrock, water table, stratigraphy, lithology and structure or all of these. Our technical team is well equipped to do P-wave refraction to cater different project requirement.
ERT is used to map geologic features such as lithology, structure, fractures, and stratigraphy; hydrologic features such as depth to water table, depth to aquitard, and groundwater salinity; and to delineate groundwater contaminants. We are experienced in performing ERT in a variety of challenging environments, ranging from inter-tidal zones to arid and sandy terrains.
he ReMi method is a seismic surface wave method that uses ambient noise and surface waves. Since it thrives in noisy environments the ReMi method is ideal for shear wave profiling in urban environments where seismic refraction is precluded because of large amounts of ambient noise. We have expertise to conduct the survey in urban areas with proper traffic management.
GPR is used for highlighting the adverse condition in shallow depth and mainly for utility detection. We have expertise in utility detection and archaeological mapping using our highly portable GPR system.

Borehole geo Physics includes
Deviation probe uses a three-axis magnetometer and a dual tilt sensor to provide azimuth and inclination of the borehole respectively. We use this data to provide the geometry of the borehole.
The PS logging system consists of a seismic source and two receivers built into a single probe. Our experts use PS Suspension logger to measure both the P and S waves velocities in water-filled borehole by using a piezoelectric source attached at the bottom of the tool. By using P and S wave velocities, other elastic moduli could be derived for the engineering designing purposes.
Various types of logging probes are used in borehole for different purposes i.e., diameter of borehole, natural gamma ray, fractures with orientation and borehole condition, different electrical parameters, temperature and conductivity of water etc. We are equipped to provide any engineering parameters for various applications and provide better geological analysis by combining our various tools based on project requirement up to 1000m (subject to pressure limitations of the tools)
Downhole Seismic is used for 1D profiling of p and s wave velocity in cased borehole with annular grout. From downhole results we can extract the engineering parameters. Our experts can compute the dynamic elastic moduli of the terrain by measuring the velocity of the primary and secondary waves along the borehole of up to 100m depth.
Crosshole seismic is used for 1D profiling of velocity in set of two or three boreholes for precise assessment of different engineering parameters. Our experts can compute the dynamic elastic moduli of the terrain by measuring the velocity of the primary and secondary waves along the borehole of up to 100m depth and also detect the existence of zones with "velocity anomalies" between boreholes.
Crosshole tomography is done by using one borehole as receiver and other as source borehole. Our team is able to image the lithology variation, extension of cavity or weak zone and to assess the presence of cement or grout material between two boreholes.

The basis of the method is that current is injected into the ground through electrodes, a resulting potential is measured which allows for the calculation of resistivity. Electrical resistivity tomography is one of the techniques available for studying freshwater and saltwater aquifers. We use ERT to provide a common image of the freshwater/saltwater interface, which can be used to manage coastal aquifers.
