Geological and Hydrogeological Studies
SUPRA has a long and successful record of working with consultant, planners, engineers, developers and expert working in multidiscipline field. We provide consultancy services for geological and hydrogeological studies, groundwater availability studies and management, water resources management, aquifer mapping and modeling, well-field designs, groundwater monitoring, aquifer studies, borehole condition assessment, groundwater recharge, groundwater quality assessment, determination of groundwater abstraction patterns and borehole density etc.
The search for groundwater begins with a review of existing published literature, research, and well logs, which are gathered from various sources. Topographic, Geological, and Hydrogeological maps are studied and compared with existing information to select a specific drilling consultancy, management, and planning. SUPRA uses integrated step by step approach to provide its clients the important service of assesing groundwater depth, yields, and suitability prior to costly drilling.
Integrated Geophysical Study
SUPRA conducts integrated geophysical studies and survey. It consist of determination of aquifer characteristics and types, aquifer size/location and depth, groundwater quality and hydrochemistry, abstraction patterns and aquifer depletion, groundwater recharge, saline water intrusion, aquifer contamination etc.
- ERS: Through Electrical resistivity we can measure the electrical properties of the subsurface, mapping the subsurface for aquifer prospects.
- IP: Induced polarization is a geophysical imaging technique used to identify the electrical chargeability of subsurface materials. Induced Polarization method is ideal for Mineral Exploration purposes especially ore.
- VES: Vertical electrical sounding (VES) is a 1D resistivity method that provides deep information of the subsurface. VES is ideal for detection of subsurface anomalies and conditions such as caving, faulting, stratigraphic structures,
- GPR: Ground-penetrating radar (GPR) is a tool that uses radar pulses to image the subsurface. GPR is ideal for shallow depths (1m-30m) and small covered areas for detection of subsurface anomalies and conditions such as caving, faulting, stratigraphic structures, etc. The applications of GPR make it ideal for Geo- Technical sectors.
- CaliperLog: Through Caliper logging we provide a continuous measurement of the size and shape of a borehole along its depth. The measurements that are recorded can be an important indicator of cave or shale swelling in the borehole, which can affect the overall result and working of the bore.
- Gamma Ray Log: Through Gamma ray logging we can measure naturally occurring gamma radiation to characterize the rock or sediment in a borehole.
- Spontaneous Potential Log: Spontaneous potentials (self-potential) are measured down boreholes for formation evaluation.
SUPRA are able to advise on a range of topographic survey matters, including the best survey option for your site, details on topographic survey cost and various other key questions. A topographical survey is an accurate depiction of a site (property, area of land, defined boundary) which is scaled and detailed according to the spatial considerations and is the summary of the on-site data capture processes. This type of topographical survey is a detailed process which requires the insight of topological professionals to ensure the accuracy of all of the reports provided.
SUPRA provides a wide range of services related to geological and hydrogeological services
We are capable to perform consultancy in geological, geotechnical, hydrogeological and geophysical, and topographic survey to examine exploration, exploitation and construction needs. All the methods are in accordance to national standards and procedures.
Our services include:
- Desk Study using secondary data and brief visit to location.
- Geophysical Survey using electrical, magnet and seismic wave to describe underground condition.
- Geological Mapping to understand historical topography and rock formation and potential geological resources.
- Hydrogeological Mapping and Analysis to determine optimal location of water supply by identifying water spring and aquifer layer.
- Geotechnical Analysis and Recommendation to integrate geodetic, geological, drilling and laboratory data to identify bearing capacity of a construction area
