PT Gealogic Survey Provices offers exploration surveys which are related to energy (oil, gas, geothermal), minerals and metal, groundwater, civil engineering and geotechnical problems. We provide several survey methods i.e. geo-electrical, geochemical and geophysics followed by drilling service.
We offer a Non-seismic survey for the geophysics survey, like the magneto telluric method, Time Domain EM, Induced Polarization (IP) and a combination of the above methods using the best-known Phoenix Geophysics equipment. Magneto telluric (MT) is the most commonly used technique, from the natural signal of the earth’s magnetic field; MT derives a reistivity – VS – Depth image of the subsurface. Magneto telluric (MT) technique is used in the development and application for geothermal resources exploration. It acquires quality data and can pinpoint the location of geothermal sources. For the Oil and Gas Exploration, the induced Polarization (IP) methods, achieves drilling success until 73% (based on 65 wells).
At a basic level of interpretations, resistively is correlated with different rock types. High - velocity layer are typically highly resistive, where as sediments – porous and permeable – are much less resistive. While high – velocity layers are an acoustic barrier, their electrical resistivity means the magnetic signal passes through almost unimpeded, allowing MT to see deep beneath these layers. MT Data provides both dimensionality and directionality indicators, adding more detail to structural and stratigraphic interpretation.
On the other hand, it has made valuable contributions in refining geologic models, reducing exploration risk, and improving production monitoring.
Drilling services are carried out for water wells, construction pilling and soil sampling using Longyear, YBM and Koken. We also conduct wire line coring system mainly in the field of mining surveys, oil and gas surveys, water well drilling, grouting and geothermal surveys.
Our team is also very experienced in drilling rigs, fluids, mud logging, H2S monitoring, wire line logging, log processing, cementing, stimulation and testing operations, complete with an international quality certification. We provide our costumers excellent quality and services.

GAMMA RAY SPECTROMETER SYSTEM
The Radiation Solutions RS-500 Gamma Ray Spectrometer is interfaced to a RSX-4 NaI (Tl) crystal detector pack with a total volume of 16.8 liter (1,024 cubic inches) which provide high resolution spectral information from 0.3 MeV to 3.0 MeV. In addition, the five primary regions of interest, Total Count, Potassium, Uranium, Thorium and Cosmic are recorded. The detector packs embody the latest techniques whereby the elimination of “dead time” in the counting process yields up to 20% more counts over competing systems. Superior calibration facilities include the visual real time monitoring of full spectrum data and in flight monitoring of gain drift relative to the selected isotope window, ensure that long term data quality is maintained. |
