Private Enterprise “Poltava Geophysical Operations Company” provides a full range of geophysical logging services using modern high-precision instruments and advanced data processing technologies, enabling the acquisition of detailed information on the geological structure of the section and the reservoir properties of formations.
Our solutions ensure accurate determination of lithology, porosity, permeability, and the saturation characteristics of formations, as well as the identification of prospective reservoir intervals and refinement of productive horizon boundaries. The obtained data form the basis for effective technological decisions regarding well testing, perforation, and further field development.
With the use of modern modular geophysical equipment, operations can be performed under challenging downhole thermobaric conditions — up to 175 °C and pressures up to 140 MPa, allowing investigations to be carried out in deep and high-temperature wells.
Thanks to the application of advanced modular logging systems and the extensive experience of our specialists, we ensure high accuracy of measurements, prompt execution of operations, and reliable results that contribute to improving the efficiency of oil and gas field development.
