Some of the key technology challenges confronting the Company are modeling the complex oil and gas basins, improving accuracy and efficiency of oil and gas potential predictions based on seismic data, and improving exploratory well testing efficiency.

radiation modeling

The Science and Technology Center’s team works on projects designed to improve geological exploration processes at all levels: from the reservoir and formation to regional studies and simulation of oil and gas basins spanning several regions.

Continuous improvement of technologies will enable the Company to develop its competences in operating the resource base with complex structure basins, harvest incremental recoverable reserves and cut future drilling costs.

Following this concept, Gazprom Neft applies radial modeling to plan and green technologies to implement seismic surveys. Special projects for low-frequency processing and high-resolution spectral decomposition of acoustic signals are undertaken to improve accuracy and objectivity of seismic data interpretation. This work results in software products built around the existing regional geological data and historical seismic data, which help optimize seismic survey plans and improve the acquired data processing and interpretation quality. Gazprom Neft is heavily engaged in the technology optimization and automation process aimed at selecting the most suitable sets of exploratory well tests and core analysis, with particular focus on database building efforts.

To study large-size areas, development of non-seismic exploration methods was initiated. In early stages of exploration projects when information about the asset is very limited, the use of these methods will allow the oil company to make investment decisions. The advantage of non-seismic methods is that field studies performed with these methods are relatively inexpensive. The cost of most of them does not exceed 10% of the cost of seismic exploration with the same scale and scope of survey. Five areas are being developed in this context: gravity exploration, magnetic exploration, electrical exploration, areal geochemical survey, and geomorphological analysis (airborne/satellite geological surveys).

Another important area to be developed is geochemistry. Along with the regional level tasks, geochemistry helps geologists analyze geological structure of reservoirs and improve petroleum production efficiency. For assets with hard-to-recover and unconventional reserves, geochemistry is able to determine saturation, estimate reserves and predict changes in petroleum properties with a high degree of reliability. In this area, three main subjects are being worked on: hydrocarbon systems analysis, reserves recovery control methods, and studies of unconventional hydrocarbon systems.
