With the foundation laid by our comprehensive geological & reservoir analysis, the Research Institution of the Production Optimization Division has develop integrated geo-engineering technology and other reservoir-engineering-related technologies, consolidating the leading and supporting role of G&R technologies in the fields of well completion, stimulation and enhanced oil recovery, and is able to provide the whole life cycle technical services during the exploration, development and production of oilfield. Through the development of three major series of technologies that include oil & gas resource evaluation, oil & gas development decision making and reservoir diagnosis and treatment selection, we have achieved the synergistic functioning of geological & reservoir analysis and engineering, and can provide comprehensive, multi-level and integrated solutions targeting the problem and need during the development and production of.oilfields. TeamOur team is composed of 89 geological reservoir technicians, including 2 experts of the group company affiliated unit. Core Technologyoil & gas resource evaluation oil & gas development decision making reservoir diagnosis and treatment selection Reservoir description Geological modeling SoftwareWe have independently constructed a geological & reservoir decision making platform integrated with multiple self-developed softwares, covering the complete chain of geological & reservoir services including enhanced oil recovery, reservoir stimulation, heavy oil development, well completion and sand control, monitoring and interpretation Experimental CapabilitiesThe digital core analysis technology allows quantitative characterization of nano- to micron-scale pores and further fluid flow simulations. We are also capable of performing large-scale physical experiments on oil-gas-water triple phase fluid flow. |
