Reservoir engineering comprehensive analysis technology |
Reservoir numerical simulation and deep analysis technology |
Reservoir diagnosis and stimulation measure selection technology |
With experiences gained during the practice of technologies such as seismic inversion reservoir prediction, logging data interpretation, reservoir parameter evaluation, sedimentary microfacies analysis and dividing, and reservoir 3D geological modeling, we have established detailed reservoir description technology integrating seismic, logging and geology information, providing solid supporting for the implementation of oil and gas field stimulation and production stabilization technology.
More than 20 detailed reservoir description and comprehensive geological research projects have been completed.
Based on modern reservoir engineering theories, with lessons learned during the practice of pre-development reservoir evaluation, oil and gas field development planning and workflow optimization, remaining oil distribution prediction, reservoir dynamics analysis and oil and gas field adjustment, we have established the reservoir engineering comprehensive analysis technology serving oil and gas field development and adjustment.
More than 40 oil and gas field development and adjustment projects have been completed.
Based on modern flow dynamics theories, with the help of black oil and component models, we provide technical support for the implementation of production increasing and stabilization production using numerical simulation technologies for conventional oil and gas reservoir, heavy oil thermal recovery, low permeability fracturing, reservoir chemical flooding and unconventional oil and gas.
More than 80 numerical simulation projects of heavy oil thermal recovery, low permeability fracturing and high water cut profile control and flooding have been completed.
The development of oil and water well diagnosis, stimulation measure selection and suitability analysis, geological & reservoir programme development, stimulation evaluation technologies has facilitated the integration of geological & reservoir analysis and engineering technologies, providing customized solutions to problems during oilfield development and production.
Our diagnosis and decision making technologies has been applied to more than 1,000 wells.
