IntroductionWith the foundation laid by oilfield dynamic and remaining oil distribution analysis, we have developed technologies such as target well/layer selection, target well potential evaluation, engineering design optimization, profile control effect prediction and specialized reservoir simulation and development planning, allowing a scientific, swift and accurate matching of enhance oil recovery measures and customization on oil field adjustment scheme planning. List of Technologies
ApplicationsOver the past ten years, more than 2,000 single-well measures and more than 40 large to medium-size oilfield comprehensive research projects have been completed. The engineering design optimization technology has been using for offshore innerlayer CO2 profile control on over 100 wells. The dominant flow channel characterization technology has been applied to more than 40 well groups for offshore profile control. The potential evaluation technology has successfully lead and support the water control on over 40 wells and FSG sand control application on more than 10 wells, allowing a cumulative oil increase of 110000m3.
