Ideal or Nothing
Topic 1. Studies on Ultra-deep Tight Reservoir Acid Fracturing Treatment Technology Optimization
Led by Dr. Hill and Dr. Zhu, the previous data of acid fracturing treatment for ultra-deep HTHP wells in some oilfield are analyzed to find out existing problems and present optimization design proposals. A number of important discoveries have obtained through the first phase study of the project and the results have been highly recognized by our customers. The second phase study is in the process and it will deepen the preliminary research results. Acid fracturing treatment design will be prepared and applied onsite.
Topic 2. Studies on the Prediction of Fractured Reservoir Double Porosity & Permeability Sidewall Stability
Led by the Dr. Abousleiman, a double porosity & double permeability model is established starting from Geomechanics to cope with wellbore instability problems in drilling and completion processes, and a geomechanical prediction software platform suitable for some oilfield is developed (an international initiative, which has obtained the relevant international patent). The software has been widely used by our customers and it has provided a critical mechanical basis for drilling and completion engineering.
Topic 3. Studies on Residual Oil Distributional Characteristics and Enhanced Recovery Techniques for Some Oilfield
Led by Dr.Wang and Dr.Nasr-El-Din, based on reservoir microscopic imaging techniques, the distribution of remaining oil is described and a targeted displacement experiment is carried out. The type of displacing agent and processing parameters are optimized. It is expected that the oil recovered will be increased by 8-10%.
Topic 4. Studies on HTHP Ultra deep Well Completion String Material Design Criteria
In cooperation with Blade Energy Partners Company, systematic evaluation and model analysis on materials, processes and technology used in ultra-deep well completion design are carried out, and existing problems in material selection and process flows for operation processes are found out. Using the unique technology of Blade, new design methods and design criteria are proposed.
