..., it is necessary to determine the water injection adjustment to achieve better effects. Random forest algorithm (RF) is applied to determine the allocation type for wells and intervals, such as strengthened, controlled, and unaltered wells and intervals. Subsequently, the multi-objective simulated annealing...

... Abstract In this work, we adopted the adjustment and control technology of fire flooding in block S which is a common heavy oil multi-layer reservoir. We aim to tackle the problems of large inter-layer utilization differences and uneven advance of plane fire line after areal fire flooding...

...-matching standpoint compared to a conventional workflow where well-level adjustments may be made on one well at a time. In QGC, a model with an improved well-level match is desired as the resulting well forecast will enable decisions on a well-level to be made more confidently, such as the prioritization...

... monitoring and control of production wells. By developing a downhole production parameter monitoring and CPU management system, acquisition of downhole pressure, flow and temperature data, control of flow control valve opening, and saving of historical test and adjustment data into downhole system can...

... mechanism inferred from laboratory evaluation such as wettability alteration, surfactant retention, interfacial tension reduction and improvement of mobility control due to lower oil-surfactant emulsion viscosity. These parameters are initially perceived from laboratory result, upscaling and adjustment...

... Abstract Polymer flooding has been improved an effective way for EOR in China. Comparing with waterflooding, zonal pressure and flowrate change much larger for polymerflooding duo to its high viscosity. Reservoir engineer are required to adjust flow allocation scheme frequently when pressure...

... meet the need of more than seven-layer subdivision because of small distance between regulators, thin interlayer, big releasing force of tubing and low efficiency in zonal flowrate adjustment. To solve this problem, we developed a step-by-step type packer which was released by lifting. The release...
