SUPPRESSING OSCILLATIONS DUE TO PATTERN SWITCHING IN LOW DRAWDOWN WELLS

摘要

From a simulation engine simulating the field operation, simulation variable values corresponding to grid cells are obtained. The grid cells represent at least a portion of the field for simulating the field operation. The simulation variable values are analyzed to generate a scaling factor and adjusted according to the scaling factor to generate adjusted simulation variable values. The scaling factor controls intermediate result deviation between computation iterations of simulating the field operation. Using the simulation engine, a simulation result is generated based at least on the adjusted simulation variable values. A field operation is performed based on the simulation result.
