Smoothing of Well Rates in Subsurface Hydrocarbon Reservoir Simulators

Kounchev, O. and Todorov, M. and Georgieva, D. and Simeonov, N. and Kolev, V. (2014) Smoothing of Well Rates in Subsurface Hydrocarbon Reservoir Simulators. [Study Group Report]



A common problem in reservoir simulators is the history matching problem, where a number of wells are operated at a prescribed flow rate, measured by the operator. The data provides input to a simulator which then has to match various other measured quantities, such as pressure drop at wells, movement of saturation fronts, water break-out and other. A common problem is that the input data is very rough and if input directly would cause considerable numerical difficulties, such as excessive Newton iterations to converge or excessively small time-steps.
