Abstract
This paper proposes a new response surface building method for
accurately estimating reservoir flow performance. Usually, due to
time consuming calculation, the allowed number of flow simulations
does not provide enough information for capturing the curvature and
non-linearities in the flow response surface. The method combines
classical flow simulation results with secondary information
provided by fast flow simulation such as the time-of-flight
connectivity. For this purpose, the method is based on the discrete
smooth interpolation algorithm which has the advantages to be (1)
data exact, (2) unbiased by the choice of an initial model, (3)
flexible, so complex response surface can be modeled, and (4) can
handle in a unified and simple framework heterogeneous data. A
modified version of the SPE 10th Benchmark Model has been used to
investigate the accuracy of the generated response surface, and
monte-carlo sampling was carried out to measure the impact of the
method on uncertainty assessment. Results show that the proposed
method (1) works accurately and efficiently in modeling the repones
non-linearities and (2) provides a satisfactory P10, P50 and P90
values for uncertainty assessment.
