    Abstract

    A new algorithm based on B-splines was proposed to consider the rate measurement error during pressure deconvolution. Several methods were provided to determine the actual rates for each flow period, which can be utilized to determine the actual pressure response in turn. The results show that unit-rate pressure response with 10% rate error agrees well with the true results, which is much better than that from ILK model. The new algorithm can overcome the effect of rate measurement error on the pressure response.
