The impact of noise data on the pressure derivative is characterized by rapid dampening with time,and the after-flow rate for the closure of constant surface rate with constant wellbore storage coefficient is recovered by segmented exponential function in inverted order according to the wellbore material balance equation.Based on this recovered after-flow rate,the early-time radial flow is uncovered by D.Ilk's pressure-rate deconvolution algorithm by removing specified percent of wellbore storage effect,and parameters of reservoir and wellbore are interpreted according to this recovered radial flow.This method is very stable and accurate according to the data test of pressure which contains 30 kPa random noise.

Based on the fact that Schroeter deconvolution needs the initial reservoir pressure as a known condition,and that the reservoir response functions are much sensitive to the exactness of this value,a new method is proposed,based on Levitan method,to deconvolve without the knowledge of true initial reservoir pressure,which is obtained by convolution of rate and unit-rate pressure response from equilibrium time to reference time during deconvolution.Detailed comparisons between the results from this method and those from Levitan method involving true initial reservoir pressure show that it gives correct deconvolution results without initial reservoir pressure,and that the selection of reference time has no impacts on the final results.Moreover,it can deconvolve not only all test data,but also part of individual ones.
