Interpretation of pressure built-up curves on the basis of analysis of bottomhole pressure detrministic moments
Some new method for processing of pressure built-up curves in a heterogeneous layer consisting of any number of zonal-homogeneous sections is proposed. The obtained representations served the basis for development of the procedure of identification of subsequent permeability coefficients and boundaries of homogeneity zones for bottomhole pressure deterministic moments at each sector of a layer homogeneity. Savitsky – Golay method of numerical differentiation is applied for identification of a layer homogeneity zones.
