System and method for combining curves in oilfield drilling and production operations

Abstract

A system and method for processing and combining data from multiple curves or data-sets in oil field operations based upon a common index. The multiple input curves are combined to form an input vector. The input vector is aligned on the common index, without any values in the curve or data-set being changed. The input vector is then processed to ensure that all curves have values for all index values by interpolation. The input vector may be further processed to create a fixed step increment. An output vector is formed by operation of a set of formulas on the interpolated input vector.
