Study of Drillability Evaluation in Deep Formations Using the Kriging Interpolation Method

Abstract

During development of production processes in deep formations by means of wells placed in lower productive intervals, it is specifically such formations that have gradually become the major challenge in oil production. Due to the considerable depths and the combination of complex properties of the formations, in order for formulate a rational development program for the formations we need comprehensive understanding of their drillability and distribution in the specified region. In this paper; in order to provide such geological information, based on laboratory core experiments we have established the drillability of sections of the formation in a specified region by interpolation of support vectors by the kriging method.
