UCS Prediction: A New Set of Concepts for Reservoir Geomechanical Modeling

Abstract

Simulation and estimation are based on geostatistics methods; they have been greatly accepted to simulate different features of hydrocarbon reservoirs, so that much software for reservoir simulation work are based on these methods. A good estimator provides not only average errors of estimations but also shows the geostatistical distribution of the estimated errors. Generally, geostatistical estimation is a process that obtains the value of a feature in points with known coordinates, using the value of this feature in other points with known coordinates. This geostatistical estimator is called kriging. Rock strength has an important role in oil production and drilling in hydrocarbon reservoir. Thus, uniaxial compressive strength (UCS) is an efficacious parameter in drilling operation in hydrocarbon reservoir. Here the UCS has been examined and processed by using geostatistical methods for one of the oil fields in southwestern Iran.
