 This will be a sold-out event, with limited seating!! RSVP early to guarantee your attendance!!!!!

Geomechanical Facies Model for the Wolfcamp Formation 

presented by

Valeri  Shelokov


This topic will review the relationship between Poisson’s Ratio, Young’s Modulus and Lithology to determine the formations capability to fracture (fracture facies). Integrating this facies with the core data allows to observe a geo-mechanical properties contrast between the baffle layers and the frac-able layers. The final product use a Triple combo log (Resistivity/ Density/ Neutron) to create the geo-mechanical facies model and synthetic Poisson’s Ratio, Young’s Modulus.

The results of this model improved understanding of the rock geo-mechanical properties of Wolfcamp formation across the basin. Geomechanical Facies analysis becomes a valuable tool for the target landing interval and fracture modeling.

 Speaker Biography:

Valeri Graduated from Tomsk State University (Russia) in 1986 and from Heriot-Watt University in 2003. He worked for YUKOS Company in Russia and for MARATHON Oil, with experience in both unconventional resource plays and conventional reservoirs in domestic and international basins in USA, Norway, Poland, Hungary, Romania, Ukraine, and Russia. Within the U.S. he has developed consistent petrophysical models for a variety of domestic resource plays like the Midland and Delaware basins, and the Eagle Ford, Haynesville, Marcellus, Woodford and Bakken formations.  Since 2011 he has been working with Pioneer Natural Resources, mostly on Permian basin.
