Dr. Scott Mildren, Solution Lead - Geomechanics Centre of Excellence

The importance of geomechanics in the productivity of unconventional plays is becoming more widely accepted.  It is known to directly control rock behaviour and consequently influence drilling and production activities. However, geomechanical models are inherently uncertain by their nature requiring a wide range of data inputs and calibrations.

In the past we have relied on relationships between geomechanical properties such as Young's Modulus, Poisson's Ratio, Brittleness Index, and TOC in place of complete geomechanical models themselves.  Here we present an improved workflow and property model that addresses geomechanical model accuracy to predict pre-drill rock behaviour directly.

This presentation reviews some of the fundamental concepts underlying this approach to geomechanical modelling for unconventional plays and illustrates, with examples, where the accuracy of direct geomechanical behaviour prediction can benefit unconventional operations. 



Scott completed his PhD at the University of Adelaide Australia in 1997 and took up a position as structural geologist and geomechanicist with Z&S (Asia) Ltd. (now Baker Atlas). From 1999 until 2003 he was among the academic staff at the Australian School of Petroleum and the National Centre for Petroleum Geology and Geophysics researching various geomechanical related issues such as, fault and cap rock seal integrity, fractured reservoirs, wellbore stability and trap risk.

In 2001 Scott co-founded JRS Petroleum Research Pty Ltd providing geomechanical and image log services to the petroleum industry in the Asia Pacific region. JRS was purchased by Ikon Science in 2012 to become Ikon’s global Geomechanics group.  Scott now spends his time between Australia and the U.S. as Solutions Lead for Ikon’s Geomechanical Centre of Excellence. Scott is a member of AAPG, ASEG, EAGE, PESA, SEG, SPE and SPWLA.
