Geomechanical behaviour is the root of many challenges that impacts drilling operations and field development in unconventional and conventional plays. Where data acquisition permits, retrospective geomechanical analysis provides insight into rock behaviour. However, translating these observations to a predictive model that can help avoid issues and reduce costs remains difficult. Extrapolation of the fundamental properties used to construct geomechanical models can use various techniques that range from simple interpolation to more complex quantitative interpretation workflows depending on the data set available and the project requirements. Although the individual methods applied under each discipline are not innovations of themselves, common practice is to perform the geomechanical analyses sequentially or in parallel with the property modelling. We propose a workflow that reflects the interrelated nature of the inputs and outputs at each step in order to better characterise the reservoir and make predictions of geomechanical behaviour.
Scott is a geologist with 20 years of experience in petroleum geology and geomechanics. He started his career in Perth with Z&S (Asia) Ltd (now Baker Atlas Geoscience) performing geomechanics and image log related analyses following the completion of his PhD in 1997. From 1999 until 2003 Scott returned to academia researching various geomechanical issues such as wellbore stability, fault and cap rock seal integrity and fractured reservoirs at the Australian School of Petroleum. After leaving the University once more, he was one of the original founders of JRS Petroleum Research known for providing geomechanics and image log software and services around Australasia. JRS was purchased by Ikon Science in 2012 to integrate geomechanics with their rock physics and quantitative interpretation offerings and Scott now heads up the European and Middle East operations based out of Adelaide.
