An Extra 45 Minutes Can Provide a World of Knowledge

SPE Bergen Section would like to invite you to the TechNight with SPE Distinguished Lecturer at Nøsteboden! This is a great chance for you to keep yourself updated on latest technologies in the market and to meet your industry colleagues during the dinner after the presentations. 

1. Distinguished Lecture Abbas Khaksar: Using Advanced Geomechanical Analysis to Define Practical Cut-offs for Sand Management Decisions

This presentation demonstrates how a series of pragmatic cut-offs and decision support charts can be derived for credible sand management and completion selections.  Sanding (or solids production) has multiple adverse effects on well productivity, integrity and can pose safety and environmental hazards. Sanding has a geomechanical root and it can be managed: “avoided; mitigated, controlled or handled”.  An effective sand management strategy starts with the geomechanical characterisation of the target formations and sand production assessments. Once the field-calibrated geomechanical sand production prediction model has been established, using limited data such as a log-derived rock strength profile, decision flowcharts can be developed to assist well engineers for completion and sand control decisions by considering the well-life risk of sanding and borehole instabilities. Such decision charts enable well and production engineers to follow a quick, cost-effective and holistic approach for sanding assessment and completion selection.  This contrasts with alternative methods, which can be either overly simplistic or excessively complex.  Two case studies are presented which cover the development and use of practical cut-offs for real-time sanding assessments and completion selections. In both cases, the methodology has contributed to reduced well costs and alleviated production losses due to sanding and sand control complexities.  

Biography

Abbas Khaksar is a Global Geomechanics Advisor and Subject Matter Expert in sand production prediction and sand management with Baker Hughes. He has 27 years of work experience in petroleum geomechanics working on various projects worldwide.  Before joining Baker Hughes in 2009 (UK, currently in Australia) he worked for Helix RDS (Australia and UK), Geomechanics International-GMI (Asia Pacific Region), University of Adelaide (Australia) and Iran Geological Survey (Iran). Abbas has a PhD in Rock Physics, MSc in Petroleum Geophysics and BSc in Mining Engineering.  He has more than 100 publications and conference presentations on many aspects of oil field geomechanics and sanding evaluation. He is also a short course instructor on reservoir geomechanics applications.
