The impact of formation damage on overall well productivity or injectivity depends on the magnitude and distribution of the damage. Computational Fluid Dynamics (CFD) simulation provides a means to upscale suitable laboratory test data to quantify the impact of formation damage on well performance, by representing the degree of restriction and the geometry of the damaged zone or zones in a full well simulation. Different magnitudes of damage derived from laboratory test data can be simulated and the impact on overall well performance predicted for different completion environments. This presentation will illustrate some applications of CFD modelling to upscaling of laboratory measured formation damage, and attempt to tackle the issue of the interface between well construction and well deliverability.
Rick Lemanczyk is Principal Petroleum Engineer in Lloyds Register Energy’s Consulting Division, based in Kuala Lumpur, and has a career spanning over 39 years in various aspects of production technology.
After graduating with a D.Phil. in Physical Chemistry from Oxford University, Rick began his oilfield career with Schlumberger from 1977-1992 in a variety of positions: wireline engineer, well stimulation R&D department head and regional laboratory manager. Between 1994 -2006 he worked for Edinburgh Petroleum Services Ltd. (now a Weatherford company), providing technical support, business development, consulting and training in the areas of production optimization, artificial lift, sand management, well stimulation, completion analysis and formation damage. In LR Senergy Rick’s current role is to coordinate the company’s rock properties and production chemistry activity in the Asia Pacific region.
Throughout his oilfield career Rick has conducted many training courses and lectured widely on Production Technology subjects. In 1992-94 he was a Senior Research Fellow at Heriot-Watt University in Edinburgh, and in 2016-17 Adjunct Professor at Heriot-Watt’s Malaysia campus. He was nominated as an SPE Distinguished Lecturer in gas lift optimisation for 2010-2011.
