Geomodeling: Challenges & Quality Control

Geomodeling: Challenges & Quality Control

Tuesday 21st February 2017

Social gathering starts at 5:00PM

Presentation starts at 5:30PM

The architecture of carbonate reservoirs is very complex because heterogeneities are present at multiple scales and this makes their incorporation into 3D geo-cellular models a very challenging task. Robust reservoir characterization and modelling requires the proper understanding of the spatial and vertical distribution of these heterogeneities in the inter-well region at a grid (cell) scale, so that the correct assessment of the areal and vertical sweep efficiency and, therefore, the calculation of the recovery factor can be done. The focus of Jorge’s talk is a high level overview of the main challenges in 3D modelling of carbonate reservoirs and the QA/AC control tools in place to verify and validate the quality of such models. Jorge will emphasize on the need for inter-disciplinary synergy between geoscientists, petrophysicists and reservoir engineers, to ensure the properties of the static model are reconciled with dynamic data for a sound history match and subsequent reservoir forecast. The talk will show workflows and examples covering from the construction of the structural framework to the water saturation modelling, addressing sequence stratigraphic framework, reservoir rock typing and petrophysical modelling of porosity and permeability. .

Jorge has a broad technical experience in geosciences and petroleum engineering covering both exploration and production aspects of the oil and gas industry. With over 30 years of experience in the industry and 6 years in academia, his expertise resides in the areas of carbonate reservoir characterization and geo-engineering (integrating static and dynamic data to build geocellular models) to optimize field development plans, predict reservoir performance and assess resources and reserves. Having worked in projects in different countries (Portugal, Qatar, Oman, UK, Libya, Austria, Abu Dhabi) and for various operating companies (PARTEX, Qatar Petroleum, ADCO), service companies (PSC, HOT Engineering) and academia (The Petroleum Institute), the majority of his experience has been with large Jurassic and Cretaceous carbonate fields of the Middle East (Qatar and Abu Dhabi). Jorge initiated his career with BP Minerals and EDMA as Junior Geologist, occupying subsequently, senior positions such as Senior Geologist, Team Leader (PARTEX, Qatar Petroleum), Head of Lab & Special Studies (Qatar Petroleum), GeoScience Coordinator, Team Leader (ADCO, PARTEX), Chief Reservoir Geologist (HOT Engineering), GeoScience Expert (ADCO), PARTEX Chair Professor and A/ Senior Vice President R&D (The Petroleum Institute). Jorge is currently ADNOC’s expert in geomodelling and Adjunct Professor at the Petroleum Institute. Jorge is the author of three books (ISBN 978-989-20-3778-3, ISBN 978-953-51-0825-2, ISBN 978-972-31-1228-3), and has published several SPE papers and made various presentations at international conferences as keynote speaker. He has been the recipient of several regional and international awards (industry and academia) and recognized for two gas discoveries in Qatar. He has a BSc and MSc in Geology from Oporto University (Portugal) and a MEng and PhD in Petroleum Engineering from Heriot-Watt University (UK). He is member of the Society of Petroleum Engineers (SPE); American Association of Petroleum Geologists (AAPG); European Association of Geoscientists and Engineers (EAGE) and Emirates Society of Geoscience (ESG). He is the father of two, a scuba diver and keen fisherman and occupies his free time with agricultural eco-tourism in Portugal. .
