Building a Regional 3-D Geologic Model of the Paleozoic Bedrock of Southern Ontario - Terry Carter

Energy Prospectors Expo (EPEX 2018) - Ontario Petroleum Institute 56th Conference http://epex.io Building a Regional 3-D Geologic Model of the Paleozoic Bedrock of Southern Ontario - WORKSHOP Presented by Terry Carter, Consulting Geologist, Carter Geologic A regional 3-D geological model of the Paleozoic bedrock of southern Ontario is under development, for completion in late 2018. The model encompasses the entire Phanerozoic succession of southern Ontario (110,000 km2 ), comprised of up to 1,400 metres of sedimentary strata straddling regional arches/forebulge zones separating the Appalachian Foreland Basin from the Laurentian craton and Michigan Structural Basin. This ambitious initiative provides an unprecedented regional 3-D perspective and digital framework to support investigations and decision-making related to resource exploration, hydrogeological/environmental investigation, education, resource management and land-use planning. It is amenable to numeric modelling and provides regional context for site-specific investigations. Model construction is guided by an updated regional lithostratigraphic chart, and utilizes Leapfrog® Hydro - an implicit modelling application. Layers representing 58 formations are constructed using top-bottom formation depths from 20,221 borehole records in Ontario’s public petroleum well database (www.ogsrlibrary.com), supplemented by Ontario Geological Survey (OGS) deep boreholes. An OGS digital bedrock topography surface is combined with revised subcrop geology to assemble a grid of 3-D points that approximate the subcrop surface of each formation, and together with digitized 3-D surface polyline and point constraints, are used to better align the modelled layers. The modern topographic surface is integrated using SRTM DEM data, NOAA lake bathymetry and Canadian Hydrographic data for smaller lakes. Manual editing has been critical to resolving inaccurate thickness extrapolations, gaps in layers, missing/inaccurate formation depth data, obsolete/inconsistent stratigraphic assignments, anomalous outliers, and layer truncation issues at the cuesta/escarpment margins. Model development is an iterative cycle of interim modelling, expert geological appraisal, and editing of geological data using geophysical logs, drill cuttings/core resulting in a revised dataset and improvements to the petroleum well database. Data integrity and model construction have improved such that the current model (version 6) provides a geologically robust representation of regional bedrock geology Watch more from EPEX 2018:    • EPEX 2018   ============ What is EPEX? ============ EPEX highlights the multifaceted nature of Ontario’s oil, natural gas and salt Industries and how they fit into Ontario’s energy landscape. EPEX identifies opportunities to help other energy sectors. After all, we’re all doing the same thing but in different ways -- and that is why the Ontario Petroleum Institute (OPI) and OGSR Library wanted to bring everyone together. Each one of you is an important collaborator in this conference and your participation highlights the multidimensionality of our energy sector in Ontario. EPEX is about more than prospects – it’s about exploring! ================ EPEX 2018 BLOCKS BLOCK 1 - ENERGY STORAGE BLOCK 2 - ENVIRONMENT AND RISK MANAGEMENT BLOCK 3 - HYDROCARBONS ================ Get the full EPEX 2018 program: http://epex.io/wp-content/uploads/201...
