EURs & Type Curves


At Canadian Discovery Ltd. (CDL), we’re focused on results. We develop and maintain an extensive suite of play-based type curves and supporting algorithms. CDL’s robust, regionally based estimated ultimate recoveries (EURs) enable clients to better evaluate opportunities and make decisions.

What We Offer

CDL currently delivers Western Canada EURs, along with supporting type curves for horizontal wells, through our Catalyst application. These EURs support our M&A services and figure prominently in our reports. CDL’s proprietary EUR methodology is also transferable to other basins.

Currently, type curves and EURs are commercially available for the Bakken, Cardium, Montney and Viking resource plays. All other Western Canada resource play type curves and calculated EURs will be available in Q3 2016.

What Makes Us Different

While EURs from production declines are readily available, they do not work for resource play wells. Conversely, type curve-derived EURs, such as those from independent engineering firms, are not typically available commercially because they incorporate confidential inputs.

CDL is the only independent third party to offer a suite of type curve-derived EURs for all of Western Canada. We follow the SPEE/USGS methodology for calculating EURs for multi-stage fracs in unconventional reservoirs.

For horizontal wells we:

  • Map and maintain geological plays across Western Canada in order to group wells in similar environments based on factors such as facies, temperature and pressure.
  • Develop and maintain a suite of probabilistic type curves (PTC–P10, P20 … P90) for every play, to which individual wells are then fitted.
  • Account for by-products (solution gas, free liquids recovery, deep or shallow cut natural gas liquid yields) by leveraging our proprietary Gas Liquids & Light Oil Atlas and conducting additional research.

For vertical and deviated wells, we generate EURs using our proprietary algorithms for production decline.
