Methodology for Assessing Canadian Oil Sands Recoverable Resources

摘要

Canadian oil sands resources have been developed on a considerable scale,and many oil companies have expanded their business to this new area.How to reasonably evaluate their recoverable resources is the premise for a project success.Taking an oil sands project as an example,recoverable bitumen of a oil sands project was calculated.Firstly,describe the geological characteristics of the area,complete necessary maps.Then prepare basic data for oil sands recoverable resources assessment.Thirdly,determine the distribution model and value of drainage area per well,EUR and drilling success rate,etc,analogized to the surrounding development areas and combined with research of the contract area.Finally,run the Monte Carlo simulation and get recoverable resources in the area.Cognition and conclusion:The geological and sedimentary characteristics of sandstone reservoirs hosted by oil sands are the basis for identifying sweet spots and non-sweet spots.Regional geological study of evaluation area,detailed geological and engineering evaluation of developed areas have a great impact on developable segment identification of oil sands reservoir and the rationality of resources evaluation.On basis of above solid work,it provides a solid foundation,objective parameter selection and reasonable result probability method for evaluating recoverable bitumen in a oil sand project.Innovation:Based on the geological study,combined with the data analysis of developed area,the sweet spots and non-sweet spots are depicted,and recoverable resources of oil sand are calculated by a probability method.
