Resolving Disagreements in Porosity and Permeability Values in Core Analysis Data for the Montney Formation

据估计，加拿大的非常规资源可能含有多达1100万亿立方英尺 页岩气和32万亿桶非常规石油。然而，包含这些资源的水库 提出了许多挑战。许多研究这些储层的实验室技术提供了不一致的结果。 结果例如，孔隙度值，衡量岩石中存在多少空间来容纳石油 流体可能具有100%的不确定性，而渗透率（衡量流体流动容易程度的指标）可能 都有超过一个数量级的不确定性。GLJ石油咨询公司一直在经历这些 Montney地层的孔隙度和渗透率数据存在问题，需要一种方法来验证 哪个数据是正确的。他们将提供访问一个大型数据库的核心分析结果，而申请人 一名博士生将利用这些数据来确定这些不确定性的来源， 测量协议，以帮助减少这些不确定性。这将大大提高水库的质量 GLJ提供的评估使他们能够更有信心地推销他们的服务。如果成功，这 这项工作可以大大促进非常规石油资源的开发， 价值数万亿美元

It has been estimated that unconventional resources in Canada could contain as much as 1100 trillion cubic feet of shale gas and 32 trillion barrels of unconventional oil. However, the reservoirs that contain these resources offer many challenges. Many of the laboratory techniques to investigate these reservoirs provide inconsistent results. For example, porosity values, a measure of how much space exists in the rock to hold the petroleum fluids can have uncertainties of 100% while permeability, a measure of how easily the fluids will flow, can have uncertainties of over an order of magnitude. GLJ Petroleum Consultants has been experiencing these problems with both porosity and permeability data for the Montney formation and requires a method to verify which data is correct. They will provide access to a large data base of core analysis results while the applicant and a doctoral student will work with this data to determine the sources of these uncertainties and develop a measurement protocol to help reduce these uncertainties. This will greatly enhance the quality of the reservoir evaluations produced by GLJ allowing them to market their services with greater confidence. If successful, this work could significantly advance the development of unconventional petroleum resources, resources that could be worth trillions of dollars.
