Using 3D Printed Reservoir Rock Analogs to Validate Numerical Models

Canada’s natural resource industries access energy sources such as oil sands, coal, bitumen carbonates and shales through in situ processes (e.g. horizontal drilling). During these operations, changes in pressure and temperature affect the earth structures (caprock) that seal and contain the energy sources, which could compromise the safety of the operation and surrounding environment. For example, in 2010, the caprock seal of an operating steam-assisted gravity drainage (SAGD) project on a shallow oil sands reservoir was dramatically ruptured, resulting in a large explosion and the creation of a 75 m x 125 m surface crater in the area. In 2014, another steam extraction-based operation had a breach in the caprock seal, resulting in bitumen seepage to the surface.
