Caprock Core Recovery & Management
Diligent caprock core handling and management is crucial to ensure quality results that accurately reflect caprock properties in the reservoir.
Reliable data begins with capturing the caprock core in a manner that preserves original rock properties. Caprock core is different from oil sands core due to its high sensitivity to aggressive handling. Additionally, the core cannot freeze during winter transportation and can dry out in conventional storage which will change its physical properties completely. Therefore, caprock core must be handled by specialized core handlers. After the successful retrieval, the core is subsequently transferred to Calgary, photographed, geologically logged and stored for use in mechanical testing programs. The core needs to be processed so that geologists can interpret the stratigraphy. Faulting and jointing needs to be determined and engineering must select samples for physical property testing.
