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.

Applications

Caprock core management is key to any successful Triaxial lab tests. Proper management procedures maintain original core properties and prevent any fractures from being created during transportation and storage.
Capturing caprock for Triaxial Analysis early in a delineation program can reduce time needed to respond to Supplementary Information Requests (SIR’s) from the Alberta Energy Regulator (AER), thereby reducing thermal application approval time.

Features & Benefits

BGES is the proud provider of end-to-end caprock solutions. Core is collected at the wellsite and all of the handling and analysis can be coordinated through a single source supplier.
A final integrated report will be ready for insertion directly into a Thermal Application or submission to the AER.

Operations

BGES is equipped to provide a mobile facility at the wellsite. Specialized handlers will be on location to assist with recommended drilling parameters. Careful cutting, transportation and preservation of caprock starts at the rig floor. Our experienced staff is trained for these delicate tasks.
Using our specially designed environmentally-controlled trailer, the caprock core is transported to a dedicated lab in Calgary for processing. BGES also has the equipment to complete the physical testing at low and high temperatures.
