SALT AND CAPROCK CORE RECOVERY & MANAGEMENT
Diligent core handling and management is crucial to ensure quality results that accurately reflect rock properties in its in-situ condition.
Reliable data begins with capturing the caprock core in a manner that preserves original rock properties. Salt and caprock cores are very delicate and must be handled differently than conventional cores. Caution must be exercised to prevent aggressive drilling/coring operations, excessing handling, freezing, and moisture loss.
BGES is equipped to provide a mobile facility at the wellsite. A Professional Geologist or Geotechnical Engineering will be on location to oversee the coring process. Careful cutting and preservation of core is performed by our specially-trained core technicians on the rig floor.
Damage to cores during transportation is very common, potentially making them inadequate for geotechnical lab testing. As a result, caprock core must be handled by specialized core handlers. After the successful retrieval, the core is transported using our environmentally-controlled transport unit to BGES’ dedicated lab in Calgary for processing and storage.
At the Lab
Upon arrival at our Calgary geotechnical laboratory, cores are CT scanned with optional depth correlation, inspected, photographed, geologically logged, and carefully stored in an environmentally-controlled room when not in use. Our geotechnical experts will work with clients to select samples for physical property testing.
Geomechanical modelling is important for a subsurface cavern at different stages of its lifecycle. Reliable geomechanical models are highly dependent on input data from geotechnical lab tests, and diligent core management is key to any successful geotehnical lab tests.
Features & Benefits
BGES is a provider of end-to-end geotechnical lab testing solutions for salt caverns. From core collection at the wellsite to lab testing and numerical modelling, can be coordinated through a single-source supplier. A final integrated report prepared by a technical professional will be ready for regulatory submission.
At the wellsite, BGES will provide a mobile facility and specialized handlers to assist with recommended drilling parameters and to process the collected cores. Using specially-designed environmentally-controlled unit, cores are transported to our geotechnical lab in Calgary for processing and storage.
