Caprock Integrity

By: Bitcan  09-12-2011

Caprock integrity is a complex subject involving several factors including in-situ geology, operation and well hardware. Due to its integrated nature, BitCan offers a turn-key solution to your caprock integrity concerns under a single roof and without subcontracting:

  • Our custom-designed triaxial laboratory test system measures the as well as . Our laboratory system can simulate the various operating impacts such as shale hydration during drilling, conductive heating behind the casing, and steam leak. All tests are carried out under stress and deformation conditions similar actual field situations.

"Petroleum production is valuable. But we have a more valuable resource, i.e. the groundwater aquifer, to protect." Whether you are required by ERCB to answer their concerns on the caprock integrity, or you have experienced real problems in your operations, BitCan is the optimal resource for you. In our opinion, SAGD is not necessarily safer than CSS, but with proper caution and exercise, we can manage the caprock integrity very well.

Caprock integrity is equally important for other subsurface stimulation, injection or production activities such as subsurface CO2 sequestration. They all share the same mechanical principles and working approaches although the particular geological context may be different. BitCan's integrated service capabilities are unique in this area. We characterize the in-situ geology by mechanical strengths, existence of faults, their orientations and mechanical properties. We also measure the original in-situ stresses and simulate the induced stresses and deformation during the CO2 sequestration.

Our petroleum geomechanics software suite consists of individual modules for near-wellbore geomechanics (borehole stability and sand management) and reservoir geomechanics involving caprock and casing integrity, reservoir compaction and dilation, coupled geomechanical reservoir processes and innovative reservoir processes.


Reservoir Dilation

Out of its innovation spirit, BitCan has for long been championing proactive utilization of geomechanics in the in-situ development of the oilsands reservoirs. Unique well completion and stimulation measures in the thermal recovery enable more proactive control on the rock deformation and failure processes. We are also investigating proactive field measures to break down shale stringers in the oilsands payzone during the SAGD operations.



Analysis and design on overburden integrity, sealing capacity of the overburden for reservoir stimulation, hydrocarbon storage, subsurface waste disposal, CO2 sequestration, and etc. Geomechanical characterization and coupled geomechanical reservoir simulation for naturally fractured reservoirs. Innovations in in-situ development of unconventional reservoirs such as heavy oil and oil sands.


Compressive strength

With integrated field, laboratory and simulation capabilities, BitCan is the one-stop source for your needs in studying the compressive strength. Operators are required by ERCB to provide data on the compressive strength of their caprock shales to address the integrity concerns. Our on-site shale preservation and transport system ensures high-quality cores used for the laboratory tests.
