Vendor Agnostic
C44 GuardianTM embraces a vendor-agnostic approach to leverage the benefits of flexibility, integration, scalability, and agility. Our API framework provides the interoperability to facilitate seamless data exchange to-and-fro customer’s IT ecosystem.
Flexible and Customizable
There are no one-size-fits-all solutions when it comes to carbon storage. The monitoring approach must be customized to the risks and uncertainties of specific storage sites. C44 GuardianTM offers the flexibility and scalability to support the customer needs.
Cost Effective
C44 GuardianTM offers a cost-efficient and flexible business model for different phases of the project. With minimal third-party software licensing cost and efficient cloud data architecture, we can deliver the cost benefits to improve the project viability.
RESERVOIR
CO2 is injected for storage into depleted oil and gas reservoirs or into saline aquifers. Understanding structure and physical properties of the reservoir formations is essential for planning, monitoring and securely storing CO2.
C44 GuardianTM combines the visualization of reservoir structure and properties with monitoring results such as plume position or the occurrence of induced seismic events. It is focused on the essential information required for monitoring and securely storing CO2 in the underground.
PLUME
The injected CO2 forms a plume in the reservoir formation originating from the injection well. Monitoring the plume position, shape and evolution over time are essential for judging the containment of the injected fluid and the conformity with predictions.
C44 GuardianTM combines pre-injection modeling and simulation results with interpreted monitoring data from a variety of geophysical methods such as 3D seismic, VSP, and gravimetric surveys. Its functionality is tailored to the monitoring of the CO2 plume in the reservoir over extended time periods.
TOP SEAL
Integrity of the top seal of the reservoir is essential to avoid leakage of CO2 into the overburden and eventually to shallow formations and the surface.
C44 GuardianTM integrates structural information, especially position and geometry of faults, with the stress and pore pressure information and with the data from monitoring systems such as well and surface based seismic monitoring. It also provides the operator with the tools to maintain injection pressures at a safe limit below the fracture pressure of the top seal formation.
SURFACE
Geophysical methods and geochemical sampling in shallow formations, in the ground water, or at the surface can provide indication for eventual leakage of CO2 from the storage formation and migration towards the surface. C44 GuardianTM aggregates near-surface and surface data, combines the data with pre-injection data as well as data from deeper measurements in a comprehensive overview to the CCS storage operator. It provides all the digital tools to ensure containment of the injected CO2 at all times.
WELLS
Wells can be locations for sampling of physical parameters, but they can also be pathways for leakage of CO2 from the reservoir layer if well integrity is compromised. C44 GuardianTM handles data measured at discrete depths in the well, data measured by fiberoptical cables in a continuous manner along the well trajectory or data gathered at the wellhead. Interpreting and analyzing these measurements it provides information about the reservoir and the position of CO2 in it. But importantly it also allows to continuously monitor the integrity of the well and eventual leakage of CO2 along the well.
SEISMICITY
Injection of CO2 in underground rock formations may trigger seismic events on pre-existing faults in the reservoir formation or in other formations that are reached by the pressure changes caused by the injection. Stress and pore pressure state, as well as the existence, position and orientation of faults has to be understood as much as possible to define an injection strategy that minimizes the risk for inducing micro-seismic events.
Before injection commences the naturally occurring seismicity in the area should be determined as a baseline against which future seismicity can be compared.
C44 GuardianTM provides all the tools to monitor the occurrence of seismic events 24/7 from surface networks, downhole instruments or fiberoptics. It automatically detects and localizes seismic events and displays all the information to the operator.
