The economic and environmental impact of an integrated CO2-EOR project in the Buzzard field in the North Sea is investigated through a life cycle analysis, a standard economic analysis and a more advanced geo-economic simulation. Results show the benefits of combining EOR with CO2 storage. However, the current economic environment provides insufficient long-term outlooks to justify the investment.

Since the world average temperature is on the rise, severe measurements should be considered due to decrease the concentration of greenhouse gases which are the main reason of global warming. Geological sequestration of the CO2 speculated as one of the most efficient method for mitigate the problem. As the injected CO2 stream is not always a pure one, a more accurate assessment of the impurities effects on various part of the sequestration process would be desired. As equations of state are not able to completely support the thermodynamic attributes of impure CO2 injected stream, developed computational modeling would be more appropriate. In this study, due to obtain a way of predicting vapor liquid equilibrium of CO2 binary mixtures, not fully depending on the experimental data, a novel and accurate computational method is presented. This alternative, uses Adaptive Neuro-Fuzzy Interference System (ANFIS) together with Genetic Algorithm as an optimization tool. As a result, the developed model shows a great i

A CCS monitoring plan should demonstrate containment of CO2, ensure that CO2 distribution in the storage complex is monitored and understood to ensure long term conformance and assess the effectiveness of any corrective measures taken in case of a leakage out of the storage complex. Such a monitoring programme should be flexible and designed to address all aspects described above in a cost efficient and flexible manner. Here we discuss some aspects of monitoring the proposed Smeaheia site offshore Norway.

Equinor with Shell and Total, evaluate the feasibility for full-scale CO2 capture and storage project in Norwegian continental shelf. One of the challenges for CO2 storage sites is to assure containment and to assess possible leakage paths to the surface. Understanding the overburden’s geological setting is crucial for this assessment. As part of the overburden risk assessment, we investigate the potential for quantifying porosity from seismic inversion data. Knowledge of the porosity distributions, may enable us to employ porosity-permeability models in the future to assess leakage pathways into the overburden.

Summary In the context of carbon capture and storage (CCS), quantitative estimation of injected CO2 is of vital importance to verify if the process occurs without any leakage. From a geophysical perspective this is challenging as a CO2 plume has a severe imprint on seismic data. While this makes delineation of the plume rather straightforward, for quantitative interpretation a technique is required that takes complex wave propagation, including multiple scattering and mode conversions into account. In this abstract a wave-equation based AVO technique is discussed and successfully demonstrated on a seismic dataset from the Sleipner site. The technique solves the exact wave-equation which means that tuning effects are properly modelled. The scheme directly inverts for compressibility and shear compliance as these parameters are more closely related to saturation than conventional impedances. From this the total amount of injected CO2 is calculated and found to be in good agreement with the known value at the time when the data was acquired.
