Characterisation of the Krechba CO2 storage site: critical elements controlling injection performance
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This paper explores the reservoir features that have proven critical in controlling injection performance at the In Salah geologic carbon sequestration (GCS) project in Algeria. The paper is divided into the three main themes of characterisation: structural geology, fracturing, and pore space characterisation. The authors conclude that structural geological and rock mechanical aspects are most critical in the early injection phase. When considering medium to long term effects, characterisation of the pore space, combined with the dynamically created fracture permeability, becomes more important.

Characterizing and predicting short term performance for the In Salah Krechba Field CCS Joint Industry Project
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This paper describes models and simulations that look ahead up to 10 years into the performance of CO2 injection at the In Salah geologic carbon sequestration (GCS) project in Algeria. The authors describe the field geology, static earth model, dynamic situation model, and the history match process and results of predictive dynamic simulation. The simulation suggests that injected CO2 will reach some gas production wells by year 2015.

Coupled non-isothermal, multiphase fluid flow, and geomechanical modeling of ground surface deformations and potential for induced micro-seismicity at the In Salah CO2 storage operation
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This paper presents the results of a modelling study to assess the effectiveness of long reach horizontal injection wells at the In Salah geologic carbon sequestration (GCS) project in Algeria. The authors investigate monitoring techniques to evaluate the performance of a CO2-injection operation in relatively low permeability formations. And, they analyse simulation results in terms of injection-induced reservoir stress and the potential for injection-induced micro-earthquakes at Krechba.

In Salah CO2 Storage JIP: site selection, management, field development plan and monitoring overview
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This paper presents information on the Joint Industry Project (JIP) established to monitor CO2 storage at the In Salah geologic carbon sequestration (GCS) project in Algeria. Site selection was guided by the standard oil-industry Capital Value Process (CVP). After four years of injection and monitoring, a Quantified Risk Assessment (QRA) was performed to update the development plan. Monitoring included satellite facilitated measurements of surface deformation, as well as conventional oilfield technologies.

In Salah CO2 storage JIP: carbon dioxide plume extension around KB-502 well. New insights into reservoir behaviour at the In Salah storage site
1st September 2010
Topic(s): CO2 storage, Engineering and project delivery
This paper presents information by the Joint Industry Project established to monitor CO2 storage at the In Salah geologic carbon sequestration (GCS) project in Algeria. Satellite-based interferometry (InSAR) technology detected surface uplift over all three horizontal CO2 injection wells shortly after the start of CO2 injection. Imperial College London carried out simulations of CO2 injection aiming to gain a better understanding of the reservoir behaviour. The findings are reported in this paper.

In Salah CO2 Storage JIP: hydromechanical simulations of surface uplift due to CO2 injection at In Salah
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This paper presents information by the Joint Industry Project established to monitor CO2 storage at the In Salah geologic carbon sequestration (GCS) project in Algeria. This study describes detailed simulations of the hydromechanical response in the vicinity of the KB-502 CO2 injector in an attempt to explain why the morphology of the observed surface deformation differed from that above the other injectors at the field.

In Salah Gas CO2 Storage JIP: surface gas and biological monitoring
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This paper presents information by the Joint Industry Project established to monitor CO2 storage at the In Salah geologic carbon sequestration (GCS) project in Algeria. The authors describe the methods for measurements and surveys, and explain the results for the 2009 monitoring program. Concluding remarks note that in spite of the environmental factors and scarcity of vegetation, plant diversity is relatively high, and that soil gas data did not indicate any CO2 leakage except possibly at KB-5.

Pore-scale modelling of CO2-brine flow properties at In Salah, Algeria
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This paper describes an integrated pore-scale modelling approach to reconstruct three reservoir rock samples from Krechba field at the In Salah geologic carbon sequestration (GCS) project in Algeria. Pore scale modelling is an important new tool that includes rock modelling, calculation of petrophysical properties, 2-phase fluid flow simulations and comparison of predicted results with laboratory data. This method of fast and reliable characterisation plays a critical role in CO2 storage modelling by shifting the saturation range for which the CO2 plume is mobile.

Simulation of CO2 distribution at the In Salah Storage Site using high-resolution field-scale models
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This report describes the use of an invasion percolation modelling approach to simulate the CO2 migration process at the Krechba field of the In Salah Storage Site in Algeria. The field-scale model involves 56 million cells with dimensions of 10x10x2 meters. This high-resolution model captures the reservoir heterogeneity with respect to both the fault and fracture distributions. The simulation results are reasonably consistent with the inferred CO2 distribution after 5 years of injection, and indicate that the current distribution of CO2 is principally related to the fracture network. Initial results for predictive simulations of the post-injection period are sensitive to, and principally constrained by, the fault distribution and the multiphase flow behaviour. The simulation results highlight the role that high-resolution heterogeneous field-scale models can play in developing a comprehensive storage monitoring program.

Wellbore integrity at the Krechba Carbon Storage Site, In Salah, Algeria: 2. Reactive transport modeling of geochemical interactions near the cement – formation interface
1st September 2010
Topic(s): Carbon capture use and storage (CCUS), CO2 storage, Engineering and project delivery
This paper describes a reactive transport modeling approach to assess key geochemical reactions between wellbore cement, formation mineralogy, and injected supercritical CO2 at the Krechba natural gas field at In Salah, Algeria. The findings informed a reactive transport model which considered advective transport of CO2 along the wellbore-formation interface and diffusive transport of CO2 and brine constituents into juxtaposed wellbore cement.
