Simulation of CO2 distribution at the In Salah Storage Site using high-resolution field-scale models
Simulation of CO2 distribution at the In Salah Storage Site using high-resolution field-scale models

1st September 2010

Topic(s): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

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
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): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

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.

CO2 sequestration monitoring and verification technologies applied at Krechba, Algeria
CO2 sequestration monitoring and verification technologies applied at Krechba, Algeria

1st February 2010

Topic(s): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

This paper provides an overview of the In Salah CO2 storage project. The experimental and demonstration project commenced in 2004. In 2005 a joint industry project was set up to monitor the CO2 storage process using a variety of geochemical, geophysical, and production techniques over an initial five-year period. The authors describe risks and corresponding monitoring technologies including the use of satellite imaging.

Evaluating the impact of fractures on the long-term performance of the In Salah CO2 storage site
Evaluating the impact of fractures on the long-term performance of the In Salah CO2 storage site

1st January 2008

Topic(s): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

This paper presents the authors’ current knowledge on the characterisation of faults and fractures at the CO2 storage demonstration site at the Krechba natural gas field at In Salah, Algeria. The authors discuss their current understanding of fault and fracture properties at Krechba, which is essential for realistic predictions of CO2 flow behaviour at the site. Furthermore, an extensive monitoring program is underway to improve the characterisation of the Krechba field as storage location and to verify the applicability of a number of monitoring methods for CO2 storage purposes.

Satellite imaging to monitor CO2 movement at Krechba, Algeria
Satellite imaging to monitor CO2 movement at Krechba, Algeria

1st January 2008

Topic(s): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

This paper describes current and future use of satellite data to monitor and model injection sites at the Krechba natural gas field at In Salah, Algeria. The authors explain the current monitoring programme at Krechba, and the role satellite imagery plays. The authors conclude that experience at In Salah shows that satellite imagery now has the resolution to be a key monitoring technology for onshore storage.

Detection of surface deformation related with CO2 injection by DInSAR at In Salah, Algeria
Detection of surface deformation related with CO2 injection by DInSAR at In Salah, Algeria

1st January 2008

Topic(s): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

This paper describes the use of interferometric synthetic aperture radar to map changes in the surface of the Krechba natural gas field at In Salah, Algeria. The authors state this this is the first instance the spaceborne system has been used for this purpose. They describe methodology and results, concluding that this system is a promising, cost-effective monitoring tool compared with other conventional geophysical surveys.

Coupled reservoir-geomechanical analysis of CO2 injection at In Salah, Algeria
Coupled reservoir-geomechanical analysis of CO2 injection at In Salah, Algeria

1st January 2008

Topic(s): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

This paper describes coupled reservoir-geomechanical modeling of CO2 injection at Krechba, at the In Salah geologic carbon sequestration (GCS) project in Algeria. Several studies have investigated surface uplift surrounding Krechba injection sites. In this approach, the authors simulate the actual CO2 injection in a three-dimensional model around one horizontal injection well, and conduct sensitivity studies to determine the cause and mechanisms of the uplift.

The In Salah Gas CO2 Storage Project

1st December 2007

Topic(s): Engineering and project delivery, Carbon capture, use and storage (CCUS), CO2 storage

This paper provides an overview of the In Salah Gas CO2 Storage Project, based in the Ahnet-Timimoun Basin in the Algerian Central Sahara. The project was established as a public demonstration of storage assurance, to capture and reinject waste CO2 from natural gas production, that would have otherwise been vented to the atmosphere. This is a Joint Industry Project (JIP) with participation from industry, academia, government and non-government organisations.
