In Salah CO2 injection modelling: a preliminary approach to predict short term reservoir behaviour
In Salah CO2 injection modelling: a preliminary approach to predict short term reservoir behaviour

1st September 2010

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

This paper presents an approach developed by IFP Energies nouvelles in the scope of the CO2ReMoVe project to study short term CO2 migration into the Krechba reservoir of the In Salah geologic carbon sequestration (GCS) project in Algeria. The authors provide an overview of CO2 storage at In Salah, followed by the short term performance assessment approach for 3D flow modelling.  A description of 3D geomechanical and fluid flow modelling is followed by the authors’ conclusions.

In Salah CO2 Storage JIP: site selection, management, field development plan and monitoring overview
In Salah CO2 Storage JIP: site selection, management, field development plan and monitoring overview

1st September 2010

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

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.

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.

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.

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.

The In Salah Gas CO2 Storage Project
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.
