Leakage risk assessment of the In Salah CO2 storage project: applying the certification framework in a dynamic context
Leakage risk assessment of the In Salah CO2 storage project: applying the certification framework in a dynamic context

1st January 2011

Organisation(s): Lawrence Berkeley National Laboratory (LBNL), University of Texas

Topic(s): Carbon capture, CO2 storage, Use and storage (CCUS)

The In Salah Gas project at Krechba, in the Sahara Desert of Algeria, is the world’s largest on-shore saline-formation geologic carbon sequestration (GCS) project. This paper describes a simple risk assessment approach for evaluating CO2 and brine leakage risk at the site. In this report the authors describe an application of the certification framework (CF) risk assessment approach over two different stages. Results show that the assessment of likelihood of various leakage scenarios increased as more information became available, while assessment of impact stayed the same. Ongoing mitigation, modelling, and monitoring of the injection process is recommended.

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

This paper reports on the results of a full field simulation model of CO2 production and injection at the In Salah geologic carbon sequestration (GCS) project in Algeria. The study followed CO2 from the injection wellheads, down the wells and through the completions and into the storage interval. The resulting models describe likely future behaviours of the storage system.

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
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

Organisation(s): Lawrence Berkeley National Laboratory (LBNL)

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

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.

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

Organisation(s): Lawrence Berkeley National Laboratory (LBNL)

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

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.
