A full field simulation of the In Salah gas production and CO2 storage project using a coupled geo-mechanical and thermal fluid flow simulator
1st September 2010
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.
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.
This paper presents the results of an analysis of three risk assessment methods using the In Salah geologic carbon sequestration (GCS) project in Algeria as a backdrop. The methods assessed are the RISQUE QRA (Quantitative Risk Assessment) process, a Certification Framework developed for the CO2 Capture Project (CCP), and the Quantitative Risk Through Time Analysis (QRTT). The authors conclude that overall both CF and RISQUE QRA methodologies were consistent and provided useful insights into the In Salah project.
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.
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.
