In Salah CO2 storage JIP: carbon dioxide plume extension around KB-502 well. New insights into reservoir behaviour at the In Salah storage site
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 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
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
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
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.

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

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

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.

Characterisation of the Krechba CO2 storage site: critical elements controlling injection performance
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.
