A technical basis for carbon dioxide storage

Cal Cooper on behalf of the CO₂

This paper is the synopsis of a larger work completed under the auspices of the CO₂ Capture Project, an international effort funded by eight of the world’s leading energy companies. It seeks to explain the rationale for the geological storage of carbon dioxide (CO₂) based on insights from the practical experience of the oil and gas industry. It considers the key technical applications that will make storage possible, and the subsurface management processes that will provide confidence to all stakeholders that storage is effective. Four broad areas are described including, the selection and characterization of sites for CO₂ storage; issues of well integrity and well construction; the requirements of monitoring programs for appropriate data collection and risk management. Finally, issues arising from storage operations and the eventual closure and decommissioning of CO₂ storage sites are addressed.

CO₂ Capture Project Phase 2 (CCP2) – Storage Program: Closing Long-Term CO₂ Geological Storage Gaps Relevant to Regulatory and Policy Development

Scott Imbus, Dan Kieke, Walter Crow, Marcos Briceno, Scott Rennie, Calvin Cooper, Alessandra Simone

The CCP2 (2005 -2008) is a consortium is engaged in reducing CO₂ capture costs and improving confidence in CO₂ storage. The consortium has co-funding from EU, Norway and the US DOE. The CCP2 Storage program project portfolio focuses on technical assurance issues of importance to regulators, policymakers and other stakeholders. These include simplified and transparent protocols for assessing the storage project lifecycle, long term well materials stability under CO₂-rich conditions, geochemical and geomechanic al interactions impacting the containment system stability and feasibility of novel remote sensing and geophysical techniques for monitoring CO₂ storage. Work has begun on the CCP3 Storage (2009+) program which will continue to address remaining, substantial CO₂ storage issues.

Characterizing fault-plume intersection probability for geologic carbon sequestration risk assessment

Preston D. Jordan, Curtis M. Oldenburg, and Jean-Philippe Nicot

Leakage of CO₂ out of the designated storage region via faults is a widely recognized concern for geologic carbon sequestration. The probability of such leakage can be separated into the probability of a plume encountering a fault and the probability of flow along such a fault. In the absence of deterministic fault location information, the first probability can be calculated from regional fault population statistics and modelling of the plume shape and size. In this study, fault statistical parameters were measured or estimated for WESTCARB’s Phase III pilot test injection in the San Joaquin Valley, California. Combining CO₂ plume model predictions with estimated fault characteristics resulted in a 3% probability that the CO₂ plume will encounter a fault fully offsetting the 180 m (590 ft) thick seal.The probability of leakage is lower, likely much lower, as faults with this offset are probably low-permeability features in this area.

Reactive Transport of CO₂ in Saline Aquifers with implicit geomechanical analysis

Bjørn Kvamme, Shunping Liu

Geological storage of CO₂ in saline aquifers is a promising way to reduce the concentration of the greenhouse gas in the atmosphere. Injection of CO₂ will, however, lead to dissolution of minerals in regions of lowered pH and precipitation of minerals from transported ions in regions of higher pH. The geomechanical implications of these changes on the stability of the reservoir are of crucial importance in the evaluation of potential injection reservoirs. The possible injection rate for given over-pressures of the injected CO₂ depends on the porosity and permeability of the rock matrix in the vicinity of the injection well. Local fracturing in this region can be a tool for increasing the injection flow rate but a geomechanical analysis will be needed in order to make sure that this fracturing will not affect the geomechanical stability outside this limited region to a significant degree. This paper presents a new rewritten version of RetrasoCodeBright (RCB) for simulations of CO₂ storage in saline aquifers. An advantage of this code compared to other codes is the implicit geo-mechanical module. The code has been rewritten to account for non-ideal gas through corrections of gas density and gas solubility in all transport terms. Newton-Raphson method used to solve the flow and mechanics in RCB has been improved so as to improve convergence even under high gas injecting pressures. A 2D hydro-chemical-mechanical problem is used to illustrate the modified RCB code. This particular test case is chosen as a block of pure calcite embedded in top or bottom sections with mineralogy similar to that of the Utsira formation. The test case is designed so as to investigate horizontal migration and injection is controlled by a pressure difference between injection on the right hand side (140 bar) and a constant pressure (100 bar) on the left hand side of the system. For this particular test case the Soave Redlich Kwong (SRK) equation of state has been applied for compressibility factors and fugacity coefficients but can easily be replaced with more accurate equations of state for CO₂. The simulated results show as expected a significant buffering effect which slows down the mineral erosion close to the injection zone and for the specific example the only region which appear to have potential geomechanical implications of the injected CO₂ is close to the left side of the block where the difference between stress and overpressure indicate region of instability after 100 years of injection.
