Pre-existing faults constitute a potential risk to storage security owing to the elevated pore pressures likely to result from large-scale fluid injection. Determination of the regional\n            <jats:italic>in situ<\/jats:italic>\n            stresses permits mapping of the stress tensor affecting these faults. Either normal or strike-slip faulting conditions are suggested to be prevalent, with the maximum horizontal stress orientated 33\u00b0\u2013213\u00b0. Slip-tendency analysis indicates that some fault segments are close to being critically stressed under strike-slip stress conditions, with small pore-pressure perturbations of approximately 1.5\u2005MPa potentially causing reactivation of those faults. Greater pore-pressure increases of approximately 5\u2005MPa would be required to reactivate optimally orientated faults under normal faulting or transitional normal\/strike-slip faulting conditions at average reservoir depths. The results provide a useful indication of the fault geometries most susceptible to reactivation under current stress conditions. To account for uncertainty in principal stress magnitudes, high differential stresses have been assumed, providing conservative fault-stability estimates. Detailed geological models and data pertaining to pore pressure, rock mechanics and stress will be required to more accurately investigate fault stability.\n          <\/jats:p>","DOI":"10.1144\/petgeo2016-036","type":"journal-article","created":{"date-parts":[[2016,7,14]],"date-time":"2016-07-14T04:43:17Z","timestamp":1468471397000},"page":"211-222","source":"Crossref","is-referenced-by-count":27,"title":["Carbon dioxide storage in the Captain Sandstone aquifer: determination of\n            <i>in situ<\/i>\n            stresses and fault-stability analysis"],"prefix":"10.1144","volume":"22","author":[{"given":"John D.
