Until recently, the seismic method was the dominant technique used for reservoir monitoring. However, the cost of seismic surveys makes this method prohibitive in monitoring sequestration projects where there is not a direct profit. Moreover, some environments present challenges for seismic acquisition as in urban areas. In this paper we present a feasibility study of permanent gravity gradiometry monitoring of CO2 sequestration in a deep reservoir using a novel approach involving both borehole and surface measurements. The interpretation is based on joint iterative migration imaging of the surface and borehole data. The advantage of this method is that the surface data provide a good estimate of the horizontal extent of the injection zone, while the borehole data control the depth of the target, which increases the sensitivity and resolution of the method. We illustrate the effectiveness of the gravity gradiometry method by computer simulating CO2 injection monitoring in the Kevin Dome sequestration site in Montana, USA.Presentation Date: Tuesday, October 16, 2018Start Time: 1:50:00 PMLocation: 213B (Anaheim Convention Center)Presentation Type: OralKeywords: monitoring, gravity tensor, migration, multicomponent, imagingPermalink: https://doi.org/10.1190/segam2018-2996382.1FiguresReferencesRelatedDetailsCited byReferences16 November 2022 SEG Technical Program Expanded Abstracts 2018ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2018 Pages: 5520 publication data© 2018 Published in electronic format with permission by the Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 27 Aug 2018 CITATION INFORMATION Le Wan, Muran Han, Hassan Ali AlJanobi, and Michael S.
