Quantitative integration of flow simulation and 4-D multicomponent seismic in a CO 2 WAG EOR project. A 4D seismic monitoring survey is planned to delineate gas and water fronts in reservoir flow units about 10m thick, providing critical information to help piloting a planned 6-month WAG cycle for improved recovery. In addition to suggesting that the occurrence of elliptical whirling motion more than 1 week before the eruption, our analysis of seismic time-lags also implies that the 2009 eruption was accompanied by qualitative changes in the magma wagging behavior including fluctuations in eccentricity and a reversal in the direction of elliptical whirling motion when the eruption was immediately impending. Time lapse seismic is now well established as a reliable reservoir monitoring technique that certainly adds value to the reservoir management of a hydrocarbon. Seismic and Electrical Resistivity Tomography 3D Monitoring at the Ketzin Pilot Storage Site in Germany. We test our model by analyzing pre-eruptive seismic data from the 2009 eruption of Redoubt Volcano. We also calculate the seismic P-wave response of the crustal material around the volcanic conduit to the new whirling motions and propose seismic diagnostics for different wagging patterns using the time-lag between seismic stations. As a potential carbon sequestration mechanism, CO 2 WAG projects will be subject to some degree of monitoring and verification, either as a regulatory. In the presence of viscous effect we identify new 'coiling' and 'uncoiling' column bending shapes with relatively higher and comparable rates of dissipation to the original two-dimensional magma wagging model. We present the current status of time-lapse seismic integration at the Farnsworth (FWU) CO 2 WAG (water-alternating-gas) EOR (Enhanced Oil Recovery) project at Ochiltree County, northwest Texas. In the absence of viscous damping, the magma column undergoes 'whirling' motion: the center of each horizontal section of the column traces an elliptical trajectory. While prior studies were restricted to two-dimensional lateral oscillations, here we explore three-dimensional motion and additional modes of oscillations. gas to water and water to gas) where there are significant pressure, flow and temperature transients leading to possibility of various flow assurance related. Of particular interest is the the period of change over interval (i.e. Here we revisit and extend to three dimensions the magma-wagging model for tremor (Jellinek and Bercovici, 2011 Bercovici et al., 2013), wherein a stiff magma column rising in a vertical conduit oscillates against a surrounding foamy annulus of bubbly magma, giving rise to tremor. This paper presents the results of the modelling and simulations of WAG operation carried out on a horizontal well. The ubiquitous characteristics of this tremor imply that its causes are potentially common to silicic volcanoes. Seismic tremor characterized by 0.5-7 Hz ground oscillations commonly occur before and during eruptions at silicic volcanoes with widely ranging vent geometries and edifice structures.
