A017 SIMULATION STUDY OF CO2 RETENTION DURING TERTIARY EOR FLOOD IN IVANIĆ OILFIELD D. DOMITROVIĆ 1 S. ŠUNJERGA 1 B. GORIČNIK 2 D. VULIN 2 1 1 INA-Naftaplin Šubićeva 29 Zagreb Croatia 2 University of Zagreb – Faculty of Mining Geology and Petroleum Engineering Pierottijeva 6 Zagreb Croatia The outset of industrial age has been accompanied with a steady increase of atmospheric concentration of carbon dioxide (CO2) from anthropogenic sources mainly from fossil fuel combustion within energy sector as well as from other industrial activities. Ever since the adverse effect of the process on climate change (i.e. global warming) has

A019 Abstract The mechanical impact of CO2 injection 1 B. ORLIC B. SCHROOT Netherlands Institute of Applied Geoscience TNO – National Geological Survey PO Box 80015 3508 TA Utrecht The Netherlands. The mechanical impact of CO2 injection into a depleted hydrocarbon field or aquifer is caused by changes in the stress field resulting from changes in the pore pressure and volume of the rock. Mechanical processes can lead to the loss of reservoir and caprock integrity and the reactivation of existing faults. A geomechanical numerical modelling approach to determining the mechanical impact of CO2 injection is presented and demonstrated on

A025 1 INTRODUCTION SPARSE RADON TRANSFORMS WITH BOUND-CONSTRAINED OPTIMIZATION ANTOINE GUITTON Department of Geophysics Stanford University Stanford CA 94305 USA Radon transforms are popular operators for velocity analysis (Taner and Koehler 1969; Guitton and Symes 2003) noise attenuation (Foster and Mosher 1992) and data interpolation (Hindriks and Duijndam 1998; Trad et al. 2002). One property that is often sought in radon domains is sparseness where the energy in the model space is focused without transformation artifacts. Sparseness is especially useful for multiple attenuation and interpolation. In practice depending on the radon transform sparseness can be achieved either in the Fourier

A029 Fast 3D wave-equation prediction of multiples 1 Summary. We present a new efficient wave-equation scheme for prediction and subtraction of water-layer multiples and peg-legs from locally 1D sea-floor with an arbitrary 3D structure below it. The method is suitable for the majority of data from the North Sea. For current quasi-3D marine acquisition with poor sampling between shots in the crossline direction the method is accurate for receiver-side prediction but approximate for source-side prediction. The prediction and adaptive subtraction of multiples are performed in the same domain therefore no additional sorting or additional transformations are required. All source-side and
