We show that it may be possible to distinguish between structurally- and capillary-trapped CO2 using time-lapse seismic monitoring of geological CO2 sequestration. Commercial reservoir simulation software was used to predict CO2 saturation in a saline aquifer over time. The output was combined with a rock physics model to calculate the elastic and seismic properties of the aquifer. As the seismic response depends on both fluid content and distribution, appropriate end-member fluid-distribution models were used to predict the possible range of seismic responses. We propose that different fluid-distribution models should be used for capillary- and structurally-trapped CO2 in a reservoir; the Hill average should be used for high, mobile CO2 saturations found during structural trapping whilst the Gassmann-Reuss average should be used for low, immobile CO2 saturations resulting from residual trapping. Far-offset seismic data was used to interpret reflections produced by the different trapping phases and cross-plotting was used to determine the trapping phase. Results indicate that structurally-trapped CO2 can be seismically imaged irrespective of fluid distribution and, importantly, a reflection may be generated off the interface between residually- and structurally-trapped CO2.

Refraction surveys are a well-established method of imaging subsurface velocities, both in terms of the deep crustal structure at global scales and in the shallow near surface. These surveys generally involve deploying an array of receivers on the surface (or water bottom) and recording arrivals from a seismic source initiated at or near the surface. © 2011 Society of Exploration Geophysicists.

The ability of time-lapse seismic surveys to monitor carbon dioxide sequestration is explored using a rock physics model. We investigate the effects of reservoir depth on the seismic response, and its ability to detect CO2 and distinguish saturation changes. We examine the effect of the fluid distribution on the magnitude of the seismic response and the potential to use this to distinguish different reservoir models of CO2 distribution. This analysis suggests that the presence of CO2 can easily be found using traditional seismic surveys, with some potential to distinguish CO2 saturation and distribution. © 2010, European Association of Geoscientists and Engineers.

A rock physics model was built to provide a link between geological modeling, reservoir engineering and the time-lapse seismic response to CO2 injection. This model was used to examine the influence of factors such as reservoir depth and fluid distribution on the seismic attributes. Depth was shown to be an important control on the magnitude of the response, with the largest change found at shallow depths. Therefore a tradeoff is required between the need to sequester CO2 deeply for safety and the ability of seismic surveys to detect CO2. Synthetic zero-offset seismic showed a detectable change in response for small amounts of CO2 but this is heavily dependent on fluid distribution. The zero-offset response shows limited success distinguishing higher saturation changes and Amplitude Variation with Offset (AVO) may be required to provide this information. The distribution of the fluids in the reservoir was shown to be a significant control on the magnitude of the P-wave response and it’s the relationship with saturation. This may allow reservoir engineers to distinguish between mobile and immobile CO2, enhancing the understanding of the trapping in the reservoir. The ability to do this is heavily frequency dependent and may require high frequency seismic data such as cross-well tomography.
