Uncertainty Analysis of Otway CO2 Sequestration Project
A viable means of CO2 reduction in the atmosphere is to capture and concentrate CO2 from large point sources such as power plants and petroleum refineries and store it by underground injection. The main concern for commercial scale CO2 sequestration in geologic formations is the uncertainties associated with this process. The risks involved in different stages of a CO2 sequestration project are...
متن کاملComparison of seismic and borehole data at the same scale
Well-log measurements and seismic measurements should be compared at the same scale. The conversion of highly detailed borehole data into less detailed seismic data has to be done in a specific way considering conclusions from scaling analysis. One has to be careful with the differentiation to convert borehole acoustic impedance into reflectivity. In addition coarsening has to occur in such a w...
متن کاملSeismic Waves in a Borehole - a Review
The propagation of seismic waves in an open borehole is reviewed. The principal wave types are the refracted P and S waves and the two guided waves pseudo-Rayleigh and Stoneley. The dispersion properties of the gUided waves are analyzed. An efficient method of computing synthetic microseismograms is described. The relative effects of the borehole. fluid and formation properties on the propagati...
متن کاملCased Borehole Effect on Downhole Seismic Measurements
Approximate and exact formulations are presented for the interaction of an incident wave with a cased borehole. In the approximate method, the borehole coupling theory is used to compute pressure in the fluid at a low frequency. The results are simple and explicit. They are useful in the study of cased borehole coupling and as well as borehole radiation. In the exact method, elastic potentials ...
متن کاملblending and deblending in seismic data acquisition and processing
in the current seismic data acquisition techniques, sources are fired with large time intervals in order to avoid interferences between the responses of successively firing sources, measured by the receivers. this leads to a time-consuming and expensive survey. theoretically the waiting time between two successively firing sources has to be infinite, since the wavefield never vanishes completel...
