[Dynamic enhanced recovery technologies]. Quarterly technical report, August 1992--October 1993
This paper has presented the investigation of the mechanism of geopressure occurrence, the transition of elastic properties from the hydrostatic pressured formation to the geopressured formation, and finally, a novel seismic amplitude analysis technique to map the top-of-geopresure surface. The successful application of our new technique to the Pleistocene, offshore Louisiana, Gulf of Mexico has again demonstrated that seismic attributes analyses are of importantance in the hydrocarbon exploration. There are three parts in this paper corresponding to the above discussed topics: Part I discusses mechanisms of geopressuring, and the effects of changing porosity, pressure, and fluid saturation on the elastic properties; Part II investigates the controlling factors in the geopressure transition zone, their seismic responses, and theoretical derivations of our new prediction method; and Part III demonstrates the application of the proposed method to the Pleistocene, Offshore Louisiana, Gulf of Mexico, the prediction discrpepancy between the seismic predicted top-of-geopressure and that dericed from 145 well logs, and finally, the importance of this hydrodynamic surface.
