The 3D seismic data collected on LD--TST structure are comprehensively interpreted and used by wave impedance inversion,seismic facies analysis and seismic attribution analysis,by which the reserves are recalculated and a suggestion of 5 appraise wells is made in combination with the data of the discovery well (LD--TST-1).
Research result leads to the conclusion that the seismic property of SH wave can be derived from P-SV wave, and that slightly-revised AVO analysis software for compressional wave can also be applied to AVO analysis of shear wave.
This feasibility study analyzes the possible time-lapse seismic attribute spatial distribution using dynamic data and the reservoir model to determine the optimum time to acquire a new seismic survey.
Petroleum geophysicists recognize that many parameters related to oil and gas reservoirs are predicted using seismic attribute data.
In this paper we discuss a petrophysical analysis method for the selection and application of higher sensitivity seismic attribute parameters to improve the ability to discriminate fluid and lithology.
At several locations, seismic attribute maps reveal detailed images of flat spots, inferred to represent gas-water interfaces.
Although the results from a single gather are non-unique, the initial model derived here provides a self-consistent starting point for a more complete seismic attribute inversion for the velocity and attenuation structure.
Information feedbacks occurred between the pre-stack and post-stack processes so as to improve the accuracy in utilization of data and avoid pitfalls in seismic attributes.
Seismic attributes optimization and application in reservoir prediction
However, how best to optimize the seismic attributes, predict the character of thin sandstone reservoirs, and enhance the reservoir description accuracy is an important goal for geologists and geophysicists.
This paper represents an attempt of analysing the amplitude versus offset (AVO) behaviour and specific seismic attributes of sedimentary structures from the Porcupine Basin, SW of Ireland.
The area of blanking was defined using the seismic attributes instantaneous amplitude and similarity.
