WebApr 10, 2024 · Conventional inversion methods are not highly effective at predicting reservoir thickness, and cannot keep up with current demands. Our aim is to demonstrate how seismic data can be used to forecast coal thickness, as well as the distribution and orientation of subtle structures that may be linked to enhanced permeability zones. WebJan 12, 2016 · Variation of reservoir physical properties can cause changes in its elastic parameters. However, this is not a simple linear relation. Furthermore, the lack of …

Webof inland Case-2 waters and evaluating reservoir eutrophication. The current study took the Dashahe Reservoir, a typical inland Case-2 water body located in the coastal area of Guangdong province, South China, as an example. An inversion model based on a BP neural network (the BP inversion model) was built based on Landsat8 satellite remote Geostatistical inversion integrates high resolution well data with low resolution 3-D seismic, and provides a model with high vertical detail near and away from well control. This generates reservoir models with geologically-plausible shapes, and provides a clear quantification of uncertainty to assess risk. … See more In geophysics (primarily in oil-and-gas exploration/development), seismic inversion is the process of transforming seismic reflection data into a quantitative rock-property description of a reservoir. Seismic inversion … See more Inversion includes both seismic field data and well data, where well data serves to add the high frequency below the seismic band and to … See more An example of a post-stack seismic resolution inversion technique is the constrained sparse-spike inversion (CSSI). This assumes a limited number of reflection coefficients, with larger amplitude. The inversion results in acoustic impedance … See more Amplitude versus offset (AVO) (AVA) geostatistical inversion incorporates simultaneous AVO (AVA) inversion into the geostatistical … See more Geophysicists routinely perform seismic surveys to gather information about the geology of an oil or gas field. These surveys record sound waves which have traveled through the layers of … See more All modern seismic inversion methods require seismic data and a wavelet estimated from the data. Typically, a reflection coefficient series from a well within the boundaries of the seismic survey is used to estimate the wavelet phase and … See more Pre-stack inversion is often used when post-stack inversion fails to sufficiently differentiate geologic features with similar P-impedance … See more how to use timeit to time functions python
