Seismic attribute-assisted structure analysis of the Mackay dome transpressional system, Bighorn basin, southern Montana: Evidence for reservoir compartmentalization
… divide it into a more segmented reservoir. The seismic attributes most extreme curvature, variance, and ant tracking were applied to the Greybull reservoir in order to delineate bounding and segmenting faults of the reservoir. These attributes identified minor faults that divide the reservoir …

Structure Segmentation and Transfer Faults in the Marcellus Shale, Clearfield County, Pennsylvania: Implications for Gas Recovery Efficiency and Risk Assessment Using 3D Seismic Attribute Analysis
… through the aid of both traditional and advanced seismic attributes including variance, curvature, ant tracking, and waveform model regression. Through the integration of well log interpretations and seismic data, a detailed assessment of structural discontinuities that may decrease the recovery …

Seismic and Well Log Attribute Analysis of the Jurassic Entrada/Curtis Interval Within the North Hill Creek 3D Seismic Survey, Uinta Basin, Utah, A Case History
3D seismic attribute analysis of the Jurassic Entrada/Curtis interval within the North Hill Creek (NHC) survey has been useful in delineating reservoir quality eolian-influenced dune complexes. Amplitude, average reflection strength and spectral decomposition appear to be most useful in locating …

Mapping Middle Paleozoic Erosional and Karstic Patterns with 3-D Seismic Attributes and Well Data in the Arkoma Basin, Oklahoma
<p>Newly available industry well data and seismic attribute analysis reveal that late Ordovician-early Devonian Hunton Group strata are more widespread (i.e., not removed by mid-Devonian erosion) in the central and southern portions of the Arkoma Basin in eastern Oklahoma than previously thought. …

AN APPLICATION OF FLUID MOBILITY ATTRIBUTE FOR PERMEABILITY PROGNOSIS WITHIN THE MIDDLE JURASSIC SEDIMENTS IN THE SOUTHERN PART OF WESTERN SIBERIA
… For solving this problem, the dataset of the 3D seismic and well data (core samples, well logs, and formation testing) was utilized. The core measurements of the permeability at room conditions show a weak anisotropy in orthogonal directions and a correlation with porosity. The porosity values in …

Modeling Offset-Dependent Reflectivity for Time-Lapse Monitoring of Water-Flood Production in Thin-Layered Reservoirs
Seismic time-lapse monitoring of production is an important tool used to efficiently drain a hydrocarbon reservoir. Repeat seismic surveys may be used, because the seismic method is sensitive to the reservoir fluid. A prominent seismic attribute is the reflectivity (or amplitude) as a function of …
