Petrofacies characterization using best combination of multiple elastic properties

Journal of Petroleum Science and Engineering, 2019
Abstract Elastic properties such as P-impedance and the ratio of P- to S-wave velocity are key features for linking well log data to seismic data for reservoir characterization. Crossplotting methods from well log data are commonly applied to delineate the distribution of petrofacies on the seismic volume.

Petrologic Intervals and Petrofacies in the Great Valley Sequence, Sacramento Valley, California

Bulletin of the Geological Society of America, 1972
The Great Valley Sequence of Upper Jurassic to Upper Cretaceous strata is composed of clastic detritus eroded from the Sierran-Klamath belt, which was the site of a late Mesozoic magmatic arc. The sequence accumulated mainly as a prismatic wedge of turbidites in an asymmetric trough within the arc-trench gap.

Sandstone petrofacies in the Cenozoic High Plains sequence, eastern Wyoming and Nebraska

Bulletin of the Geological Society of America, 1976
Cenozoic stream systems east of the Laramie Range in Wyoming and Nebraska and their headwater areas in the Laramie and Front Ranges, the Hartville uplift, and North Park basin are better defined by stratigraphic and geographic distribution of sandstone petrofacies in the Cenozoic High Plains sequence than by stratigraphic parameters or paleocurrent ...

Petrofacies and Petrologic Evolution of the Late Cretaceous Fore-Arc Basin, Northern and Central California

Journal of Geology, 1978
Sandstone within the Late Cretaceous forearc basin of northern and central California displays vertical and horizontal compositional variations that facilitate stratigraphic correlation and reveal provenance characteristics. Four Sacramento Valley petrofacies, three San Joaquin petrofacies, and two late Late Cretaceous petrofacies that occur in both ...

Petrofacies classification using machine learning algorithms

Geophysics, 2020
ABSTRACT Carbonate reservoirs represent a large portion of the world’s oil and gas reserves, exhibiting specific characteristics that pose complex challenges to the reservoirs’ characterization, production, and management. Therefore, the evaluation of the relationships between the key parameters, such as porosity, permeability, water ...

Sedimentation in the Chile Trench; petrofacies and provenance

Journal of Sedimentary Research, 1987
Abstract The Chile Trench study area extends over 2,000 km along the Andean continental margin, from 23 degrees S to 42 degrees S latitude. The QFL composition of Chile Trench sands encompasses the average compositions of modern sands from strike-slip, continental arc, oceanic backarc, and oceanic forearc types of active margins ...

The effect of sampling scale on actualistic sandstone petrofacies

Sedimentology, 1993
ABSTRACTEmpirical correlations between plate tectonic setting and sand/sandstone composition have been the basis for large scale petrological models. These models do not explicitly treat sampling scale. Four areas from the western USA with diverse tectonic settings and rock types provide a natural laboratory for sampling sand at three different scales:

Sandstone petrofacies prediction to characterize permeability for Postle Field, Oklahoma

SEG Technical Program Expanded Abstracts 2009, 2009
Summary A permeability model is being developed for Postle Field. The area of study is located in Texas County, Oklahoma. The biggest challenge at Postle Field is the heterogeneity within the reservoir, especially the presence of a high permeability zone interpreted as a basal lag and its repercussions in terms of field performance under a CO2 ...

Petrofacies for the prediction of NOA content in rocks: application to the “Gronda di Genova” tunneling project

Bulletin of Engineering Geology and the Environment, 2019
Realization of large geo-engineering projects in rocks containing naturally occurring asbestos (NOA) must address several crucial geo-environmental issues, including the design of the construction site, the enforcement of health protection measures and the environmentally responsible spoil management.
