Stratigraphic

open access: yesEgyptian Journal of Petroleum, 2013
The stratigraphic distribution of the palynomorphs and particulate organic matter was studied in the subsurface Lower/Middle Cretaceous sections in Ii-26-1 and Ig-30-1 wells, located in north Western Desert of Egypt.

AdaHRBF v1.0: gradient-adaptive Hermite–Birkhoff radial basis function interpolants for three-dimensional stratigraphic implicit modeling [PDF]

open access: yesGeoscientific Model Development, 2023
Three-dimensional (3D) stratigraphic modeling is capable of modeling the shape, topology, and other properties of strata in a digitalized manner. The implicit modeling approach is becoming the mainstream approach for 3D stratigraphic modeling, which ...

Porosity and permeability prediction through forward stratigraphic simulations using GPM™ and Petrel™: application in shallow marine depositional settings [PDF]

open access: yesGeoscientific Model Development, 2021
The forward stratigraphic simulation approach is applied to predict porosity and permeability distribution. Synthetic well logs from the forward stratigraphic model served as secondary data to control porosity and permeability representation in the ...

Mammal Taphonomy in a Cave Deposit From Quaternary of Brazil

open access: yesFrontiers in Ecology and Evolution, 2022
In Brazil, the Quaternary caves of the Brazilian Intertropical Region (BIR) host important fossiliferous deposits of terrestrial vertebrates, whose fossil content is taxonomically well known.

Classifying basin‐scale stratigraphic geometries from subsurface formation tops with machine learning

open access: yesThe Depositional Record, 2021
Presented here is a transfer‐learning model for classifying basin‐scale stratigraphic geometries from subsurface formation tops. Support vector, decision trees, random forests, AdaBoost and K‐nearest neighbour classification models are evaluated to ...

Study on the Stratigraphic Framework and Main Control Factors of Hydrocarbon Formation in Thin Reservoirs of Carboniferous Clastic Rocks in Tahe Oilfield [PDF]

open access: yesE3S Web of Conferences, 2022
The Carboniferous Karashayi Formation in Tahe Oilfield is one of the most promising formations in the field of clastic rocks in Tahe Oilfield, which is rich in hydrocarbon resources, but the stratigraphic framework is unclear, which restricts the ...

Quaternary stratigraphic regionalization and comprehensive framework in Nanling and adjacent areas

open access: yes地质科技通报, 2021
The Quaternary sediments in the Nanling and adjacent areas are dominated by alluvial, eluvium and cave deposits, which have lacked of a unified stratigraphic and chronological framework.Based on the results of field survey and research on profiles, the ...

Stratigraphic noise and its potential drivers across the plateau of Dronning Maud Land, East Antarctica [PDF]

open access: yesThe Cryosphere, 2023
Stable water isotopologues of snow, firn and ice cores provide valuable information on past climate variations. Yet single profiles are generally not suitable for robust climate reconstructions. Stratigraphic noise, introduced by the irregular deposition,

Upper Eocene planktonic foraminifera from northern Saudi Arabia: implications for stratigraphic ranges [PDF]

open access: yesJournal of Micropalaeontology, 2021
The Rashrashiyah Formation of the Sirhan Basin in northern Saudi Arabia contains diverse assemblages of planktonic foraminifera. We examined the biostratigraphy, stratigraphic range and preservation of upper Eocene planktonic foraminifera.
