Sedimentary hints of seismic reflectors into an oolithic carbonate analogue reservoir study case on the “Oolithe Blanche” (Burgundy, France)

BSGF - Earth Sciences Bulletin
Although 3D and even 4D seismic imaging have advanced significantly, some acoustic patterns in carbonate reservoirs remain poorly understood. Diagenetic effects are still largely overlooked in interpreting reflectors within these complex sedimentary ...

Electroclinical phenotypes—genetic characterization of developmental and epileptic encephalopathies in a cohort study

Epileptic Disorders, EarlyView.
Abstract Objective Developmental and epileptic encephalopathies (DEEs) are characterized by refractory seizures and frequently recurring epileptic activity with neurodevelopmental delay or regression that usually begin in early life. We aimed to define the relationship between electroclinical features and etiology, as well as the genotype–phenotype ...

Localization and further extraction of residual recoverable oil reserves in low-permeability sandstone reservoirs with chaotic oblique layering in a late-stage field: a case study of the Achimov sequence

Известия высших учебных заведений: Нефть и газ
Achimov sequence is characterized by high heterogeneity and low reservoir properties. Development of Achimov sequence occurs using horizontal wells with multistage hydraulic fracturing.

Evaluation of Drillability of the Mahu Conglomerate Formation in Xinjiang, China

Energy Science &Engineering, EarlyView.
This graphical abstract illustrates the workflow for developing an optimized prediction model using measurement while drilling (MWD) data. A total of 90 MWD cases are divided into a training set (80%) and a test set (20%). Four logging‐while‐drilling parameters—compensation density, acoustic travel time, resistivity, and neutron porosity—are selected ...

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...
