THE MICROFACIES, SEQUENCE STRATIGRAPHY AND GENESIS OF THE UPPER DEVONIAN PHOSPHORITES IN THE NORTH OF KERMAN, SE IRAN

Rivista Italiana di Paleontologia e Stratigrafia, 2020
This research focuses on the microfacies, sequence stratigraphy and genesis of the upper Devonian phosphate-rich deposits in the Kerman province, SE Iran. These deposits are investigated in the Sarashk and Hutk sections, which are the most complete upper

TAMNet: Temporal and adaptive‐frequency network with MixStyle for cross‐region oil and fluid production forecasting

Deep Underground Science and Engineering, EarlyView.
This paper presents temporal and adaptive‐frequency network with MixStyle (TAMNet), a deep time‐series modeling framework for accurate and robust multi‐well oil productivity forecasting. TAMNet integrates transformer and long short‐term memory architectures to capture both short‐ and long‐term temporal dependencies, enhanced by a temporal gate unit ...

Sequence stratigraphy in Proterozoic successions

Geology, 1988
Sedimentological logging and facies mapping have been used to identify depositional sequences bounded by subtle but regionally persistent unconformities in rocks of Proterozoic age in the western United States, South Australia, and northwestern Canada. We conclude from these studies that the sequence stratigraphic approach is of considerable importance

Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Periodic Law Patterns of Sequence Stratigraphy

Earth Science Informatics, 2023
AbstractBased on the current theory of sequence stratigraphy, this study employs stillstand normal regression (SNR) to replace the method of highstand normal regression (HNR) to establish shoreline trajectory and sediment supply models of off-lap and onlap-type sequences, respectively.

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin

Deep Underground Science and Engineering, EarlyView.
The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

Sedimentary Characteristics and Lithological Trap Identification of Distant Braided Delta Deposits: A Case on Upper Cretaceous Yogou Formation of Termit Basin, Niger

E3S Web of Conferences, 2018
Lithological trap identification in thin sand and thick shale layers is still a challenge for hydrocarbon exploration. Based on the high-resolution sequence stratigraphy theory and the establishment of high-resolution sequence stratigraphy framework with

NEW OUTCROP AND SUBSURFACE DATA IN THE TERTIARY PIEDMONT BASIN (NW-ITALY): UNCONFORMITY-BOUNDED STRATIGRAPHIC UNITS AND THEIR RELATIONSHIPS WITH BASIN-MODIFICATION PHASES

Rivista Italiana di Paleontologia e Stratigrafia, 2009
This paper deals with the regional stratigraphy around the Alps-Apennines junction during late Eocene-Miocene. The basin-fill architecture and its relation to changes in structural style were deciphered through the integration of subsurface and outcrop ...

Phosphate and fluoride removal options for Hanford high‐level waste sludge processing

Environmental Progress &Sustainable Energy, EarlyView.
Abstract High‐phosphate and high‐fluoride sludges represent some of the most challenging waste streams within the Hanford High‐Level Waste (HLW) inventory due to solubility constraints, impacts on glass loading, and corrosion risks during vitrification.

Development characteristics of the third-order sequence of Upper Devonian–Lower Carboniferous shore-mixed shelf in Tarim Basin, NW China

Petroleum Exploration and Development, 2019
Based on the study of stratigraphic sedimentary facies of the prototype sedimentary basin formed in the Late Devonian to Permian Period in the Tarim Basin, the prototype sedimentary basin are divided into five order sequences according to the theory of ...
