Near - surface characterization of sediments of the Sokoto group exposed around Wamakko area, Northwestern Nigeria: an integrated approach

open access: yesGeology, Ecology, and Landscapes, 2021
An integrated approach involving sedimentological and geophysical studies was carried out to characterize the surface and subsurface geology of part of the southwestern Iullemmeden basin (Sokoto Basin, North-western Nigeria).

Seismic facies recognition based on prestack data using deep convolutional autoencoder [PDF]

open access: yesGEOPHYSICS, 2018, 83(3): A39-A43, 2017
Prestack seismic data carries much useful information that can help us find more complex atypical reservoirs. Therefore, we are increasingly inclined to use prestack seismic data for seis- mic facies recognition. However, due to the inclusion of ex- cessive redundancy, effective feature extraction from prestack seismic data becomes critical.

Contrasting carbonate depositional systems for Pliocene cool-water limestones cropping out in central Hawke's Bay, New Zealand [PDF]

open access: yes, 2004
Pliocene limestone formations in central Hawke's Bay (eastern North Island, New Zealand) accumulated on and near the margins of a narrow forearc basin seaway within the convergent Australia/Pacific plate boundary zone.

Palaeolimnology of Lake Sapanca and identification of historic earthquake signals, Northern Anatolian Fault Zone (Turkey) [PDF]

open access: yes, 2009
Lake Sapanca is located on a strand of the Northern Anatolian Fault Zone (NAFZ, Turkey), where a series of strong earthquakes (Ms >6.0) have occurred over the past hundred years. Identifying prehistoric earthquakes in and around Lake Sapanca is key to a

Hydrochemical evaluation of spring's water in Mila Wilaya, North-East Algeria

open access: yesWater Practice and Technology, 2023
Springs are natural outflows of groundwater to the surface, enabling to understand the processes of their mineralization; contact with rocks modifies their chemical composition, a combination that is expressed in hydrochemical facies, which are ...

Anatomy and Sequence Architecture of the early Post-Rift in the Neuquén Basin (Argentina): A Response to Physiography and Relative Sea-level Changes [PDF]

open access: yes, 2013
A detailed architectural and sequence stratigraphic analysis was carried out in the early-post-rift succession of central Neuque´n Basin (Middle Jurassic Cuyo Group), integrating outcrop and subsurface information from a 3,000 km2 area.

Towards a Robust Parameterization for Conditioning Facies Models Using Deep Variational Autoencoders and Ensemble Smoother [PDF]

open access: yes, 2018
The literature about history matching is vast and despite the impressive number of methods proposed and the significant progresses reported in the last decade, conditioning reservoir models to dynamic data is still a challenging task. Ensemble-based methods are among the most successful and efficient techniques currently available for history matching.

CPT Parameters of Loess Subsoil in Lublin Area

open access: yesApplied Sciences, 2021
Loess soils were created by the wind transporting particles with later or in parallel occurred protogenetic, syngenetic and epigenetic processes. As a result, various genetic processes affected loesses strength and deformability characteristics.
