Mapping of the West Yakut barrier reef in the junction zone of the Vilyui syneclise and Aldan anteclise using electro-facies analysis

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2021
The aim of the study was to test the method of electro-facies analysis for mapping reef structures in the conditions of the junction of the Vilyui syneclise and Aldan anteclise.

Effect of the thermal gradient variation through geological time on basin modeling; a case study: The Paris basin. [PDF]

open access: yes, 2005
Many studies investigated the thermal modeling of the Paris basin for petroleum interests during the 1970s. Most of the softwares developed by oil companies or research centers were based on the assumption of a constant thermal gradient. In order to take

Deltas: New paradigms

open access: yesThe Depositional Record, Volume 10, Issue 5, Page 600-636, November 2024.
This paper discusses some new paradigms concerning the origin and significance of deltas and their deposits. It proposes a broader definition of deltas that takes into account the importance of sediment‐laden fluvial discharges in controlling deltaic sedimentation.

Integrated petrophysical study to validate water saturation from well logs in Bahariya Shaley Sand Reservoirs, case study from Abu Gharadig Basin, Egypt

open access: yesJournal of Petroleum Exploration and Production Technology, 2020
Water saturation is a key parameter in evaluating oil and gas reservoirs and calculating OIIP and GIIP for petroleum fields. The late Cretaceous Bahariya reservoir contains variable amounts of clay minerals.

Seismic expression of miocene carbonate platform and reservoir characterization through geophysical approach: application in central Luconia, offshore Malaysia

open access: yesJournal of Petroleum Exploration and Production Technology, 2021
A substantial proportion of proven oil and gas reserves of the world is contained in the carbonate reservoir. It is estimated that about 60% of the world’s oil and 40% of gas reserves are confined in carbonate reservoirs.

Multiscale evaluation of a thin-bed reservoir [PDF]

open access: yes, 2021
A thin-bed laminated shaly-sand reservoir of the Miocene formation was evaluated using two methods: high resolution microresistivity data from the XRMI tool and conventional well logs.

Field Investigation of Serpentinite With Induced Polarization and the K‐Means Clustering Technique

open access: yesGeophysical Research Letters, Volume 51, Issue 18, 28 September 2024.
Abstract We performed a field induced polarization survey at Rocher du Chateau in the French Alps. This site is characterized by the presence of ophiolites with an outcrop of serpentinites. Serpentinite is characterized by high resistivity (∼0.5–10 kΩ m) and high chargeability (∼20–400 mV V−1) values.

Data report: logging while drilling data analysis of Leg 171A, a multivariate statistical approach [PDF]

open access: yes, 2000
In the northern Barbados accretionary wedge, several Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) legs (DSDP Leg 78 and ODP Legs 110, 156, and 171A) targeted the décollement and the seaward extension of the décollement, the proto ...

Evaluation of hydraulic conductivity in shallow groundwater formations: a comparative study of the Csókás’ and Kozeny–Carman model [PDF]

open access: yes, 2015
The Kozeny–Carman equation has achieved widespread use as a standard model for estimating hydraulic conductivity of aquifers. An empirically modified form applicable in shallow formations called Csókás’ formula is discussed, which is based on the ...
