Image logs provide important information on lithology, sedimentary textures, paleoflow
directions, fractures and in situ stress analysis. Lacking of criteria used for establishing the …

Abstract The deeply buried (5.5–7.1 km) Lower Cretaceous Bashijiqike sandstones are
important fractured reservoirs in the Kuqa depression. In these high temperature-high …

Correct selection and interpretation of proxies are key to cyclostratigraphic research;
however, the uncritical use of geophysical logs as proxies for cyclostratigraphy could be …

Machine-learning algorithms have been used by geoscientists to infer geologic and physical
properties from hydrocarbon exploration and development wells for more than 40 years …

Rock mechanical properties play a key role in the optimization process of engineering
practices in the oil and gas industry so that better field development decisions can be made …

Borehole electrical image log with core-like presentation is an efficient way to conduct
sedimentary description in the subsurface. The key is to set up a series of geological …

Present-day stress state is significant for petroleum industry and prediction of stress-related
geohazards. The Kelasu Belt, located between Southern Tianshan and the bank-land of the …

Drilling cores, the most direct and accurate first-hand data reflecting the subsurface
geological information, are of unclear orientation for most boreholes. The image feature …

Machine-learning algorithms have long aided in geologic property prediction from well-log
data, but are primarily used to classify lithology, facies, formation, and rock types. However …

This study aimed at the magnetostratigraphic age assignment of a 100-m-long drill core
penetrating the Miocene lake sediments of the intramontane Turiec Basin of the Inner …
