Analyzing rock and underground layers is known as drill core lithology. The extracted core
sample helps not only in exploring the core properties but also reveals the lithology of the …

Ascertaining the positions of geological boundaries serves as a cornerstone in the
characterization of shale reservoirs. Existing methods heavily rely on labor-intensive manual …

X-ray computerized tomography (CT) images as digital representations of whole cores can
provide valuable information on the composition and internal structure of cores extracted …

Carbon capture and storage (CCS) is an attractive alternative to reduce the concentration of
greenhouse gases in the atmosphere with the objective of preventing further increases in …

Reservoir characterization requires accurate prediction of multiple petrophysical properties
such as bulk density (or acoustic impedance), porosity, and permeability. However, it …

Supervised learning algorithms can be employed for the automation of time-intensive tasks,
such as image-based rock classification. However, labeled data are not always available …

Reliable estimation of petrophysical properties can be challenging, especially in geological
formations with rapid variation in the spatial distribution of rock components. The spatial …

This paper presents a log-based workflow that provides the cm-scale vertical resolution well
framework capable of capturing the level of heterogeneity often present in mudstones. The …

We have described an algorithm to perform automatic dip picking on borehole images. One
key element of our method is a statistical validation, based on the a contrario theory, which is …

Sedimentary rocks display complex spatial distribution of both pore space and solid
components, impacting the directional dependence of physical phenomena such as …
