The Influence of Microporous Cements on the Pore Network Geometry of Natural Sedimentary Rocks
Frontiers in Earth Science, 2019 We investigate the pore network geometry and permeability of six natural sandstones and carbonate rocks. Using 3D microtomographic images, we segment each rock sample into three phases: Solid matrix of grains, macropores containing void spaces, and a ...

4D Seismic Inversion to Changes in Pressure and Saturation Using Deep Learning
Geophysical Prospecting, Volume 74, Issue 4, May 2026.ABSTRACT This study presents a deep learning (DL)‐based 4D inversion approach for estimating dynamic reservoir properties—pressure change, water saturation change and gas saturation change—from 4D seismic data. The workflow reduces reliance on reservoir simulation‐driven static modelling stage in the sim2seis pipelines by using DL‐derived 3D ...

Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA
Groundwater, Volume 64, Issue 3, Page 335-349, May/June 2026.Abstract Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to learn about the distribution and controls on deeper groundwater. In sedimentary basins across the United

The brittleness index in hydraulic fracturing [PDF]
, 2015 We present a new definition of a brittleness index which is used as a criterion for candidate selection of rock intervals for hydraulic fracturing. The new index is a combination of material strength parameters and insitu stresses. It was derived from an

Evaluation of mineralogy per geological layers by Approximate Bayesian Computation
, 2019 We propose a new methodology to perform mineralogic inversion from wellbore logs based on a Bayesian linear regression model. Our method essentially relies on three steps.

Structural features of continental and oceanic lithospphere and their nature
Геофизический журнал, 2019 The deep geological and geophysical studies of the continents and oceans have revealed a number of well-defined new regularities in the structure of the crust and upper mantle that do not find a clear explanation in the modern geodynamic concepts.

Application of HCMM data to regional geologic analysis for mineral and energy resource evaluation [PDF]
Using a thermal-inertia mapping algorithm which provides greater discrimination capability than those in current use, a geologic features was detected in the Cabeza Prieta, Arizona, area.
