Dolomite geochemistry of the Cambrian Longwangmiao Formation, eastern Sichuan Basin: Implication for dolomitization and reservoir prediction

Petroleum Research, 2017
Based on petrology and mineralogy, the geochemical characteristics of dolomite in the Cambrian Longwangmiao Formation in the eastern Sichuan Basin, were carried out. Results showed that dolomites mainly occurred in the middle and upper parts of Longwangmiao Formation, with most commonly as a crystalline dolomite and less commonly as a gain dolomite ...

How Much Physics Should a Neural Network Know? Thermodynamics‐Informed Neural Networks for Rock Constitutive Modeling With Epistemic Uncertainty

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Machine learning offers a flexible route to constitutive modeling, with two emergent questions for geoscience applications: what level of thermodynamic constraint should be embedded in the network architecture, and how should predictive uncertainty be quantified when extrapolating from laboratory to field conditions? We address both challenges

A New Experimental Design to Measure Second‐ and Third‐Order Anisotropic Rock‐Stiffness Coefficients Using a Single‐Rock Sample

Geophysical Prospecting, Volume 74, Issue 8, October 2026.
ABSTRACT We developed a new experimental setup for measuring and modelling stress‐induced anisotropy and nonlinearity in cylindrical rock samples. Multidirectional ultrasonic velocity measurements were conducted under laboratory conditions and during triaxial‐stress testing to capture dynamic rock properties. This is done by placing endcap transducers (
