Elsevier B.V.
, 2021 , Article)
Although the Middle East's carbonate reservoirs were the first and most studied rocks in the world, Middle Eastern shale reservoirs are still poorly understood compared with other unconventional formations in the US. We ...
Microbially influenced formation of anhydrite at low temperature
(
Elsevier B.V.
, 2023 , Article)
Calcium sulfate minerals are abundant in nature – on Earth and on Mars – and important in several fields of material sciences. With respect to gypsum and bassanite, anhydrite represents the anhydrous crystalline phase in ...
Characterizing fracture toughness using machine learning
(
Elsevier B.V.
, 2021 , Article)
The existing models for fracture toughness characterization based on nanoindentations that account for the fracture length are limited to simple (ideal) geometries that are absent in shales. The present study proposes two ...
