Geological Hydrogen Storage: Geochemical Reactivity of Hydrogen with Sandstone Reservoirs

open access: yesACS Energy Letters, 2022
The geological storage of hydrogen is necessary to enable the successful transition to a hydrogen economy and achieve net-zero emissions targets. Comprehensive investigations must be undertaken for each storage site to ensure their long-term suitability ...

Relating pore fabric geometry to acoustic and permeability anisotropy in Crab Orchard Sandstone: A laboratory study using magnetic ferrofluid [PDF]

open access: yes, 2003
Pore fabric anisotropy is a common feature of many sedimentary rocks. In this paper we report results from a comparative study on the anisotropy of a porous sandstone (Crab Orchard) using anisotropy of magnetic susceptibility (AMS), acoustic wave ...

Edaphic Specialization in Tropical Trees: Physiological Correlates and Responses to Reciprocal Transplantation [PDF]

open access: yes, 2005
Recent research has documented the importance of edaphic factors in determining the habitat associations of tree species in many tropical rain forests, but the underlying mechanisms for edaphic associations are unclear.

Regional geothermal aquifer architecture of the fluvial Lower Cretaceous Nieuwerkerk Formation – a palynological analysis [PDF]

open access: yes, 2017
The primary challenge for efficient geothermal doublet design and deployment is the adequate prediction of the size, shape, lateral extent and thickness (or aquifer architecture) of aquifers.

Effect of water on sandstone's fracture toughness and frictional parameters: Brittle strength constraints

open access: yesInternational Journal of Rock Mechanics And Mining Sciences, 2021
Water presence causes a dramatic reduction of sandstone strength. Under compressive stress conditions, the strength of a rock sample is controlled by frictional parameters and the fracture toughness of the material.

The engineering geology of the Nottingham area, UK [PDF]

open access: yes, 2009
Nottingham was built near a crossing point on the River Trent in the East Midlands of England. Initially, the City developed on a low sandstone hill close to the north bank of the river, which provided a secure, well-drained location above the marshes ...
