Understanding heat transfer in rock fractures is crucial for optimizing geothermal energy extraction, nuclear waste storage, and other subsurface engineering applications. In systems, the understanding of thermal behaviour fractured media still challenging, due to complexity fracture geometry, heterogeneous properties host rock, varying fluid flow dynamics influenced by temperature-dependent aperture. Considering that aperture shape can promote preferential transport fluids heat, several...

Abstract Interpretations of palaeodepositional environments are important for reconstructing Earth history. Only a few maps showing the Jurassic depositional in eastern Australia currently exist. Consequently, detailed understanding setting Gondwana is lacking. Core, wireline logs, two‐dimensional and three‐dimensional seismic from Precipice Sandstone Evergreen Formation Surat Basin have been used to construct evolution through Early Jurassic. The results indicate succession consists three...

The Lower Jurassic Precipice Sandstone and Evergreen Formation are an important prospective reservoir–seal pair for CO 2 storage in the Surat Basin, Australia. However, there is little seismic well data to constrain reservoir modelling best notional injection area. To test likely performance, three contrasting sector-scale static models were built capture range of geological uncertainty facies distribution properties. These considered sectors Basin with different palaeogeographical...

Abstract. Isotopic fractionation of evaporating waters has been studied constantly in recent decades, particularly because it enables calculation both the volume water evaporated from a body and isotopic composition its source water. We stable isotopy an artificial pan filled with sub-humid environment, order to put into practice operational method for estimating time since disconnection riverine pools when these are sampled quality aquatic life. Results indicate that: (i) about 70 % had...

Isotopic fractionation of evaporating waters has been studied constantly in recent decades, particularly because it enables calculation both the volume water evaporated from a body and isotopic composition its source water. We stable an artificial pan filled with subject to total evaporation sub-humid environment, order put into practice operational method for estimating time since disconnection riverine pools when these are sampled quality aquatic life.

Large high-speed railway (HSR) networks are planned for the near future to accomplish increased transport demand with low energy consumption. However, trains produce unknown avian mortality due birds using and being unable avoid approaching trains. Safety logistic difficulties have precluded until now estimation in railways through carcass removal, but information technologies can overcome such problems. We present results obtained an experimental on-board system record bird-train collisions...

SummaryThe Surat Basin is one of the most prospective onshore basins in Australia for CO2 storage. The Precipice Sandstone and Evergreen Formation have been appraised their feasibility as a future storage reservoir-seal pair. Here we will focus on predicted CO2-water-rock reactions. These predictions rely mineral porosity data from drill core. Data were obtained northern two southern regions Basin. region was more rich. well core sparse with exception Moonie oil Field. Additional samples...

The stratigraphy of the Surat Basin, Queensland, has historically been sub-divided by formation and unit nomenclature with a few attempts other authors to apply sequence existing boundaries. At local- field-scale, lithostratigraphy may be able represent well, but at regional-scale, lithostratigraphic units are likely diachronous. To date, this lithology-driven framework does not accurately reflect time relationships in sub-surface. An entirely new integrated methodological approach,...

In three radial models (typical of the Trelinga-1, Overston-1 and Moonie-39 wells) with boundaries placed at different distances, injection rates 2 million tonnes per annum (Mt/a) cannot be sustained. larger sector models, (with parameters typical these 2Mt/a is sustained in Precipice Sandstone (Surat Basin), but reduces to 1.2Mt/a Showgrounds (Bowen Basin). Plume footprints overpressures range 10- 15 km 35-75 bar, respectively. Baffles cause maximum overpressure CO2 accumulation occur...

<p>The hydrology of non-perennial (temporary) rivers under climate change (UPH 3) affects not only dry regions but could affect all climates, because most the catchment headwaters already have (or will have) temporary regimes. Most undergo a pools phase when surface flow ceases water remains in disconnected pools. These offer many ecosystem services, such as provision refuges for aquatic species. Nevertheless, this is poorly known gauging stations or hydrological models do...

<p>Temporary rivers, characterized by shifts between flowing water, disconnected pools and dry periods, represent over 50% of the world’s river network future climatic projections suggest their increase. These rivers are understudied, especially when only remain, because gauging stations or hydrological models do not inform what happens after cessation flow. In addition, most biological indicators for water quality designed waters adequacy temporary is...
