Reservoir characterization for the completion of the geothermal district heating system in Grado (NE Italy)

, 2013
As part of the Grado geothermal Project - Phase 2, an integrated gravity and seismic prospecting was recently conducted in downtown Grado Island (North Eastern Italy) and in the surrounding lagoon. The aim of this study was to characterize the carbonatic

Gibbs energy minimization thermodynamics for CO2 capture by aqueous amines: Conservation laws, concentration variables, and parameter consistency

The Canadian Journal of Chemical Engineering, EarlyView.
We clarify how Gibbs‐energy‐minimization models for aqueous‐amine CO2 capture fail when conservation constraints and concentration conventions are inconsistent. Exact standard‐state conversions and Reaktoro case studies show that P(CO2)‐loading fits can mask non‐unique parameters and wrong speciation, motivating complete water‐inclusive formulations ...

Renewable energy production potential of abandoned and orphaned oil and gas wells and sites

Environmental Research Letters
Abandoned and orphaned oil and gas well sites may be repurposed for wind and solar energy, while the wells themselves can be redeveloped for geothermal energy production.

When Managerial Values Become CSR Practices: A Configurational Analysis of Activation Conditions in SMEs

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Corporate social responsibility (CSR) engagement varies considerably across small and medium‐sized enterprises (SMEs), yet the conditions under which owner‐managers' values are associated with organisational practices remain insufficiently understood.

From CSR Claims to Legitimacy Gaps: Abductive Topic Modeling of Fashion Communication Across the Fashion Supply Chain

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Fiber‐Textile‐Apparel‐Retail (FTAR) firms communicate their fashion corporate social responsibility (fCSR) efforts to stakeholders to obtain operational legitimacy. However, little is known about the extent to which fCSR disclosures align with stakeholder expectations and sustainability principles.

Exploring wave propagation behaviors in rock: A grain‐based perspective on mineral structures

Deep Underground Science and Engineering, EarlyView.
This study investigates wave propagation in rock at the grain scale using a grain‐based model, revealing that mineral elastic modulus significantly influences wave attenuation while grain size and distribution have limited effects. A novel peak particle velocity attenuation prediction model is proposed and validated for grain‐scale wave propagation ...

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Advanced turbodrills for geothermal wells [PDF]

, 1978
The development of a new high-temperature, 350/sup 0/C advanced turbodrill for use in drilling geothermal wells is underway. Existing downhole drilling motors are temperature limited because of elastomeric degradation at elevated temperature.

Performance assessment of a potential underground thermal storage facility: Case study of the closed mine Prosper‐Haniel in the Ruhr coal mining area in Germany

Deep Underground Science and Engineering, EarlyView.
This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Modeling Highly Buoyant Flows in the Castel Giorgio: Torre Alfina Deep Geothermal Reservoir

Geofluids, 2018
The Castel Giorgio-Torre Alfina (CG-TA, central Italy) is a geothermal reservoir whose fluids are hosted in a carbonate formation at temperatures ranging between 120°C and 210°C. Data from deep wells suggest the existence of convective flow.
