Abstract This study examines the impact of flooding on and wave velocities in Upper Assam Basin. Laboratory experiments were conducted 15 consolidated sandstone cores from Naharkatiya Rudrasagar reservoirs ( m depth) one unconsolidated sand pack (lightweight proppant, Houston, USA). Samples, with porosities ranging 8.03% to 47.00%, saturated before injection. Results indicate reduces (compressional velocity, m/s) by 4–11% samples over 25% pack, less pronounced but significant reductions (shear m/s). These changes are influenced pore pressure, porosity, temperature. Higher pressure amplifies velocity increasing fluid density altering bulk modulus. In sandstones, diminish whereas sands exhibit greater sensitivity due their lower Theoretical analyses confirm that observed laboratory settings representative situ conditions. findings highlight value time‐lapse seismic monitoring tracking plumes optimizing enhanced oil recovery strategies. The integration techniques improves reservoir management while supporting carbon sequestration initiatives Basin similar geological settings.

The increase in the exploration of renewable energy sources intensifies need for efficient storage solutions to mitigate inherent intermittence these sources. Among available technologies, cryogenic (CES) systems stand out as a major and promising technology due their high scalability, efficiency, potential integration with other systems. This paper deals approaches, focused on Liquid Air Energy Storage (LAES). Several topics are addressed, including characterization CES systems, working principle, special relevance efficiency temperature/entropy diagram, conception technical challenges, design, construction CES. LAES demonstrates efficiencies ranging from 45% 70%, potentially reaching up 75% complementary capital costs 900 EUR/kW 1750/EUR/kW. Carbon dioxide (CO2)-based while more energy-efficient (40% 60%), face significant barriers infrastructure costs. Additionally, hybrid configurations that combine advanced thermal cycles waste heat management achieve between 55% 80%, showing adaptability complex scenarios. In comparison alternatives such batteries Compressed (CAES), despite economic technological limitations, have role global transition, particularly anticipated advancements will enhance competitiveness viability.
