Deep Underground Science and Engineering, EarlyView.This work integrates 5 years of field data from the Aquistore CCS project with a non‐isothermal THM modeling framework to explain how cold CO2 injection alters injectivity over time. The study shows that sustained cooling near the wellbore reduces effective stresses, promotes tensile micro‑cracking, and leads to semi‑reversible permeability enhancement

Deep Underground Science and Engineering, EarlyView.The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...

Energy Science &Engineering, EarlyView.Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Geothermal Reservoir Engineering
Eos, Transactions American Geophysical Union, 1983 The goal of the authors in writing Geothermal Reservoir Engineering was to bring together all the currently available information on geothermal reservoir engineering published before late 1981. The available information not only includes geothermal publications but also related publications in the areas of petroleum reservoir engineering and ...

Radon in geothermal reservoir engineering [PDF]
Geothermics, 1977 Abstract Radon has been shown to have potential as a tracer in the study of geothermal reservoirs. The combination of its physical and nuclear properties and its emanation and transport in geothermal fluids makes several types of time and concentration measurements useful for studies of fracture permeability and porosity and flow characteristics in ...

Energy Science &Engineering, EarlyView.Formed ~1.4 Ga, the carbonate reservoir of the Jixian System is a key geothermal reservoir in northern China. Differential basin–mountain evolution since the Cenozoic led to distinct reservoir‐forming histories; consequently, this same reservoir shows marked productivity contrasts between intramontane basins and the large rift Bohai Bay Basin ...

Analysis of production decline in geothermal reservoirs [PDF]
, 1980 The major objective of the Decline Curve project were to 1. Test the decline analysis methods used in the petroleum industry on geothermal production data, 2. Examine and/ or develop new analysis methods, 3. Develop a standard operating procedure for analyzing geothermal production data.

Energy Science &Engineering, EarlyView.Higher compressive strength in sandstone fractures leads to smoother surfaces, smaller apertures, and more contact, which reduce transmissivity but increase the critical pressure gradient for nonlinear flow initiation. ABSTRACT The correlation between rock compressive strength and fracture roughness represents a significant area of research within the ...

Geothermal resource assessment for Hawaii [PDF]
, 1979 The preliminary phase of a geothermal resource assessment program for the State of Hawaii has been completed. Several locations on all the major islands of the Hawaiian chain have been identified as potentially having a geothermal reservoir within a few ...
