The Economics of Geological CO2 Storage and Leakage

Online Monitoring of Geological CO2 Storage and Leakage Based on Wireless Sensor Networks

A remote online carbon dioxide (CO2) concentration monitoring system is developed, based on the technologies of wireless sensor networks, in allusion to the gas leakage monitoring requirement for CO2 capture and storage. The remote online CO2 monitoring system consists of monitoring equipment, a data center server, and the clients. The monitoring equipment is composed of a central processing un...

Impact of relative permeability hysteresis on geological CO2 storage

[1] Relative permeabilities are the key descriptors in classical formulations of multiphase flow in porous media. Experimental evidence and an analysis of pore-scale physics demonstrate conclusively that relative permeabilities are not single functions of fluid saturations and that they display strong hysteresis effects. In this paper, we evaluate the relevance of relative permeability hysteres...

Characterization for Storage of CO2 in Deep Geological Formations

The U.S. Department of Energy (DOE) is the lead Federal agency for the development and deployment of carbon sequestration technologies. As part of its mission to facilitate technology transfer and develop guidelines from lessons learned, DOE is developing a series of best practice manuals (BPMs) for carbon capture and storage (CCS). The ―Site Screening, Site Selection, and Initial Characterizat...

Water‐CO2‐mineral systems: Interfacial tension, contact angle, and diffusion—Implications to CO2 geological storage

[1] The interfacial interaction between mineral surfaces and immiscible fluids determines the efficiency of enhanced oil or gas recovery operations as well as our ability to inject and store CO2 in geological formations. Previous studies have shown that the interfacial tension and contact angle in CO2‐water‐mineral systems change noticeably with fluid pressure. We compile previous results and e...

Stochastic Analysis of Factors Affecting the Leakage of Co2 from Injected Geological Basins
