Comparison of Sealing Properties of Amundsen and Drake Formations for Potential CO2 Storage in North Sea
Fawad, Manzar; Mondol, Nazmul Haque (Chapter, 2019)Seal evaluation for CO2 storage is different from that of a hydrocarbon trap since the oil or gas accumulation itself validates the cap-rock integrity. However, in case of subsurface CO2 storage a careful investigation is ... -
Effect of brine-CO2 fracture flow on velocity and electrical resistivity of naturally fractured tight sandstones
Nooraiepour, Mohammad; Bohloli, Bahman; Park, Joonsang; Sauvin, Guillaume; Skurtveit, Elin; Mondol, Nazmul Haque (Peer reviewed; Journal article, 2017)Fracture networks inside geological CO2 storage reservoirs can serve as primary fluid flow conduit, particularly in low-permeability formations. While some experiments focused on the geophysical properties of brine- and ... -

Kalani, Mohsen; Zadeh, Mohammad Koochak; Jahren, Jens; Mondol, Nazmul Haque; Faleide, Jan Inge (Journal article, 2015)Pore pressure in fine-grained rocks is important with respect to drilling problems such as kicks, blowouts, borehole instability, stuck pipe and lost circulation. In this study, a succession of overpressured, fine-grained, ... -
Effects of stress reduction on geomechanical and acoustic relationship of overconsolidated sands
