A Study of the Ultrasonic Measurements for Logging Behind a Steel Pipe: Expanding the proessing to improve the differentiation between heavy fluids and light solids
Sirevaag, Tore Lie (Doctoral theses at NTNU;2019:375, Doctoral thesis, 2020)In petroleum applications using acoustic wave theory, the most used practice can be found in borehole geophysical methods, where acoustic logging has long been the foremost source for cement evaluation. Due to stricter ... -
Elastic to Non-Elastic Rock Deformation Studied by Combination of Static and Dynamic Measurements - Investigating the Behaviour of the Non-Elastic Response
Sirevaag, Tore Lie (Master thesis, 2016)Tidligere studier gjort på ren sandstein under reduksjon av spenning fra et vendepunkt, viser en lineær tendens for den ikke-elastiske inverse stivheten. Ved å anvende denne lineære oppførselen til steinen kan man ekstrapolere ... -
Non-elastic effects in static and dynamic rock stiffness
Lozovyi, Serhii; Sirevaag, Tore Lie; Szewczyk, Dawid; Bauer, Andreas Kurt Marcel; Fjær, Erling (Chapter, 2017)The static stiffness of a rock is generally smaller than its dynamic stiffness, which, for non-dispersive rocks, is due to a difference in strain amplitude in compaction tests (quasi-static) and wave-velocity measurements ...
