Cement properties characterization from a section retrieved from an oil production well after 33 years of downhole exposure
Beltran Jimenez, Katherine; Gardner, Dave; Kragset, Steinar; Gebremariam, Kidane Fanta; Reales, Oscar A. M.; Minde, Mona Wetrhus; Lourenco de Souza, Marcelo I.; Aasen, Jan Aage; Skadsem, Hans Joakim; Delabroy, Laurent (Peer reviewed; Journal article, 2021)A unique data set has been constructed based on the study of class G cement recovered from an oil well on the Norwegian continental shelf. The cement was placed between two casing sections and submitted to downhole conditions ... -
Effect of buoyancy and inertia on viscoplastic fluid-fluid displacements in a regular and an irregular eccentric annulus
Skadsem, Hans Joakim; Kragset, Steinar (Peer reviewed; Journal article, 2020)Casing strings and liners are important subsurface structural components in petroleum and in geothermal wells. After the casing string has been run in hole, it is cemented to the formation by pumping a sequence of spacer ... -
Effects of confinement pressure on the mechanical behavior of an oil well cement paste
Lima, Victor Nogueira; Silva, Flávio de Andrade; Skadsem, Hans Joakim; Beltrán-Jiménez, Katherine; Sunde, Jonas Kristoffer (Peer reviewed; Journal article, 2021)Oil well cement paste is a key structural component in wells that should provide mechanical support to the casing and prevent uncontrolled flow of formation fluids along the wellbore and to the environment. Since the annular ... -
Fluid Migration Characterization of Full-scale Annulus Cement Sections Using Pressure-Pulse-Decay Measurements
Skadsem, Hans Joakim (Peer reviewed; Journal article, 2021)Fluid migration behind casings is a well integrity problem that can result in sustained casing pressure, undetected leaks to the environment, and potentially very challenging remediation attempts. Understanding the geometric ... -
Pipe Viscometer for Continuous Viscosity and Density Measurement of Oil Well Barrier Materials
Nogueira Lima, Victor; Randeberg, Erlend; Taheri, Amir; Skadsem, Hans Joakim (Peer reviewed; Journal article, 2023)The barrier material is a crucial component for wells, as it provides mechanical support to the casing and prevents the uncontrolled flow of formation fluids, ensuring zonal isolation. One of the essential prerequisites ... -
Restoration of annular zonal isolation using localized casing expansion (LCE) technology: Treatment of near-horizontal test sections containing a free-water channel
Beltran Jimenez, Katherine; Skadsem, Hans Joakim; Sunde, Jonas Kristoffer; Gardner, Dave; Wolterbeek, Timotheus K T; Cornelissen, Erik; Keultjes, Wout J. G. (Journal article; Peer reviewed, 2021)Fluid migration behind casings is a well integrity problem that can result in sustained casing pressure, undetected leaks to the environment, and potentially very difficult remediation attempts. Traditional methods for ... -
Triaxial behavior of a stabilized and a highly porous oil well cement paste at different saturation and drainage conditions
Lima, Victor Nogueira; Skadsem, Hans Joakim; Beltrán-Jiménez, Katherine; Zhemchuzhnikov, Alexandr; Velloso, Raquel Quadros; Silva, Flavio de Andrade (Peer reviewed; Journal article, 2022)Well cement is the most common barrier material in wells for geothermal and hydrocarbon production. As cements are exposed to hydrostatic loads and periods of deviatoric loading in wellbore environments, it is important ... -
Vibration-assisted annular fluid displacement for rig-less well abandonment operations
Skadsem, Hans Joakim; Giljarhus, Knut Erik Teigen; Øijordsbakken Fredheim, Fiona; van Riet, Egbert; Keultjes, Wout J. G. (Journal article; Peer reviewed, 2022)Through-tubing abandonment is the operation where the production tubing is cut or punched and cemented inside the production casing. This can establish a full cross-sectional barrier or isolation in wells where the cement ...
