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 ... -
Characterization of Annular Cement Permeability of a Logged Well Section Using Pressure-Pulse Decay Measurements
Skadsem, Hans Joakim (Peer reviewed; Journal article, 2022)The cement behind casings is an important barrier element in wells that should provide zonal isolation along the well. The hardened cement does not always isolate permeable formations, either due to placement issues or ... -
Computational fluid dynamics simulation of buoyant mixing of miscible fluids in a tilted tube
Ghorbani, Maryam; Giljarhus, Knut Erik Teigen; Skadsem, Hans Joakim; Time, Rune Wiggo (Peer reviewed; Journal article, 2021)Buoyancy-driven flows and mixing of fluids with different densities occur frequently both in nature and as part of industrial processes within chemical and petroleum engineering. This work investigates the buoyant exchange ... -
Concentric cylinder viscometer flows of Herschel-Bulkley fluids
Skadsem, Hans Joakim; Saasen, Arild (Peer reviewed; Journal article, 2019)Drilling fluids and well cements are example non-Newtonian fluids that are used for geothermal and petroleum well construction. Measurement of the non-Newtonian fluid viscosities are normally performed using a concentric ... -
Development of a novel experimental technique for the measurement of residual wall layer thickness in water-oil displacement flows
Zhang, Yao; Barrouillet, Benjamin; Chavan, Sachin Maruti; Skadsem, Hans Joakim (Peer reviewed; Journal article, 2023)The effective removal and displacement of fluids is important in many industrial and environmental applications, such as for operation and cleaning of process equipment, fluid injection in porous media for oil recovery or ... -
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, 2020-09)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 ... -
The effect of PVA microfiber reinforcement on the mechanical and rheological behavior of class G oil well cement pastes
Nogueira Lima, Victor; Skadsem, Hans Joakim; Beltrán-Jiménez, Katherine; Velloso, Raquel Quadros; Silva, Flávio de Andrade (Peer reviewed; Journal article, 2023)During the life cycle of an oil well, the annular cement sheath will be exposed to load combinations that can result in failure. To enhance the structural integrity and ductility of the cement paste, and to improve the ... -
Effects of confinement pressure on the mechanical behavior of an oil well cement paste
Lima, Victor Nogueira; Silva, Flavio de Andrade; Skadsem, Hans Joakim; Beltran Jimenez, Katherine; Sunde, Jonas Kristoffer (Peer reviewed; Journal article, 2021-11)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 ... -
Experimental investigation of laminar and turbulent displacement of residual oil film
Zhang, Yaozhi; Barrouillet, Benjamin; Skadsem, Hans Joakim (Peer reviewed; Journal article, 2023-11)Residual oil films on pipe walls are a common occurrence in industrial processes, and their presence can significantly impact system efficiency and performance. However, the mechanisms that govern oil film removal by an ... -
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 ... -
Influence of fluid viscosity hierarchy on the reverse-circulation displacement efficiency
Ghorbani, Maryam; Giljarhus, Knut Erik Teigen; Skadsem, Hans Joakim (Peer reviewed; Journal article, 2023)Reverse-circulation cementing is an alternative strategy for well cementing where the cementing fluids are injected directly into the annulus from the surface. This cementing strategy can reduce downhole circulation pressures ... -
Interfacial Dynamics of Miscible Displacement of Shear-Thinning Fluid in a Vertical Channel
Zhang, Yao; Rabenjafimanantsoa, Andrianifaliana Herimonja; Skadsem, Hans Joakim (Peer reviewed; Journal article, 2023)Abstract The displacement of a shear-thinning fluid by a denser and less viscous Newtonian fluid in a vertical duct is investigated using experiments and numerical simulations. We study how shear-thinning and increased ... -
A numerical study of density-unstable reverse circulation displacement for primary cementing
Skadsem, Hans Joakim; Kragset, Steinar (Peer reviewed; Journal article, 2022)Primary cementing of the casing string is the operation where the annular space behind the casing is displaced to a cement slurry. Once hardened, the cement should form a solid annular barrier and provide zonal isolation ... -
