A 2D sediment bed morphodynamics model for turbulent, non-Newtonian, particle-loaded flows
Busch, Alexander; Khatibi, Milad; Johansen, Stein Tore; Time, Rune Wiggo (Chapter, 2017)In petroleum drilling, cuttings transport problems, i.e. an accumulation of drilled of solids in the wellbore, are a major contributor to well downtime and have therefore been extensively researched over the years, both ... -
Cuttings transport: On the effect of drill pipe rotation and lateral motion on the cuttings bed
Busch, Alexander; Johansen, Stein Tore (Peer reviewed; Journal article, 2020)Drill pipe rotation is considered a relevant factor for cuttings transport and hole cleaning. However, in the term “rotation” is often used as a moniker for the combination of plain drill pipe rotation around its own axis ... -
On the validity of the two-fluid-KTGF approach for dense gravity-driven granular flows as implemented in ANSYS Fluent R17.2
Busch, Alexander; Johansen, Stein Tore (Peer reviewed; Journal article, 2020)( Engelsk ) As a subproblem of solid transport in wellbores, we have investigated the cliff collapse problem by means of the Two-Fluid-Model (TFM), where the rheological description of the second phase (sand) is governed ... -
Rheological characterization of Polyanionic Cellulose solutions with application to drilling fluids and cuttings transport modeling
Busch, Alexander; Myrseth, Velaug; Khatibi, Milad; Skjetne, Paal; Hovda, Sigve; Johansen, Stein Tore (Journal article; Peer reviewed, 2018)In petroleum drilling, aqueous Polyanionic Cellulose solutions (PAC) are often used as a drilling fluid model system in experimental laboratory studies to investigate cuttings transport. Cuttings transport refers to the ...
