Reduced metal loss to slag in HC FeCr production - by redesign based on mathematical modelling
Rheological characterization of Polyanionic Cellulose solutions with application to drilling fluids and cuttings transport modeling
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 transportation of drilled-off solids out of the wellbore. In these studies, PAC ...
Cuttings-transport modeling-part 1: Specification of benchmark parameters with a norwegian-continental-shelf perspective
In oil and gas drilling, cuttings transport related problems are a major contributor to well downtime and costs. As a result, solutions to these problems have been extensively researched over the years, both experimentally and through simulation. Numerous review articles exist, summarizing not only ...
Development of an advanced imaging technique for dynamic emulsion stability
SOFT: A FRAMEWORK FOR SEMANTIC INTEROPERABILITY OF SCIENTIFIC SOFTWARE
In this paper we present our strategy and implementation of a datacentric modelling framework (SOFT, SINTEF Open Framework and Tools) with focus on information interchange in throughprocess and multiscale applications. SOFT needs to accommodate for a inhomogeneous set of in-house open source and pro...
A CARTESIAN CUT-CELL METHOD, BASED ON FORMAL VOLUME AVERAGING OF MASS, MOMENTUM EQUATIONS
A SIMULATION CONCEPT FOR GENERIC SIMULATION OF MULTI-MATERIAL FLOW USING STAGGERED CARTESIAN GRIDS
CFD MODELING OF DYNAMIC EMULSION STABILITY
On pragmatism in industrial modeling. Part III: Application to operational drilling
In this paper, we will apply the concepts of pragmatic industrial modelling to the development of a real time drilling support tool. We develop requirements to such a modelling tool, regarding both input and output, model response times, and accuracy requirement. The selected application will next b...
