Application of the quemada viscosity model for drilling fluids
Knutsen, Sandra; Cayeux, Eric; Saasen, Arild; Khalifeh, Mahmoud (Chapter, 2021)A number of different models are used to describe the shear rate dependent viscosity of drilling fluids. Most, such as the Herschel-Bulkley model, have a purely empirical basis. The Quemada model, while still empirical, ... -
Flow-Rate Out Measurement from a Well During Drilling
Wirgenes, Trym (Masteroppgave/UIS-TN-IPT/2017;, Master thesis, 2017-06)Accurate measurements of flow rate out is crucial in order to prevent unnecessary harm to the environment, equipment or personnel. Harmful situations, such as inflows can potentially be detected earlier with a precise ... -
Mathematical Modelling of the Drilling Process for Real-time Applications in Drilling Simulation, Interpretation and Assistance
Cayeux, Eric (PhD thesis UiS;, no.;506, Doctoral thesis, 2019)For the last thirty years, mathematical modelling has been used to develop software solutions that support drilling engineering activities at the planning stage of drilling operations. But it is only for the last decade ... -
Multi-framework numerical model of the interaction between drilling fluid and drill-string
Volpi, Lucas Passos (PhD thesis UiS;836, Doctoral thesis, 2025)The need for drilling in deeper depths and different conditions drives the development of technologies associated with geoenergy sources. This process is defined by a tighly woven multi-physics environment where there is ... -
Whirling dynamics of a drill-string with fluid–structure interaction
Volpi, Lucas; Cayeux, Eric; Time, Rune Wiggo (Peer reviewed; Journal article, 2023)Fluid–structure interaction models for drill-string vibrations are often of reduced order. However, both the structure and the surrounding fluid are non-linear, which can lead to complex coupled dynamic. In this paper, a ...
