Annular frictional pressure losses for drilling fluids
Saasen, Arild; Ytrehus, Jan David; Lund, Bjørnar (Peer reviewed; Journal article, 2020)In the paper it is demonstrated how a Herschel-Bulkley fluid model, where the parameters are selected from relevant shear rate range of the flow and are parametrically independent, can be used for pressure loss calculations. ... -
Cement Placement: An Overview of Fluid Displacement Techniques and Modelling
Foroushan, Hanieh K.; Lund, Bjørnar; Ytrehus, Jan David; Saasen, Arild (Peer reviewed; Journal article, 2021)During drilling operations, effective displacement of fluids can provide high-quality cementing jobs, ensuring zonal isolation and strong bonding of cement with casing and formation. Poor cement placements due to incomplete ... -
Cuttings Transport With Oil- and Water-Based Drilling Fluids
Ytrehus, Jan David; Lund, Bjørnar; Taghipour, Ali; Saasen, Arild (Peer reviewed; Journal article, 2023)Deviated well sections are common in most modern offshore well construction designs. In the North Sea region, which is a good example of mature areas, practically all producer or injector wells have highly deviated well ... -
Experimental Bench-Scale Study on Cuttings-Bed Erosion in Horizontal Wells
Pedrosa Consicion, Herman Camilo; Lund, Bjørnar; Opedal, Nils van der Tuuk; Ytrehus, Jan David; Saasen, Arild (Peer reviewed; Journal article, 2022)Cuttings-beds formation while drilling wellbores is a common challenge, especially for horizontal wells, as drilled particles have higher area to be deposited and form cuttings-beds, which can cause several problems such ... -
Experimental Methods for Investigation of Drilling Fluid Displacement in Irregular Annuli
Lund, Bjørnar; Taghipour, Ali; Ytrehus, Jan David; Saasen, Arild (Peer reviewed; Journal article, 2020)Experimental methods are still indispensable for fluid mechanics research, despite advancements in the modelling and computer simulation field. Experimental data are vital for validating simulations of complex flow systems. ... -
Fundamentals and physical principles for drilled cuttings transport – Cuttings bed sedimentation and erosion
Pedrosa, Camilo; Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2021)The increasing necessity of challenging wellbore structures and drilling optimization for improved hole cuttings cleaning has been growing along time. As a result, operator companies have been researching and applying ... -
Hole cleaning and wet-granular rheology of rock cutting beds: Impact of drilling fluid composition
Pedrosa, Camilo; Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2022)Cuttings-beds formation is an issue that must be considered during all wellbore drilling operations. This problem increases at highly deviated or horizontal wells, where cuttings removal efficiency becomes one of the most ... -
Rheology assessment and barite sag in a typical North Sea oil-based drilling fluid at HPHT conditions
Ofei, Titus Ntow; Ngouamba, Elie; Opedal, Nils van der Tuuk; Lund, Bjørnar; Saasen, Arild (Peer reviewed; Journal article, 2023)The occurrence of barite sag in drilling fluids has relatively often been the cause for gas kicks in oilwell drilling. The subsequent absorption of gas into drilling fluid could lower the density and reduce the viscosity ... -
Viscosity Models for Drilling Fluids: Herschel-Bulkley Parameters and Their Use
Saasen, Arild; Ytrehus, Jan David (Peer reviewed; Journal article, 2020)An evaluation is presented of the practical usage of the Herschel-Bulkley viscosity model for drilling fluids. If data from automatic viscosity measurements exist, the parameters should be selected from relevant shear rate ... -
Wet Drilled Cuttings Bed Rheology
Pedrosa, Camilo; Saasen, Arild; Lund, Bjørnar; Ytrehus, Jan David (Peer reviewed; Journal article, 2021)The cuttings transport efficiency of various drilling fluids has been studied in several approaches. This is an important aspect, since hole cleaning is often a bottleneck in well construction. The studies so far have ...
