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 ... -
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. ... -
Experimental Study of the use of Particles for Tracking the Interfaces in Primary Cementing of Concentric and Eccentric Wells
Taheri, Amir; Ytrehus, Jan David; Taghipour, Ali; Lund, Bjørnar; Lavrov, Alexandre; Torsæter, Malin (SINTEF Proceedings;4, Chapter; Conference object; Peer reviewed, 2019)In this study, our recent and new approach for detailed tracking of the interface between well fluid and cement by using particles is investigated. The particles can enable us to know the precise location of the interface ... -
Experimental study of the use of tracing particles for interface tracking in primary cementing in an eccentric hele–shaw cell
Taheri, Amir; Ytrehus, Jan David; Lund, Bjørnar; Torsæter, Malin (Peer reviewed; Journal article, 2021)We present the results of the displacement flows of different Newtonian and Herschel–Bulkley non-Newtonian fluids in a new-developed eccentric Hele–Shaw cell with dynamic similarly to real field wellbore annulus during ... -
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 ... -
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 ...
