A decision support system for multi-target geosteering
(Journal article; Peer reviewed, 2019-12)Geosteering is a sequential decision process under uncertainty. The goal of geosteering is to maximize the expected value of the well, which should be defined by an objective value-function for each operation. In this paper ... -
Application of the quemada viscosity model for drilling fluids
(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, ... -
The effect of PVA microfiber reinforcement on the mechanical and rheological behavior of class G oil well cement pastes
(Peer reviewed; Journal article, 2023)During the life cycle of an oil well, the annular cement sheath will be exposed to load combinations that can result in failure. To enhance the structural integrity and ductility of the cement paste, and to improve the ... -
Experimental Methods for Investigation of Drilling Fluid Displacement in Irregular Annuli
(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. ... -
Rheological characterization of Polyanionic Cellulose solutions with application to drilling fluids and cuttings transport modeling
(Peer reviewed; Journal article, 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 ...
