Experimental investigation of the high-pressure sealing capacity for three different LCM systems
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)As loss of circulation is still a major problem in the drilling industry, hundreds of lost circulation treatments are available on the market. The goal of this thesis is not to present a complete list of available products, ... -
Experimental Study of Automated Characterization of Non-Newtonian Fluids
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-08)The automation of the drilling fluid properties measurement is a research area that has been pursued in the last few years by the oil industry. Adequate control and monitoring of the density and rheology of the drilling ... -
Experimental study on thermal effects on well components
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06)The main objective of inflow control devices is to maintain a uniform inflow by providing an additional pressure loss between the formation and the wellbore. ICDs delay the production of water or gas, and thus increase the ... -
Input Selection for Dimensionless Shear Rates in Herschel-Bulkley and Power-Law Models
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)Herschel-Bulkley and Power-Law models are mathematical expressions widely used to describe the pseudoplastic nature of drilling muds. Despite their popularity, these models carry an intrinsic limitation because the consistency ... -
