A Study of the Effect of Pressure and Temperature on the Mechanical Friction of Four Different Fluids Using a Specially Designed Setup
Ghaedi, Parisa (Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)The mechanical friction caused by the contact between the rotating drillstring and the borehole or casing can lead to significant challenges such as excessive torque and drag, limitation in running speed of drillstring and ... -
Barite Sag Settling measurement techniques – direct method
Rezaei, Milad (Master thesis, 2021)One of the main roles of drilling fluid is controlling the downhole pressure. Weighting materials are employed in drilling fluid for this aim. Barite is the most common agent, which is used for increasing density. There ... -
Development and Characterization of a Pressure Transmitting Sag Prevention Gel Pill
Penkala, Larisa Sonja (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-06-08)Barite sag is a risky phenomenon to manage as particle settlement occurs in all types of drilling fluids containing weighting agents’ materials to achieve density. This leads to the phenomenon of sag which is known to ... -
Input Selection for Dimensionless Shear Rates in Herschel-Bulkley and Power-Law Models
Brasileiro, Raoni (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 ... -
Measuring the Magnetic Content of Drilling Fluid
Khalili, Pouya (Master thesis, 2021)Magnetic contamination of drilling fluid can impact the accuracy of the directional surveying by shielding the magnetic field. Additionally, this contamination, such as swarf or finer magnetic particles, can agglomerate ... -
New method for measuring viscosity of mixtures of two fluids
Slettebø, Jon Kristian (Bachelor thesis, 2023)When executing a drilling operation in a well, rheological properties are important to understand in order to have the most error- and problem-free drilling operation as possible. Drilling fluids such as mud, spacer and ... -
Optimizing formulations for reservoir drilling fluids
Bergsvik, Ine Skartveit (Bachelor thesis, 2022)When drilling a well, equivalent circulation density exceeding the fracture gradient can cause lost circulation. In a reservoir section, invasion of drilling fluids can potentially cause a permanent permeability reduction ... -
Recent developments in hole cleaning technology in deviated well bores for geothermal and petroleum
Gåseland Bekkevik,Sindre (Bachelor thesis, 2022)This paper is looking on recent developments in hole cleaning technologies and how recent advancements can be used to aid efficient hole cleaning in deviated wells. Successful hole cleaning relies upon integrating optimum ... -
Use of the Quemada Model for Modelling Viscous Behaviour of Drilling Fluids.
Knutsen, Sandra (Masteroppgave/UIS-TN-IEP/2020;, Master thesis, 2020-07-15)Drilling fluids are essential for drilling operations and serve many important functions. To maintain control of the wellbore, while ensuring sufficient cutting transportation, good understanding of the rheological properties ... -
Using ceramic discs to evaluate fluid loss and formation damage
Trodal, Vegard (Bachelor thesis, 2021)To prevent kicks and possible blowout of the well, the pressure from the drilling fluid must be kept above the pore pressure of the formation. This differential pressure forces the fluid into the porous formation, which ...
