Automatic Measurement of the Dependence on Pressure and Temperature of the Mass Density of Drilling Fluids
Cayeux, Eric (Peer reviewed; Journal article, 2022)Drilling fluids are subject to substantial variations in pressure and temperature while they are circulated in a well. These changes are so great that the mass density of the drilling fluid varies significantly during ... -
Autonomous Decision-Making While Drilling
Cayeux, Eric; Daireaux, Benoit; Ambrus, Adrian; Mihai, Rodica G.; Carlsen, Liv (Journal article; Peer reviewed, 2021)The drilling process is complex because unexpected situations may occur at any time. Furthermore, the drilling system is extremely long and slender, therefore prone to vibrations and often being dominated by long transient ... -
Calibration of Thixotropic and Viscoelastic Shear-Thinning Fluids Using Pipe Rheometer Measurements
Cayeux, Eric (Peer reviewed; Journal article, 2024)Some non-Newtonian fluids have time-dependent rheological properties like a shear stress that depends on the shear history or a stress overshoot that is a function of the resting time, when fluid movement is started. The ... -
Clock Synchronization and Timestamping of Data on Acquisition at the Wellsite: Guidelines and Recommendations
Annaiyappa, Pradeep; Macpherson, John D.; Cayeux, Eric (Peer reviewed; Journal article, 2023)Due to the nature of drilling operations, there are several companies collecting data at the rig. The data acquisition system of each company applies its own timestamp to the data. Subsequent aggregation of data (for ... -
Connecting Multilayer Semantic Networks to Data Lakes: The Representation of Data Uncertainty and Quality
Cayeux, Eric; Damski, Carlos; Macpherson, John D.; Laing, Moray; Annaiyappa, Pradeep; Harbidge, Philip; Edwards, Michael G.; Carney, Jonathan (Peer reviewed; Journal article, 2022)Drilling oil and gas wells is a complex process involving many disciplines and stakeholders. This process occurs in a context where some pieces of information are unknown, or are often incomplete, erroneous, or at least ... -
Investigation of field scenarios using a 4n degrees of freedom transient torque and drag model
Ambrus, Adrian; Cayeux, Eric; Shor, Roman (Peer reviewed; Journal article, 2023)A coupled drill string dynamics model presents an opportunity to understand, replicate and potentially control the vibrations occurring along a drill string in a deep well. This paper describes a 4n degrees of freedom ... -
Precise Method to Estimate the Herschel-Bulkley Parameters from Pipe Rheometer Measurements
Magnon, Elie; Cayeux, Eric (Journal article; Peer reviewed, 2021)Accurate characterization of the rheological behavior of non-Newtonian fluids is critical in a wide range of industries as it governs process efficiency, safety, and end-product quality. When the rheological behavior of ... -
Self-Attenuation of Drillstring Torsional Vibrations Using Distributed Dampers
Cayeux, Eric; Ambrus, Adrian (Peer reviewed; Journal article, 2023)During drilling operations, drillstring vibrations cause many downhole dysfunctions, resulting in underperformance, equipment failure, and possibly wellbore damage. Current drillstring vibration mitigation solutions are ...
