RISEffect of Near-Wall Turbulence on Selective Removal of Particles From Sand Beds Deposited in Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper investigates the effect of near-wall turbulence on selective removal of small-size particulate matter from sand beds deposited in pipelines. In an effort to develop effective strategies ...
Selective Removal of Particles and Shifting of Particle-Size Distribution during Pipeline Transport of Sediment Deposits under Turbulent Flow
Publisher: American Society of Civil Engineers
Occurrence of Naturally Shaped Lenticular Bed Deposit and Its Influence on the Frictional Pressure Drop during Pipeline Transportation of Low Concentration Slurries
Publisher: American Society of Civil Engineers
Abstract: Solid particles can be transported along a pipeline in the form of trains of individually shaped lenticular deposits (LDs) when the concentration of solids is less than 1 vol% and the transport velocity is below the critical ...
The Buckling Behavior of Pipes and Its Influence on the Axial Force Transfer in Directional Wells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental setup was built at the University of Tulsa to study buckling and post-buckling behavior of pipes constrained in straight horizontal and curved wellbores. Experiments were conducted ...
Experimental Evaluation of the Lateral Contact Force in Horizontal Wells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In horizontal and extended reach drilling, a large frictional drag may occur. If the pipe buckles laterally or into a helical shape, additional lateral contact force, LCF, is developed between ...
Rheological Properties of Clay-Based Drilling Fluids and Evaluation of Their Hole-Cleaning Performances in Horizontal Directional Drilling
Publisher: ASCE
Abstract: Hole cleaning is a significant issue in well drilling, and this problem becomes more severe in horizontal directional drilling (HDD). One of the main functions of the drilling fluid is to transport cuttings from the borehole ...
