When drilling long horizontal wells, drilled solids tend to settle down on the low side of the welibore and form a stationary bed. Presence of stationary cuttings bed causes operational difficulties such as pack-off, excessive torque and drag, slow drilling rate, and in severe cases, stuck pipe, lost circulation, and even loss of the well control. Despite significant progress made in drilling fluids, tools, and field practices, along with more than 50 years of university and industry research, field experience indicates that cuttings transport is still a major problem in most horizontal wells.

A Comparative study of cuttings transport performance of water versus polymer-based fluids in horizontal well drilling Allahvirdizadeh, Payam; Parlaktuna, Mahmut; Kuru, Ergun; Department of Petroleum and Natural Gas Engineering (2015) High drilling fluid circulation rate is often needed for effective transportation of cuttings in horizontal and extended reach wells, which may not be always achievable due to the risk of fracturing the rock by increased bottom hole dynamic pressure and also limit of pumps capacity. Keeping the bottom hole pressure low enough while increasing the flow rate is, therefore, a major challenge in horizontal well drilling operations. A potential solution to this problem would be to use drag reducing additives in ...
Experimental Investigation of the Effect of Temperature on Friction Pressure Loss of Polymeric Drilling Fluid Through Vertical Concentric Annulus Gürçay, Kazım Onur; Akın, Serhat; Gucuyener, Hakkı (null; 2019-02-14) Accurate estimation of annular friction pressure loss is necessary to perform drilling and well completion operations without lostcirculation, pipe sticking or more serious well control problems. Determination of friction pressure loss for Newtonian and non-Newtonianfluids has been investigated in several experimental and theoretical works by considering the effects of eccentricity, pipe rotation or pipegeometry. However, there is a gap in the studies about the temperature effect that is important especiall...
Application of artificial neural networks to predict the downhole inclination in directionally drilled geothermal wells Burak, Tunç; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2018) Drilling directionally through naturally fractured geothermal reservoirs is a challenging task due to unexpected changes in inclination and azimuth of the well axis, which causes inefficient weight on bit transfer, decrease in penetration rate, increasing the risk of stuck pipe and problems in while running casings. To predict the sudden changes in inclination while drilling, a back propagation, feed forwarded multi layered artificial neural network (ANN) model, which uses drilling data collected from 12 J-...
Experimental investigation of the effect of temperature on friction pressure loss of polymeric drilling fluid through vertical concentric annulus Gürçay, Kazım Onur; Akın, Serhat; Gücüyener, İsmail Hakkı; Department of Petroleum and Natural Gas Engineering (2018) Accurate estimation of friction pressure loss through annulus is important to avoid lost circulation, pipe sticking, kicks or more serious problems in drilling and well completion operations. Several studies have been performed to determine friction pressure loss experimentally and theoretically through pipe and annulus with the effects of eccentricity, pipe rotation, annulus geometry or flow regime by applying several rheological models. However, in addition to all of these factors, fluid rheology is depen...
Nanoscale active tuning of the second harmonic generation efficiency in semiconductors from super-low to gigantic values Asirim, Ozum Emre; Kuzuoğlu, Mustafa (2022-08-01) Second harmonic generation efficiency (SHGE) strongly depends on the length of the interaction material along the beam propagation axis. Since a nanoscale interaction length is considered too short even in the optical wavelength scale, the attained SHGE through nanomaterials is usually too low to be of practical use. In this study, it will be shown that by properly adjusting the conduction-band electron density in a semiconductor nanomaterial under a certain optical pumping rate (active tuning), the SHGE ca...
