A major concern in drilling operations is the proper determination of frictional pressure loss in order to select a mud pump and avoid any serious problems. In this study, a mechanistic model is proposed for predicting the frictional pressure losses of light drilling fluid, which can be used for concentric annuli. The experimental data that were available in the literature and conducted at the Middle East Technical University-Petroleum Engineering (METU-PETE) flow loop as well as computational fluid dynamics (CFD) software are used to verify the results from the proposed mechanistic model. The results showed that the proposed model can estimate frictional pressure losses within a +/- 10% error interval when compared with the experimental data. Additionally, the effect of the pipe eccentricity on frictional pressure loss and tangential velocity using CFD for laminar and turbulent flow is also examined. It has been observed that pipe eccentricity drastically increases the tangential velocity inside the annulus; especially, the flow regime is turbulent and frictional pressure loss decreases as the pipe eccentricity increases.

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...
Numerical modeling of counter-current spontaneous imbibition during underbalanced drilling
Naseri, Masoud; Sınayuç, Çağlar (2012-09-10)
Mud solid and filtrate invasion are the most common causes of formation damage during overbalanced drilling (OBD), which is a method of drilling in which the wellbore pressure remains greater than formation pressure. During the past ten years, underbalanced drilling operations (UBD), which can be defined as a drilling method in which the wellbore pressure is less than formation pressure, has been growing due to their applications such as prevention of lost circulation, reduction of filtration lost in natura...
performance analysis of drilling fluid liquid lubricants
Sönmez, Ahmet; Kök, Mustafa Verşan; Department of Petroleum and Natural Gas Engineering (2011)
Excessive torque is one of the most important problems in oil/gas drilling industry. Friction between wellbore/casing and drill string causes excessive torque. This study discusses performance analysis of drilling fluid lubricants, which are used as friction reducers in well-bore. Three different types of commercial chemical lubricants, which are fatty acid and glycerid based, triglycerid and vegetable oil based and polypropylene glycol based, diesel oil, and crude oil, which consists of different API gravi...
DESIGN AND MODELLING OF A HYBRID PRESSURE REGULATOR
Gürfidan, Mehmet Gökalp; Yazıcıoğlu, Yiğit; Department of Mechanical Engineering (2022-9-14)
Pressure regulator is used for regulating high upstream pressure to required low downstream pressure. It is especially an important component for space applications where an accurate pressure control is vital, and failure to do so can cause mission failure. In this thesis a novel pressure regulator design is modeled that eliminates the inherent steady state error of purely mechanical pressure regulator by introducing cascaded electromechanical actuator. Dynamic components of the proposed hybrid pressure reg...
Numerical investigation of hydraulic characteristics of Laleli Dam spillway and comparison with physical model study
Usta, Eray; Köken, Mete; Department of Civil Engineering (2014)
Spillway is a hydraulic structure that is used to pass big discharges in flood times in a controlled manner and release surplus water that cannot be safely stored in the reservoir to downstream. During the design process of the spillways, determining of hydraulic behavior of these structures is a very significant issue for an accurate and optimum design. In this thesis, the objective is to investigate the hydraulic characteristics of the flow over Laleli dam spillway numerically and compare the results with...
