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 especially in geothermal wells.This study experimentally investigated the effect of temperature on friction pressure loss through vertical concentric annulus by usingwater and the polymer based drilling fluid including Polyanionic Cellulose and Xanthan Gum. Experiments were conducted in flow loophaving 21-ft smooth and concentric annular test section (2.91 in ID casing x 1.85 in OD pipe).The effect of temperature on rheological model parameters, apparent viscosity, Reynolds number was examined. It was found thatconsistency index and yield point were more sensitive to change in temperature than flow behavior index. Also, apparent viscositydecreased exponentially with increasing temperature and this decrease was more obvious in low shear rate values. Then, according toReynolds number – temperature plot, earlier regime transition was observed with increasing temperature.As a result, increasing temperature caused the decrease in friction pressure loss, and temperature effect should be considered in futureexperimental and theoretical studies in order to estimate friction pressure loss in annuli precisely.


Experimental investigation of the effect of temperature on friction pressure loss of polymeric drilling fluid through vertical concentric annulus

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...
Experimental characterization of some water soluble polymers used in drilling and completion fluids
Gürbüz, Berkay; Mehmetoğlu, Mustafa Tanju; Department of Petroleum and Natural Gas Engineering (2012)
Properly preparing the drilling fluid is an essential part of any successful drilling operation, especially in complex operations like deviated and horizontal drilling. Understanding the flow behavior of the polymers used in the drilling fluids under different conditions takes a key part in this preparation. In this study, shear rheology of some traditionally used water soluble polymers in drilling and completion fluids; namely PAC (polyanionic cellulose) and xanthan gum, were investigated experimentally. I...

SORGUN, Mehmet; Ozbayoglu, M. Evren; Aydın, İsmail (2010-09-01)
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 dynamic...
Experimental investigation of solids transport in horizontal concentric annuli using water and drag reducing polymer-based fluids
Allahvirdizadeh, Payam; Kuru, Ergun; Parlaktuna, Mahmut (2016-09-01)
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 experie...
Investigation of bit hydraulics for gasified drilling fluids
Doğan, Hüseyin Ali; Özbayoğlu, Mehmet Evren; Department of Petroleum and Natural Gas Engineering (2004)
Accurate determination of the pressure losses at the bit is very important for drilling practices in petroleum industry. In the literature, there are several studies on determination of the pressure losses. Major focus is concentrated on single phase drilling fluids, which is far from accurate estimation of pressure losses for multiphase fluids, i.e., fluids including a liquid and a gas phase, at the bit. Some of these models are valid for multiphase fluids, however, they are either valid for very high gas ...
