“…In petroleum exploration and transport, connate water or injected water from enhanced oil recovery operations flows along with oil. Also, in the transport of high viscosity oils, water injection into the annulus of pipelines has been used as a means of reducing friction losses and by extension reducing pumping power requirements [5][6][7][8][9][10][11].…”

Pressure drop and flow pattern of oil–water flows were investigated in a 19-mm ID clear polyvinyl chloride pipe consisting of U-bend with radius of curvature of 100 mm. The range for oil and water superficial velocities tested was $$0.04 \le U_{{{\text{so}}}} \le 0.950 \;{\text{m/s}}$$ 0.04 ≤ U so ≤ 0.950 m/s and $$0.13 \le U_{{{\text{sw}}}} \le 1.10 \;{\text{m/s}}$$ 0.13 ≤ U sw ≤ 1.10 m/s , respectively. Measurements were carried out under different flow conditions in a test section that consisted of four different parts: upstream of the bend, at the bend and at two redeveloping flow locations after the bend. The result indicated that the bend had limited influence on downstream flow patterns. However, the shear forces imposed by the bend caused some shift flow pattern transition and bubble characteristics in the redeveloping flow section after the bend relative to develop flow before the bend. Generally, pressure gradient at all the test sections increased with both oil fraction and water superficial velocity and there was a sharp change of pressure gradient profile during phase inversion. The transition point where phase inversion occurred was always within the range of $$0.4 \le U_{{{\text{sw}}}} \le 0.54 \;{\text{m/s}}$$ 0.4 ≤ U sw ≤ 0.54 m/s . Pressure losses differed at the various test sections, and the difference was strongly linked to the superficial velocity of the phases and the flow pattern. At high mixture velocity, pressure losses at the redeveloping section after the bend were higher than that at the bend and that for fully developed flows. At low mixture velocity, pressure losses at the bend are higher than in the straight sections. Pressure drop generally decreased with level of flow development downstream of the bend.

“…This creates afavorable condition for the cone to occure. Water coning in the wellbore continues to increase with incrasing the pressure drop in the wellbore (Bautista et al, 2014;Pal and Mandal, 2015;Izwan Ismail, 2015a;Desamal et al, 2015;Loh and Premanadhan, 2016). At the optimum fl ow rate of the well, viscous forces are always lower than the gravitational forces, which inhibites the water coning to achive to the wellbore.…”

Oil reservoirs are usually consist of hydrocarbons (oil and gas) and bottom water. The natural depletion of the reservoir occurs by the natural energy of the reservoir. Reservoirs pressures are usually high in the beginning and this will transmit the fl uid from the reservoir to the surface. However, after some time of production, when the reservoir pressure falls down, water comes into the formation and starts to produce through the wellbore. This happens because of the disturbance in gravitational force in the reservoir, which results in water production along with oil. Reducing well productivity, water separation and handling, corrosion and environmental issues are the major challenges associated with water coning phenomena. In this study, the black oil model of ECLIPSE software was used to study the water coning issue in an oil reservoir. Different production plans were studied and their effect on water coning was investigated. In addition, the best production plan was introduced using simulation results. The simulation results showed that pressure draw down in the reservoir decreased with decreasing oil production rate, which inherently decreases the water production rate. Moreover, the simulation results showed that oil recovery factor can be increased signifi cantly by decreasing the amount of water production.

“…The methods of friction reduction include the flow of oil limited by a thin layer of water in the boundary area [4,5] and the use of various additives [6][7][8][9]. Methods of viscosity reduction include heating [10][11][12], ultrasonic treatment [13][14][15][16][17], emulsification of oil in water [18][19][20][21][22], and dilution (mixing with a thinning liquid with lower viscosity, for example, condensate from natural gas extraction, naphtha, kerosene, lighter crude oil, etc.) [23][24][25].…”

One of the methods of influence on rheological properties of heavy high-viscosity crude oils is ultrasonic treatment. Ultrasonic treatment allows reducing the viscosity of crude oil and, therefore, reducing the costs of its production and transportation. In this paper, the influence of ultrasonic treatment on the rheological characteristics of crude oil (sample No. 1 API = 29.1, sample No. 2 API = 15.9) was investigated. An experimental method was developed. Experimental studies were carried out using the Physica MCR 102 rheometer. The influence of the intensity and duration of ultrasonic treatment on the viscosity of the initial crude oils was studied for 24 h. In addition, the rheological characteristics of the treated oil were investigated after its natural cooling to 293 K. The results are compared with similar results for thermal heating.
