摘要： There is disclosed a method of separating a mixture (e.g. dispersion) of oil and water into oil-rich and water-rich phases, the method comprising the steps: (i) selecting a mixture which comprises oil recovered from a subterranean formation and a treatment formulation, wherein said treatment formulation was added to the oil in order to facilitate its recovery and/or mobility, wherein said treatment formulation has an Interfacial Tension (IFT), measured against a sample of said oil in the range 2 to 20 mN/m; (ii) directing said mixture to a separation means; and (iii) in the absence of a chemical demulsifier, heating the mixture until separation is effected at least partially under gravity. Preferably the IFT is in the range 9 to 12 mN/m. The mixture of oil and water may be formed by treating oil in a subterranean formation.

摘要： An oil production arrangement comprises an oil reservoir (4), a horizontal wellbore (6) and a vertically extending production well (8). A pump (10) is positioned at the bottom of the production well (8) for pumping fluid along the horizontal wellbore and up the production well for recovery. Tubing (12) having a fluid delivery device (14) at its end is introduced into the production well and moved downwards past the pump (10) and along the horizontal wellbore as far as possible for example close to the toe (not shown) of the wellbore or at least beyond a point in the wellbore at which it is assessed that the hydrocarbon flow has terminated because of a balance between reservoir pressure and wellbore differential pressure being achieved. From the start (or for example as soon as the tubing (12) enters the vertical annular gap between the product well and production tube) of introduction of tubing (12) into the production well and continuously thereafter a fluid is pumped through the tubing so it passes into the production well (8) as the tubing passes therethrough and into the horizontal wellbore (6) as the tubing passes therethrough. The fluid is still pumped into the horizontal wellbore after the tubing has reached its final position deep in the wellbore. The fluid is selected to enhance the mobility of oil and therefore increase the oil production rate.

摘要： An oil well includes a wellbore (2), below ground level (4), which extends to an oil reservoir (6). The wellbore includes a casing (8) within which is arranged a progressing cavity pump (PCP) 10 which includes an inlet (12) at its lower end and is connected at its upper end to production tube (14). An annulus (16) is defined between the pump (10)/tube (14) and the casing (8). The annulus communicates with the reservoir and includes a head (20) of reservoir fluid. A water based formulation which comprises an optionally cross-linked polyvinylalcohol can be poured down the annulus (16) and pass under gravity to the reservoir (6), immediately upstream of inlet (12). The formulation may improve the performance and efficiency of the pump (10) due to its ability to increase the mobility of the oil in the reservoir immediately upstream of the pump (10) and/or enhance the ability of the oil to enter the pump inlet. Furthermore, by improving mobility and/or reducing the level of back pressure when the oil enters the pump inlet (or any other constriction) the rate of flow of oil from the reservoir into the wellbore may be increased resulting in an increased rate of oil production.

摘要： A viscous fluid, such as heavy crude oil which is too viscous to enable it to be pumped from a flowing phase of a reservoir into and along a pipeline for delivery to a refinery or other storage facility, may be contacted with a formulation to reduce its viscosity. The formulation comprises a polymeric material AA which includes —O— moieties pendent from a polymeric backbone thereof and said material is optionally cross-linked. In one embodiment, the formulation may comprise polyvinyl alcohol. In an alternative embodiment, the formulation may comprise a cross-linked polymeric material, such as cross-linked polyvinyl alcohol. After the viscous composition has been transported to a desired location, it may be separated from the other components.

摘要： An additive for a water-based mud drilling fluid or for drill-in fluids comprises a 0.5 wt % solution of 87-89 mole % hydrolysed polyvinylalcohol, having a weight average molecular weight of about 20,000. Use of the additive may reduce susceptibility of a wellbore to blockages, reduce accumulation of accretions between a drill string and wellbore casing, reduce bit-balling and facilitate separation of undesirable insoluble solids from a drilling fluid returned to the surface.
