Abstract: A process of recovering oil from an oil-bearing formation which process comprises injecting into the formation an aqueous enhanced oil recovery formulation comprising water and an enhanced oil recovery additive, which process comprises supplying water via a first conduit to a flow control valve, combining water which has passed the flow control device with an additive solution containing at least 3000 ppm of the enhanced oil recovery additive to obtain the aqueous enhanced oil recovery formulation, injecting the aqueous enhanced oil recovery formulation into the formation via a first well, producing from the formation via a second well a mixture and separating oil from the mixture produced.

Abstract: A method of producing fluid from a formation containing hydrocarbons in which an aqueous polymer preflush fluid is injected into the formation followed by injection of an aqueous polymer displacement fluid, where the aqueous polymer preflush fluid has a total dissolved solids content that is greater than the total dissolved solids content of the aqueous polymer displacement fluid.

Abstract: Recovering oil from a subterranean formation is disclosed, comprising processing a source water to produce a processed water stream and a reject water stream; injecting a first fluid into an injection well toward a first downhole exhaust, wherein the first fluid comprises the processed water stream; and injecting a second fluid into the injection well toward a second downhole exhaust, wherein the second fluid comprises the reject water stream or a produced water stream, wherein the first fluid is separated from the second fluid within the injection well; and producing oil via a production well.

Abstract: A method for inhibiting freezing of low salinity water (H2O) in a subsea low salinity water injection flowline comprises providing the flowline with a pressure control system, which may include a high pressure pump and a pair of pressure shut in valves, which maintains an elevated fluid pressure within the flowline throughout low salinity water injection operations and shut in periods, during which periods the flowline remains filled with pressurized non frozen low salinity water (H2O) that may have a temperature of about ?2 degrees Celsius.

Abstract: Method of detecting cracks in an object of an electrically conducting material that is covered by a non-conductive layer using a probe comprising a transmitter coil for inducing eddy currents in the object and a receiver coil comprising selecting a set of points of the object which are to be inspected; and which method further comprises for each point positioning the probe at the point, activating the transmitter coil to induce eddy currents in the object; creating a record of the signal provided by the receiver coil over a period of time; and examining the record and comparing it to reference records, wherein the presence or absence of a crack can be inferred from the comparison.

Abstract: The present invention relates to a device for measuring the value of a parameter relating to an electrically conductive object. Such a parameter can be the electric conductivity or the degree in which the material has changed under the influence of external conditions. Alternatively the parameter is the quality of a weld or the thickness of the object.

Abstract: A method of inspecting an electrically conductive object so as to detect the presence of an anomaly using a probe comprising a transmitter coil and a receiver coil, which method comprises the steps of: (a) selecting a set of points on the near surface of the object that are to be inspected; (b) selecting a first inspection point from the set; (c) positioning the probe at the selected inspection point, inducing eddy currents in the object and determining a characteristic value, &PHgr;, of the electromagnetic field generated by the eddy currents; (d) selecting a next inspection point from the set and repeating step (c) until all inspection points have had their turn; and (e) inferring that an anomaly is present at an inspection point if the characteristic value &PHgr; differs significantly from a norm.

Abstract: Detecting the presence of an anomaly in or near an object using a probe comprises: a) selecting a set of points on the near surface which are to be inspected, and selecting a first direction and a second direction; b) selecting a first inspection point from the set; c) positioning the probe at the selected inspection point in the first direction, inducing eddy currents in the object and determining a characteristic value of the electromagnetic field; d) positioning the probe in the second direction at the selected inspection point, inducing eddy currents in the object and determining a characteristic value of the electromagnetic field; e) selecting a next inspection point from the set and repeating steps c) and d) until all inspection points have had their turn; and f) inferring that an anomaly is present at an inspection point if a combination of the characteristic values in the first and second direction deviates significantly from a norm.
