Patent number: 11085274Abstract: A system for optimising injection of a diluent to one, some or all of one or more wells comprising a downhole pump and holding means for the diluent, said holding means being connected to the or each well via one or more injection lines through which the diluent may be pumped by diluent injection means, characterised in that said system comprises measurement means for real time measurement of one or more production performance parameters, and measurement of the rate of injection of the diluent; and means for optimising the injection of the diluent to at least one of said one or more wells on the basis of: (i) means for making controlled variations of the diluent injection into the at least or each well; (ii) means for the processing of the real time measurements of the production performance parameters affected by these variations to determine any necessary adjustment of the injection of the diluent towards an optimal value; and (iii) if required, making the corresponding physical adjustment of the injectionType: GrantFiled: October 22, 2015Date of Patent: August 10, 2021Assignee: STATOIL PETROLEUM ASInventors: Alexey Pavlov, Kjetil Fjalestad

Patent number: 10890055Abstract: The present invention provides a method for inverting oil continuous flow to water continuous flow and reaching one or more desired production parameters in a well producing fluid containing oil and water or inverting oil continuous flow to water continuous flow and reaching one or more desired transport parameters in a pipeline transporting fluid containing oil and water wherein there is a pump in the well or transport pipeline, comprising the following steps: (a) reducing the pump frequency until either inversion from oil continuous production to water continuous flow is achieved or a predefined stopping condition is reached; (b) if inversion has not been achieved in step (a), adjusting the wellhead pressure in the well or the pressure at the reception side of the transport line to achieve the inversion; (c) stabilising the flow at the condition reached in steps (a) or (b); and (d) carefully adjusting one or both of the wellhead pressure and pump frequency to reach the one or more desired production parametType: GrantFiled: April 27, 2015Date of Patent: January 12, 2021Assignee: STATOIL PETROLEUM ASInventors: Alexey Pavlov, Kjetil Fjalestad

Patent number: 10125584Abstract: A method for operating an electrical submersible pump, ESP, lifted well, the method comprising: measuring a characteristic of the well or a characteristic of a device associated with the well; generating a first control signal for instructing a change in the operation of the ESP; generating a second control signal for instructing a change in the operation of a further device associated with the well; wherein a degree of change in each of the first and second control signals is dependent on the outcome of the measuring and on a known effect caused by sending at least one of said first control signal to the ESP or said second control signal to the further device associated with the well; and sending the first control signal to the ESP and the second control signal to the further device associated with the well.Type: GrantFiled: November 14, 2013Date of Patent: November 13, 2018Assignee: STATOIL PERTROLEUM ASInventors: Elvira Marie Bergheim Aske, Morten Fredriksen, Alexey Pavlov, Kjetil Fjalestad, Dinesh Krishnamoorthy, Petter Tøndel, Yilmaz Türkyilmaz

Patent number: 6433506Abstract: A sensorless control system for an induction motor employs direct tracking of torque and flux regulation to achieve improved motor control without the need for transformation to the rotor flux related frame. A novel torqueflux dynamic model used to implement the control method employs stator voltage as an input, and achieves separation of torque and flux regulation. An alternate regulation method better suited for slow reference signals relies on a steady state solution of the dynamic model.Type: GrantFiled: March 29, 2001Date of Patent: August 13, 2002Assignee: Ford Global Technologies, Inc.Inventors: Alexey Pavlov, Alexander T Zaremba
