Patent number: 7240537Abstract: The present invention deals with a method which allows to determine the wall friction profile along pipes transporting liquids, particularly petroleum industry liquids, by measuring the pressure transients induced by fast changes in the flow rate. This method is applicable to pipes in which the discharge pressure is greater then the bubble point of the transported liquid and, in any case, when free gas is absent in the pipe.Type: GrantFiled: July 30, 2002Date of Patent: July 10, 2007Assignees: ENI S.p.A., Enitechnologie S.p.A.Inventors: Alberto Di Lullo, Sebastiano Correra, Vittorio Rota, Gilberto Toffolo, Martin Bartosek

Patent number: 6642056Abstract: A process is described for determining the stability of asphaltenes in oil fields, which comprises the following steps: a) titrations of stock tank oil are carried out; the values measured are then used, together with physico-chemical analyses of the stock tank oil, to thermodynamically characterize the asphaltenes and the heavy oil fraction; b) using the physico-chemical analyses of live oil, the experimental data relating to its phase behavior are interpolated in order to provide a better representation by means of an equation of state; c) using the equation of state thus calibrated and the characterization of the asphaltenes, the stability of the latter is verified in relation to the temperature and pressure of live oil, using the equation describing the behavior of a sterically stabilized colloid.Type: GrantFiled: September 22, 2000Date of Patent: November 4, 2003Assignee: Enitecnologie S.p.A.Inventors: Sebastiano Correra, Francesca Donaggio, Delfina Bersano
