  • Continuous porous bed centrifuge
    Patent number: 7708681
    Abstract: A porous bed centrifuge for continuous separation of immiscible liquids, for example water and mineral oil/petroleum, obtained by a modification to conventional disk centrifuges for increasing their efficiency, wherein the disks have been substituted by a filling of solid particles that act as a filtrating and coalescent bed.
    Type: Grant
    Filed: November 3, 2005
    Date of Patent: May 4, 2010
    Assignee: ENI S.p.A.

  • Method for the determination of the wall friction profile along pipes by pressure transients measurements
    Patent number: 7240537
    Abstract: 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.

  • Non-damaging drilling fluids
    Patent number: 6495493
    Abstract: Water-based drilling fluid comprising: (a) water, (b) at least one biopolymer of the polysaccharide type, (c) at least one filtrate reducer selected from starches with different cross-linking degrees in presence of cellulose microfibers, (d) optionally a hydrosoluble polymeric surface-active agent having an HLB from 10 to 16, preferably from 11 to 14.
