  • Estimating cuttings removal
    Patent number: 10060209
    Abstract: A first property, derivable from mass, of a drilling fluid is measured at a point upstream of a cuttings removal device. A second property (also derivable from mass) is measured at a point downstream of the cuttings removal device. A difference between the properties is determined over a period of time to obtain an estimate of the rate of cuttings removal. This allows the property of the drilling fluid before and after cuttings removal to be compared to give an indication of the rate of cuttings removal, which is indicative of the borehole cleaning.
    Type: Grant

    Date of Patent: August 28, 2018
    Assignee: STATOIL PETROLEUM AS

  • Tripeptidyl aminopeptidase
    Patent number: 5821104
    Abstract: The present invention relates to a tripeptidyl aminopeptidase, a DNA construct encoding the tripeptidyl aminopeptidase, a method of producing tripeptidyl aminopeptidase and methods of reducing the tripeptidyl aminopeptidase production in cells in which tripeptidyl aminopeptidase activity is undesirable.
