  • Methods for increasing wellbore strength
    Patent number: 11767737
    Abstract: Disclosed herein are compositions and methods for reducing fluid loss in a well bore, methods for wellbore strengthening and increasing the integrity of the borehole of an oil or gas well. Also disclosed are methods for artificially increasing the temperature of a subsurface formation in the wellbore to increase the apparent wellbore strength. The mechanism for accomplishing this revolves around increasing fracture propagation pressure by actively manipulating thermal wellbore stresses.
    Type: Grant

  • Systems and methods for determining a rheological parameter
    Patent number: 9909413
    Abstract: The present disclosure relates to systems and methods for determining a rheological parameter of a fluid within a wellbore. The methods comprise receiving a plurality of differential pressure measurements of a fluid within a flow region of the wellbore; storing the plurality of differential pressure measurements; generating a curve based on the plurality of differential pressure measurements; and determining the rheological parameter of the fluid using the curve. The systems comprise a conduit arranged in a wellbore; a plurality of pressure sensors along the conduit configured to measure pressure of the fluid within the wellbore; and a processing device. The processing device is configured to: receive a plurality of differential pressure measurements of the fluid from the pressure sensors; store the plurality of differential pressure measurements; generate a curve based on the plurality of differential pressure measurements; and determine the rheological parameter of the fluid using the curve.
