Patents by Inventor Ali Karimi Vajargah

Ali Karimi Vajargah has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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

  • Patent number: 11466554
    Abstract: Embodiments are directed to managing and improving a drilling and completions process at a hydrocarbon extraction site, and to optimizing resource allocation at a hydrocarbon extraction site/region. In one scenario, a computer system accesses data generated by hardware sensors implemented by drilling and completion equipment at a hydrocarbon extraction site. The computer system formats the sensor data into a form readable by a data mining algorithm, and mines the formatted sensor data to identify characteristics related to the drilling and completion process. The computer system also accesses and integrates historical data related to the drilling and completion equipment at the hydrocarbon extraction site. The computer system then computes drilling and completion performance indicators that identify inefficiencies based on the characteristics identified for the equipment and based on the accessed historical data. Then, a remediation step is performed to resolve the identified inefficiency.

  • 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.
