  • Patent number: 8756018
    Abstract: A method for determining movement of a fluid contact in a subsurface reservoir includes measuring azimuthally sensitive resistivity at a first time from within a wellbore penetrating the subsurface reservoir. A first position of the fluid contact with respect to the wellbore is determined using the azimuthally sensitive resistivity measurements. After a selected time, the measuring azimuthally sensitive resistivity from within a wellbore penetrating the subsurface reservoir is repeated. Movement of the fluid contact from the first position is determined using the repeated azimuthally sensitive resistivity measurements.
    Type: Grant

  • Patent number: 8567526
    Abstract: A method of steering a drilling operation of a well using rock stress measurements. The method includes obtaining well data from at least one logging while drilling tool in the well, where the well data includes stress direction information, generating, using a central processing unit (CPU), a well trajectory using survey data from the well, where the well trajectory includes a borehole direction, determining, using the CPU, a direction of minimum horizontal stress using the well data, and comparing, using the CPU, the direction of minimum horizontal stress to the borehole direction to determine that a directional criteria is not satisfied. The method further includes in response to determining that the directional criteria is not satisfied, generating an updated well trajectory that satisfies the directional criteria and adjusting the drilling operation using the updated well trajectory.

  • Patent number: 8095318
    Abstract: A method for determining dip of rock formations penetrated by a wellbore using multiaxial induction measurements and imaging measurements made from within the wellbore includes estimating dip from the multiaxial induction measurements. Dip is also estimated from the imaging measurements. The dip is determined by combining the induction and imaging measurements.

  • Patent number: 7876705
    Abstract: A Single Well Predictive Model (SWPM) software based computer system stores a Single Well Predictive Model (SWPM) software therein. When the SWPM software is executed, the SWPM computer system will: (1) automatically produce a first specific workflow comprised of a first plurality of software modules in response to a first set of user objectives and automatically execute the first specific workflow in response to a first set of input data to produce a first desired product, and (2) automatically produce a second specific workflow comprised of a second plurality of software modules in response to a second set of user objectives and automatically execute the second specific workflow in response to a second set of input data to produce a second desired product.
