  • Patent number: 9933541
    Abstract: Formation properties in a vertical section of a wellbore are determined by considering the vertical section as consisting of one or more segments. Measurements are obtained with a directional resistivity tool at two or more measurement stations within each segment for which the complex 0th harmonic coefficients for the obtained measurements are non-trivially different from one another. For each such segment, the phase shift and attenuation are determined using the complex 0th harmonic coefficients obtained for that segment and an inversion is performed for the formation properties using the determined phase shift and attenuation for that segment. Formation properties for that segment may be output to a display or memory storage device. For certain segments, one or more gain factors may be obtained. The gain factors are used to correct the measured voltages for certain neighboring segments and the corrected voltages inverted to obtain anisotropy and formation structure.

  • Patent number: 9845671
    Abstract: Methods, systems and products for evaluating a downhole component condition for a drilling assembly in a borehole. Methods include estimating a bending moment on the component at a selected depth along the borehole; estimating a number of rotations of the component at the selected depth; and estimating the condition of the component using the estimated bending moment and the estimated number of rotations at the selected depth. Estimated bending moment may be derived from a borehole model using an estimated deviation on a selected length of the borehole about the selected depth. The condition may be accumulated fatigue or estimated remaining useful life. Estimating the condition may include tracking a total estimated number of rotations wherein the component is subjected to bending moment values in a corresponding moment window, which may be greater than a predetermined threshold bending moment. Weight factors may be associated with at least one moment window.

  • Patent number: 9429002
    Abstract: Systems and methods for controlling an ESP installed in a well. The ESP is operated at a first voltage, and the current actually drawn by the ESP motor is monitored and compared to an expected current. If the actual current differs from the expected current, the actual horsepower load on the ESP motor is determined by multiplying an expected horsepower load by the ratio of the actual current to the expected current. A load saturation curve for the actual horsepower load is determined, and a voltage is identified on this curve at which the corresponding current is minimized. The ESP motor is then operated at this new voltage to optimize the efficiency of the motor.

  • Patent number: 9316053
    Abstract: A computer-readable medium including program instructions for drilling a borehole. When the program instructions are executed by one or more processors of a computer system operatively associated with a drill rig, the program instructions cause the processor to carry out the steps of initiating a drilling phase and monitoring a drill parameter during the drilling phase. The drill parameter includes at least one of drill rotational speed, drill torque or number of drill retractions. The program instructions further cause the processor to carry out the step of determining whether the monitored drill parameter is within a predetermined specification for the monitored drill parameter in order to choose a drilling phase defect mitigation routine. After implementing the drilling phase defect mitigation routine, the processors carry out the step of resuming the drilling phase.

  • Patent number: 9310508
    Abstract: Various logging-while-drilling (LWD) systems and methods provide resistivity logging coupled with deep detection of elongated anomalies at acute angles, enabling effective geosteering without disrupting drilling operations and without requiring intervention in the operations of the existing well. One LWD system embodiment employs a tool having tilted antennas as the transmitter and the receiver, where at least one of the antennas is placed in the vicinity of the bit, making it possible to detect existing wells at distances of 50-100 feet. In some cases, the detection distance is increased by enhancing the visibility of the existing well using a contrast fluid treatment on target well, either to fill the bore or to surround the well with treated cement or fluids that invade the formation. At least one inversion method separates the inversion of formation parameters from the inversion of parameters specifying distance, direction, and orientation of the existing well.
