The real-time bit wear prediction is made by using the real-time drilling data to predict a bit efficiency factor and to detect changes in the bit efficiency factor over time. These predictions may be used to adjust drilling parameters in the drilling operation in real-time, subject to override by the operator. The methods and systems may also include determining various downhole hydraulics parameters and a rotary friction factor.

  • Patent number: 8977501
    Abstract: Provided are a system and method for identifying planned markers while drilling a borehole. In one example, the method includes obtaining a plan containing planned markers that each corresponds to a baseline marker from an existing well. Each of the baseline markers corresponds to a waveform from a log file obtained from the existing well and is associated with a waveform representation of the corresponding waveform. Each of the planned markers is associated with an estimated true vertical depth (TVD) value. A second log file corresponding to the borehole is obtained that contains waveforms representing formation information detected within the borehole. The second log file is scanned for a planned marker based on the estimated TVD value and the waveform representation of the baseline marker corresponding to the planned marker. At least one match may be identified and reported for the planned marker.

  • Patent number: 8944183
    Abstract: The present disclosure is related to apparatuses and methods measuring and processing a characteristic of subsurface earth formations penetrated by a borehole. More specifically this present disclosure relates to a method and apparatus for measuring and processing an acoustic characteristic such as formation shear wave velocity of subsurface sonic waves after these waves traverse earth formations adjoining a borehole or passing through a portion of the subsurface. The apparatus may include: a bottomhole assembly, a drill bit configured to generate an acoustic signal, at least two acoustic detectors, and a processor. The acoustic signal may include a specific multipole signal that may propagate through an earth formation along the borehole. The method may include use of the apparatus, including steps for estimating a shear velocity of the acoustic signal using signals from the at least two acoustic detectors.

  • Patent number: 8922387
    Abstract: A generally three-part EM gap sub comprising a first conductive cylinder incorporating a male tapered threaded section, a second conductive cylinder incorporating female tapered threaded section, both axially aligned and threaded into each other is described. One or both tapers incorporate slots whereby non-conductive inserts may be placed before assembly of the cylinders. The inserts are designed to cause the thread roots, crests and sides of the tapered sections of both cylinders to be spatially separated. The cylinders can be significantly torqued, one into the other, while maintaining an annular separation and therefore electrical separation as part of the assembly procedure. The co-joined coaxial cylinders can be placed into an injection moulding machine wherein a high performance thermoplastic is injected into the annular space, thereby forming both an insulative gap (the third part) and a strong joint between the cylinders in the newly created EM gap sub.

  • Patent number: 8917094
    Abstract: Downhole tools and techniques acquire information regarding nearby conductors such as pipes, well casing, and conductive formations. At least some method embodiments provide a current flow along a drill string in a borehole. The current flow disperses into the surrounding formation and causes a secondary current flow in the nearby conductor. The magnetic field from the secondary current flow can be detected using one or more azimuthally-sensitive antennas. Direction and distance estimates may be obtainable from the azimuthally-sensitive measurements, and can be used as the basis for steering the drillstring relative to the distant conductor. Possible techniques for providing current flow in the drillstring include imposing a voltage across an insulated gap or using a toroid around the drillstring to induce the current flow.
