    摘要: A method of processing azimuthal measurement data includes: receiving a plurality of data values generated by a rotating measurement tool, the measurement tool including at least one measurement sensor and configured to rotate and measure a signal at each of a plurality of azimuthal orientations; associating each received data value with an azimuthal orientation; selecting one or more data values that provide sufficient information regarding a measured signal, each of the selected data values having an associated azimuthal orientation; disregarding azimuthal orientations associated with one or more data values that provide insufficient information regarding a measured signal; and fitting only the selected data values to a sinusoidal curve.

    摘要: A method for generating a flow profile of a wellbore whereby a resistivity tool is run through the wellbore, while the wellbore is being drilled, to sequentially measure and record, at each of a sequence of selected points along the wellbore, a sequential series of resistivities measured while drilling (MWD). Fluid from the wellbore is then allowed to permeate into the formation. The resistivity tool is then run through the wellbore, after the drilling mud has permeated into the formation, to sequentially measure and record, at substantially the same points at which the MWD resistivity measurements were made, a sequential series of resistivities measured after drilling (MAD). For each point, the arithmetic difference between the MWD resistivity and the corresponding MAD resistivity recorded for the respective point is calculated. For each respective point in the sequence of points, the sum of the arithmetic differences for the respective point and each point which follows the respective point in the sequence of points is recorded. A flow profile of the wellbore is generated by plotting the value of the sums calculated for each point of the sequence of points, wherein the magnitude of the permeability of a zone in the formation and, hence, of the potential productive flow from that point in the wellbore, is substantially proportional to the magnitude of the slope of the profile corresponding to that point.

    摘要: A method and apparatus are disclosed for conducting ground or near ground magnetic surveys in which the magnetic field measurements of the earth's total field, a component thereof, or a combination of components thereof, are made at continuous or near continuous (less than 20 feet intervals) measurement intervals. These measurements are recorded in analog or digital format by the apparatus which may include a corresponding chart recorder, recording on chart paper, magnetic tape or any appropriate recording device. The device includes manual switches for advancing the chart, making a recording, making a fiducial mark and for reversing the polarity of recording of the reading from the magnetometer.

    摘要: Methods, apparatus, systems, and computer-readable media are set forth for providing a graphing database for exploration and/or production data, e.g., as used in the oil & gas industry. The graphing database can include multiple different entities that are defined by nodes, node edges, and properties that are generated from information collected by an exploration and/or production system. Entities can be designated as complete when the attribute data associated with those entities satisfy mapping rules for standardizing different types of entities. In this way, end users that access data from the graphing database can receive complete data that is consistently available through a variety of sources.
