摘要： A method is disclosed for producing a single logging-while-drilling (LWD) merged caliper from several indirect LWD borehole size measurements. The merging accounts for the varying validity of each input borehole size measurement as a function of the environment, the formation, and the borehole size itself. In one embodiment, the method includes obtaining a plurality of borehole size measurements from a plurality of LWD sensors and weighting each measurement with varying measurement confidence factors. One embodiment of the method includes determining a set of mathematical equations representative of the responses of the multiple sensors and solving the equation set to determine the borehole size. A computer encoded with instructions for weighting borehole size inputs and iteratively processing the weighted inputs to determine the merged caliper is also disclosed.

摘要： Techniques for calibrating well-logging sensors comprising emitting a first signal into a first calibration substance disposed proximate to the sensor, measuring a first sensor response from the first signal, emitting a second signal into a second calibration substance disposed proximate to the sensor, measuring a second sensor response from the second signal, and determining a sensor response function from the first sensor response and the second sensor response. One embodiment includes providing a well-logging sensor having a known response function, determining an expected range of a quality check response of the sensor using a quality-check substance with known properties, emitting a quality check signal into the quality-check substance, measuring the quality check response from the quality check signal, and comparing the expected range with the quality check response.

摘要： A method for tool path identification in formation evaluation includes obtaining measurements of formation properties in azimuthal sectors for each of a plurality of depth levels; calculating quality factors from the measurements; identifying a centroid or maximum of the quality factors among the measurements in each of the azimuthal sectors for each depth level; and associating the centroid or maximum of the quality factors at each depth level along a borehole to form the tool path. Calculating the quality factors may include parameterizing the measurements according to at least one factor selected from a spine factor, a rib factor, and a volumetric photoelectric factor. A method for determining corrected measurements for formation properties includes identifying a tool path from measurements taken in azimuthal sectors at each depth level along a borehole; and calculating a corrected measurement at the each depth level by averaging measurements in the azimuthal sectors adjacent the tool path.
