Abstract:
1. A method for estimating an azimuthal dependence of a parameter of a borehole using logging sensor measurements acquired as a function of azimuth of said logging sensors, the method comprising: (a) rotating a downhole tool in a borehole, the tool including at least one logging sensor and at least one azimuth sensor, data from the logging sensor being operable to assist determination of a parameter of the borehole; (b) causing the at least one logging sensor and the at least one azimuth sensor to acquire at least one data pair, each data pair comprising a logging sensor measurement and a corresponding azimuth; (c) processing a convolution of selected data pairs with a predetermined filter to determine convolved logging sensor data for at least one azimuthal position, the filter being selected from the group consisting of low pass filters, high pass filters, and bandpass filters.
