Introduction
Donald J Hilliker is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of borehole logging technology. With a total of 2 patents, Hilliker's work focuses on enhancing the efficiency and accuracy of measurements in drilling operations.
Latest Patents
Hilliker's latest patents include a Borehole Logging Tool and a Method for Processing Signals from an MWD Electromagnetic Resistivity. The Borehole Logging Tool is designed to generate both flexural wavefields and compressional wavefields in the sidewall formations encountered by a borehole. This innovative assembly consists of a sonde made up of multiple segments that can rotate axially with respect to one another. Each of two segments contains a compartment housing a dipole bender bar transmitting transducer, while additional segments include binaurally sensitive receiver transducers. The design also features monopole transmitting and receiving transducers, along with an acoustic isolator that separates the transmitting transducers from the receiving ones.
The Method for Processing Signals from an MWD Electromagnetic Resistivity introduces an adaptive deconvolution method aimed at enhancing the vertical resolution of measurements taken by an MWD electromagnetic resistivity logging tool. This tool measures the voltage differences induced in spaced-apart receiver coils. The method involves deriving a deconvolution filter based on the weighted average of measured phase differences, which helps to spatially deconvolve the measurements and reduce shoulder-bed effects.
