Title: Jiefu Chen: Innovator in Wellbore Imaging Technology

Introduction

Jiefu Chen is a prominent inventor based in Cypress, TX (US), known for his contributions to wellbore imaging technology. He holds a total of 5 patents, showcasing his innovative approach to solving complex challenges in the oil and gas industry.

Latest Patents

One of his latest patents is titled "Apparatus and method for wellbore imaging in oil-based mud." This invention features an oil-based mud wellbore imaging apparatus designed to measure formation permittivity and resistivity. It includes a reflectometry-type microwave scanning system that utilizes at least one high-Q microstrip resonator with slots on its top surface. The microstrip resonator is excited by a port fed with electromagnetic signals through a coaxial cable. By detecting the phase of the signal at the port, the formation resistivity and permittivity can be determined, allowing for the generation of corresponding borehole images.

Another significant patent is "Logging while drilling electrical imager and method for measurement in oil-based mud." This invention describes a method and apparatus for creating a borehole image by firing a signal towards a borehole formation using transmitters arranged in both horizontal and vertical arrays. The fired signals engage the downhole formation, and the received signals are analyzed to determine various vertical and horizontal formation parameters, ultimately generating an omni-directional image based on these parameters.
