Title: Innovations of Arthur C Cheng in Geophysical Engineering
Introduction
Arthur C Cheng is a notable inventor based in Houston, TX (US), recognized for his contributions to geophysical engineering. He holds a total of 3 patents that focus on advanced methods for estimating formation stress and porosity in earth formations. His work has significant implications for the oil and gas industry, particularly in enhancing borehole stability and sand control.
Latest Patents
One of Cheng's latest patents is titled "Estimating formation stress using borehole monopole and cross-dipole." This innovative system and method determine an in-situ stress field based on borehole acoustic measurements. The process involves generating a radially polarized monopole shear-wave in a borehole and analyzing whether it splits into two shear-waves. The difference in velocities between these shear-waves is crucial for determining stress-induced anisotropy around the borehole. Additionally, the patent discloses methods for defining a stress indicator related to rock deformation, which can predict impending rock failure.
Another significant patent is the "Apparatus and method for combined acoustic and seismoelectric logging." This method estimates the porosity of earth formations by measuring acoustic energy and seismoelectric voltages generated in response to that energy. The process involves synthesizing seismoelectric signals from acoustic measurements and adjusting the initial value of porosity until the difference between synthesized and measured voltages reaches a minimum. This innovative approach also includes estimating the conductivity of fluids in the formation's pore spaces.
