Title: Innovations of Yunsheng Li in Borehole Imaging

Introduction

Yunsheng Li is a prominent inventor based in Dhahran, Saudi Arabia. He has made significant contributions to the field of borehole imaging, holding a total of 6 patents. His work focuses on enhancing the accuracy and efficiency of subsurface formation analysis during drilling operations.

Latest Patents

One of his latest patents involves generating synthetic borehole image logs. This system and method utilize logging rate of penetration (ROP) data, resistivity data, and gamma ray data while drilling a borehole. The process includes determining an effective dip angle of the subsurface formation and generating a depth shift table based on this angle and the well deviation angle. The generated datasets have higher sampling rates than the logged data, allowing for the creation of synthetic borehole images that are oriented with respect to a reference point of the borehole.

Another notable patent focuses on the creation of near-bit gamma ray images from a gamma ray curve. This method involves determining real-time azimuthal density data during well drilling. An azimuthal density data set is generated with a greater sampling rate than the real-time data. A high-resolution sector near-bit gamma ray image is then produced, oriented to the top of the wellbore, enhancing well placement accuracy.
