Title: Philip Trunk and His Drill-Bit Invention.
Introduction
Philip Trunk is an inventor based in Houston, Texas, and is associated with Schlumberger Technology Corporation. His patent work addresses drill-bit design, with a focus on how cutting elements engage the material being drilled.
Latest Patents
Trunk is named on 1 patent: “Variable Cutting Element Exposure in a Cutting Tool.” The patent describes a drill bit with a roller cone carrying cutting inserts and a blade carrying fixed cutting elements. The inserts form a rolling cutting profile, while the fixed elements define a separate profile. The rolling profile extends above the fixed profile, with that exposure increasing farther from the bit’s central axis. This arrangement provides a way to vary cutting-element exposure across the bit’s radial direction.
Career Highlights
The available information identifies Trunk’s work with Schlumberger Technology Corporation and documents his contribution to drill-bit technology through this patent. The invention concerns the configuration of cutting elements in a tool designed to rotate during drilling.
