Title: Innovations in Drilling Fluids by William M Duncan, Jr.
Introduction
William M Duncan, Jr. is an accomplished inventor based in Nueces County, TX (US). He has made significant contributions to the field of drilling fluids, with a focus on developing additives that enhance performance while minimizing environmental impact. With a total of 2 patents, Duncan's work is recognized for its innovative approach to drilling technology.
Latest Patents
Duncan's latest patents include a drilling fluid and drilling fluid additive that comprises a monocyclic terpene, preferably d-limonene or dipentene, along with a bicyclic terpene such as 3-carene, or mixtures thereof. This additive is mixed in a water-based drilling mud in the range of 1-8% by volume. The additive offers several advantages, particularly improved penetration rate, high lubricity, and low toxicity. Another notable patent is for a low toxicity terpene drilling fluid, which consists of 1-8% of an additive comprising saturated terpenes, a mixture of saturated terpenes, or a combination of saturated and unsaturated terpenes. This drilling fluid is substantially non-toxic, boasting an LC-50 greater than 30,000 ppm, and preferably greater than 100,000 ppm. The most economical additives are a mixture of saturated and unsaturated terpenes, with at least 30% saturated terpenes, providing a significant advantage in terms of low toxicity compared to unsaturated terpene drilling fluids.
