Title: Innovations in Subsea Production: The Contributions of David C. Lucas

Introduction: David C. Lucas, an inventive mind based in The Woodlands, TX, has made significant strides in enhancing subsea production processes. With two patents to his name, Lucas specializes in innovative methods that address challenges within the oil and gas industry.

Latest Patents: One of David's notable patents is a "Method for managing hydrates in a subsea production line." This patented method focuses on managing hydrates in a subsea production system, which involves several components: a host production facility, a control umbilical, at least one subsea production well, and a single production line. The process begins with producing hydrocarbon fluids and subsequently shutting in the production line. It entails depressurizing the line to reduce gas concentration within the produced fluids and then repressurizing it to return any remaining gas to solution. Additionally, the method incorporates the use of displacement fluids from a service line, specifically a hydrocarbon-based fluid containing a low dosage hydrate inhibitor.

Another significant patent by Lucas is similar in nature, also titled "Method for managing hydrates in a subsea production line." This innovation describes a multifaceted approach to subsea production, encompassing pumping a displacement fluid into chemical injection tubing, followed by its distribution throughout the production system. This method ensures that produced fluids are displaced efficiently before hydrate formation can occur, utilizing chemical inhibitors strategically placed prior to the introduction of displacement fluids.

Career Highlights: David C. Lucas is associated with ExxonMobil Upstream Research Company, where he contributes to various advancements in oil and gas extraction methods.
