Title: **Carel W. Hoyer: Innovator in Drilling Technology**

Introduction

Carel W. Hoyer is an accomplished inventor based in London, GB, who has significantly contributed to the field of drilling technology. With two patents to his name, Hoyer has demonstrated his expertise and innovative capabilities by developing methods that enhance drilling efficiency and safety.

Latest Patents

Hoyer's most recent patents are centered around a Rotating Control System and a method for providing differential pressure in drilling operations. His Drill-To-The-Limit (DTTL) drilling method variant applies constant surface backpressure, whether the mud is circulating or not. By utilizing this constant backpressure, the DTTL method allows for the use of lighter mud weights, which effectively maintains cutting carrying ability and keeps boreholes clean. The method is designed to identify the weakest components of the pressure containment system, such as the formation's fracture pressure or the casing shoe leak-off test (LOT). With capabilities of higher rated rotating control devices (RCD), Hoyer's innovations permit disregarding the conventional drilling window's pore pressure limitations, thus revolutionizing fluid development and drilling programs.
