Title: Innovations of Per A Vatne in Drilling Technology

Introduction

Per A Vatne is a notable inventor based in Kristiansand, Norway, recognized for his contributions to drilling technology. With a total of 18 patents to his name, Vatne has made significant advancements in fluid pressure-driven tools designed for drilling in hard formations. His innovative designs have the potential to enhance efficiency and effectiveness in drilling operations.

Latest Patents

Among his latest patents is a fluid pressure-driven, high-frequency percussion hammer specifically designed for drilling in hard formations. This percussion hammer features a hammer piston with a relatively large and longitudinally extending bore, which minimizes flow resistance for drilling fluid during the return stroke. The bore can be closed in the upstream direction by a valve plug that follows the hammer piston during its stroke. The valve plug is controlled by a long and slender valve stem, which can stop the valve plug by approximately 75% of the full stroke length of the hammer piston. This design allows the bore to open, enabling fluid to flow through it, while the inherent tension spring properties of the valve stem ensure rapid return of the valve plug, facilitating good flow during the return of the hammer piston.
