Introduction

Fredrik Egerstrom is a notable inventor based in Nacka, Sweden. He has made significant contributions to the field of drilling technology, holding a total of 3 patents. His work focuses on improving the efficiency and effectiveness of down-hole drilling methods.

Latest Patents

Egerstrom's latest patents include a "Method and device for directional down-hole drilling." This invention addresses the challenges of drilling curved holes, particularly in mining applications. The method utilizes a flexible continuous drill tube that supports a down-hole assembly with a drill bit. This innovative approach minimizes the occurrence of 'stick slip' during directional drilling by holding the drill support fixed at its proximal end while allowing for controlled rotation of the drill bit.

Another significant patent is the "Liquid driven downhole drilling machine." This invention features a guiding bushing for the drill bit that is rotatably journaled in the housing. It employs a one-way coupling to connect to a turning sleeve with axial ridges, which form turning pistons. This design allows for efficient indexing of the drill bit, ensuring that the contact points with the rock change with each impact, thereby enhancing the drilling process.
