Title: Innovations by Hans H Rehbock

Introduction

Hans H Rehbock is a notable inventor based in Houston, TX (US). He has made significant contributions to the field of downhole milling technology, holding a total of 4 patents. His work primarily focuses on enhancing the efficiency and safety of downhole operations.

Latest Patents

One of his latest patents is a window-cutting system for downhole tubulars. This invention features a guide lug designed for a starting or window mill, which is positioned at the upper end of the whipstock. The design includes a back-up shoulder to counteract any tendencies of the mill to whirl. Additionally, a taper is incorporated to guide the mill toward the casing for cutting the window. The lug is specifically configured to be worn by a guide for the window mill or starter mill, rather than being milled away. This innovation protects the upper sections of the whipstock from the mill, ensuring that any holes or projections for subsequent retrieval of the whipstock remain functional at the conclusion of the milling process.

Another significant patent by Rehbock is a torque control device for downhole milling. This invention provides a support mechanism for a mill, particularly useful with a whipstock and driven by a downhole motor supported by coiled tubing. The support mechanism includes a wearable ring adjacent to the cutting structure, which keeps the rotating blades away from the whipstock face and oriented toward the casing to be cut. As the milling progresses, the support mechanism wears away, allowing the mill to advance into the casing and complete the formation of the window or opening.
