Title: Inventor David Matus: Pioneering Innovations in Reverse Circulation Cementing

Introduction

David Matus is an accomplished inventor based in Collin, TX, USA. He holds two patents that reflect his expertise in engineering methods essential to the energy industry, particularly in wellbore operations.

Latest Patents

David's innovative work has culminated in two significant patents focused on reverse circulation cementing. The first patent, titled "Cementing a liner using reverse circulation," describes a method for cementing a liner in a wellbore that extends through subterranean formations. The patented system employs a running tool with an expansion cone, an annular isolation device, and a reverse circulation assembly. This unique setup allows the annular isolation device to be set against the casing, while a valve, such as a dropped-ball valve, opens reverse circulation ports for the cementing operation. The process culminates in the cementing of the liner annulus, efficiently utilizing reverse circulation techniques.

The second patent, "Reverse circulation cementing system for cementing a liner," closely mirrors the innovations found in the first. It introduces a running tool equipped with similar components, including a release assembly and a sliding sleeve valve that operates on a dropped-ball mechanism. This system also specifies the restoration of conventional circulation after the cementing operation is complete, ensuring the integrity and efficiency of the wellbore processes.
