Title: Bjørn Tore Torvestad: Innovator in Petroleum Engineering

Introduction

Bjørn Tore Torvestad is a notable inventor based in Stavanger, Norway. He has made significant contributions to the field of petroleum engineering, particularly through his innovative patent that addresses challenges in well casing.

Latest Patents

Torvestad holds a patent for a toolstring and method for inner casing perforating, shattering annulus cement, and washing the first annulus in a second casing. This method involves sealing a partly or entirely annulus-cemented casing portion of a first casing in a second casing in a petroleum well. The process includes running a drill pipe string-conveyed perforating gun with a cement shattering device into the well. It positions the perforating gun at the cemented casing portion and activates first, shallow-perforating charges to create perforations through the casing. The cement shattering device is then activated to disintegrate the cement within the perforated annulus portion. A washing tool is run along the perforated casing portion to wash out the shattered cement. The washed-out casing portion may then be cut using a cutter tool or cemented using a cementing tool, or a combination of both.
