Title: Jarle Varhaug: Innovator in Petroleum Well Technology

Introduction

Jarle Varhaug is a notable inventor based in Ålgård, Norway. He has made significant contributions to the field of petroleum engineering, particularly in the area of casing perforation and cementing techniques. His innovative approach has led to the development of a unique patent that addresses challenges faced in petroleum wells.

Latest Patents

Varhaug 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 also involves positioning the perforating gun at the cemented casing portion and activating 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, followed by washing out the shattered cement. This innovative method enhances the efficiency of well operations.
