Welltec

Jørgen Hallundbæk, the founder and CEO of Welltec, conceived the idea behind the Well Tractor while he was a graduate student at the Technical University of Denmark. The idea consisted of eliminating the large and expensive amounts of equipment needed for conveying tools and performing interventions in oil and gas wells. The Well Tractor enabled operators to reach the horizontal part of oil and gas wells and getting past the deviated sections using standard electrical wireline. Generally, wells are considered deviated when they reach an inclination higher than 60°. Previously, interventions in horizontal and deviated wells were considered a lengthy and costly process.

New technology in the oil and gas industry is not readily accepted due to the costs of failure. The multinational oil company Shell has estimated that new technology requires 20–30 years to achieve broad acceptance . The Well Tractor performed its first job in 1996, an operation that took place in the North Sea offshore Norway .

In 2003 the company went from being a sub contractor to other service companies to being a direct contractor to the operators.

Today, Welltec has more than 45 offices and service facilities worldwide including Headquarters located in Allerød, Denmark.

In July 2007, Welltec partnered with Summit Partners, a growth capital private equity investor.[2]

Welltec provides a range of services to international oil and gas companies from the drilling & evaluation phase to the completion and production phases. Services are delivered on wireline. The proprietary technology is developed and manufactured at headquarters in Allerød.

Services solve problems across different well types and environments. Welltec’s technology is applicable in vertical, horizontal, deviated and technologically advanced wells. Challenging conditions may be wells such as deepwater, Subsea, extended reach, high-yield, heavy oil, Arctic conditions and unconventional gas environments.

Wireline technology is by many people in the oil and gas industry viewed as a focus area with potential for development, and Welltec has expanded their technology portfolio during the years. Most services are performed with the Well Tractor that conveys logging tools or intervention tools to the desired point in the well where an intervention is needed. Originally, the Well Tractor was designed as a tool conveyor but today it is also able to perform interventions.

Initially, the Well Tractor formed Welltec’s tool portfolio, but in 2003 the so-called mechanical down hole services were added to the portfolio of technology. These intervention services are intended for electric wireline operations such as valve manipulation, scale milling, setting and pulling plugs, milling plugs and sand bailing. To date, Welltec has developed and produced seven tools with different areas of operation. Apart from the Wireline Well Tractor, a Coiled tubing Well Tractor has been manufactured, which instead of running on wireline is fluid-driven. The mechanical down hole services consist of the Well Stroker, the Well Key, the Well Cleaner, the Well Miller and the Welltec Release Device. All tool names are registered trademarks of Welltec.
