Statoil decided to change their intervention strategy based on the possibilities offered by the Well Tractor®. The willingness to adopt this new technology generates approximately $30 billion a year in value creation for Statoil as they have increased operational efficiency, minimized production losses and maintained maximum possible production by extending reservoir decline. Today, electric line technology has become their preferred intervention solution.

revolutionized the industry when it was introduced to the market. The Well Tractor® facilitated a step change in the technique of deploying logging tools into horizontal and highly deviated wells without the use of heavier intervention methods like coiled tubing or drill pipe.
Welltec® is founded on pioneering work by CEO Jørgen Hallundbæk who envisioned a radical idea to recover oil and gas back in 1987. This innovative thinking led to the Well Tractor® that
Quite unusual in the oil and gas industry, the Well Tractor® was rapidly adopted by operators, in particular North Sea giant Statoil, who quickly spotted the potential in this conveyance revolution. In fact,

Over the years, Welltec® has gradually evolved from a conveyance supplier to a provider of comprehensive oil field services. Today, Welltec® is a globally recognized world leader within well solutions and we have grown solidly to achieve worldwide presence.
Our mission is to develop and deliver solutions which enable our clients to optimize the value of their oil and gas reserves by minimizing reservoir uncertainties and maximizing flexibility. Ultimately, we want to ensure optimal reservoir drainage.
InnovatIon RunnIng In ouR Blood Building on past successes, Welltec® is still a solution-oriented company that sees possibilities where others may see obstacles. For a company so young, Welltec® has been taking home an impressive amount of industry awards for innovative thinking. Our ability to think outside the box has also been widely recognized and demonstrated by application under extreme and harsh conditions; e.g. Welltec® holds the record for deepest water depth using RLWI on electric wireline (2,950 ft. in Gulf of Mexico), performing under 388° F, having achieved the longest distance in one run (34,900 feet) and the longest amount of tractored footage in one trip to the wellsite (423,615 feet). Recently, Welltec® has introduced a series of lightweight electric line solutions that can be performed as riserless operations and that have set new standards for what is achievable. This means that Welltec® delivers riserless lightweight interventions (RLWI) that previously were not possible in the industry.

e-line Clean-out generates $18 million Cost savings Also in the North Sea, we were challenged to clean out a well that was experiencing problems with fill all the way up to surface. In 13 runs, we successfully removed the fill consisting of a resin often used instead of cement. The successful intervention enabled the operator to continue with the planned operation while generating over $18 million in cost savings and deferred production compared to using the alternative.
