Iain Maxted

Chief Technology Officer

Following a degree in mining engineering from the University of London’s Imperial College and two years post-graduate study at Cardiff University’s Department of Mineral Exploitation, Guardian’s Technical and Managing Director, Iain Maxted spent the first six years of his oil industry career as a field engineer with Schlumberger. Wide experience of both onshore and offshore operations gained through positions in Denmark, Ireland, the UK, Norway, Syria and Egypt led to him being selected as a specialist engineer for deep, high-temperature operations with Shell in the Egyptian Western Desert.


After leaving Schlumberger in 1992, Iain joined Sondex (now GE) and by 1995 was appointed General Manager.


Iain left Sondex in 1995 and together with Guardian’s Operations Director, Suzannah Bourne, was requested by a number of service companies to develop various downhole intervention products. The first of these was the Addressable Release Tool which has become hugely successful and an industry standard. Iain has also been responsible for developing the shortest PL string in the world, redeveloping the production logging capability for one of the major service companies as well as the host of other production logging and Ballistics Delivery System products manufactured today by Guardian.
