Who We Are

Our Mission IESL was established in 1994 after the we found that many good analytical tools were yet to be used by clients to optimise their drilling and production strategies. As a consequence, IESL has continued to develop ways to help our clients better understand their assets and make better informed decisions which save time and money. To this end IESL constantly monitors the developments in the areas of Geomechanical Analysis, Drilling and Production and looks to introduce the latest thinking and analytical models that are the right balance between robustness and cost-effectiveness. We believe our clients should get the right, unbiased decision making information while not being "tied" to either equipment or service providers. Others may offer what they believe are similar services but are often subsidised by greater projects for the client. This means clients eventually pay for inflated overheads. We also understand the commercial pressures and drivers our clients are working under. Our success has always been driven by quality work. We are not ventured or being pushed to have an "exit strategy". Our staff enjoy the work they do and are under no pressure to "sell on" more work. Due to the nature of our work, we tend to home grow our people as this is the only way we find we can deliver the quality of work our clients want. We keep our operations simple and don't expect our clinets to pay for extravagant overheads but prefer instead to get good honest personalised work from us. Our future is organic growth with constantly evolving and expanding capabilities - instead of creating solutions looking for problems, we develop a deep understanding of our clients problems in order to deliver appropriate solutions. Although primarily an analytical consultancy, we also design tools, develop databases and train others in the capabilities we have - all linked to the issues our clients have.

Together, we develop a synergy with our customers that ensures reliability, continuity and high level of excellence in our work.
Management Team
	Juan J. Tovar D. born in Venezuela, is founding member and director of IESL. A mechanical engineer from the UCV in Venezuela, he worked for Schlumberger Dowell in Libya, UAE, Algeria, Norway and the UK in operations, technical and management positions for 9 years. While at Schlumberger, he returned to University in Edinburgh to get a M.Sc. in Petroleum Engineering from Heriot-Watt working on sand production and associated completion problems. Spent two years in Italy where he was R & D and technical services manager for Italog, a subsidiary of the Geoservices group. In 1993 returned to the UK to found IESL with Jeff Callander and implement joint ideas for innovation and technologies that were shared since their time in the field. Have contributed to build IESL with a number of patents and other IPR that today form the core portfolio of IESL technologies. Also a director of Innovative Knowledge Ltd, he specialise in well completion, rehabilitation and intervention particularly for sandstone reservoirs. Juan lectures to a variety of commercial clients and MSc courses on sand production and management strategies, and is favoured due to his ability to breakdown complex problems into practical solutions. From 2003 to 2006 Juan was based in Houston, Texas where he contributed to the expansion of the company in Latin America, returned to the Aberdeen in July of 2006 where he is currently the Operations Director for the Group overseeing technology development and well engineering work. Juan is the author of over 20 publications in the areas of well construction, completion and Geomechanics, he continues to be involved in Knowledge transfer for Industry and Academia as associate Lecturer at The Robert Gordon University in Aberdeen and Petroleos de Venezuela S.A. in Venezuela.
	Jeff Callander, born American but dual nationality British, is a founding shareholder and director of IESL. Although born in the USA, he grew up in Latin America and only returned to the USA for university where he obtained a BSc in Mechanical Engineering. Jeff began his career with Schlumberger working in the Amazon, North Sea and West Africa as well as Schlumberger's manufacturing and research facilities in France. Following Schlumberger, Jeff completed an MBA at the London Business School and subsequently took over a division of Abbott Laboratories in the UK. He then returned to the oil industry to set up IESL with Juan Tovar as both shared a vision of potential improvements that could be offered to the industry of better engineering and innovative thought.

Sand	The network's purpose is to "Communicate successful methods and gaps of managing sand in the North Sea to allow the continued development and operation of offshore fields". The network is open to all who would add value and benefit from membership to such a network. IES Global is a strong supporter of the network.
SPE	The Society of Petroleum Engineers is a rich source of information and we have participated with them over many years contributing to their papers and activities.
