Our Team

The Crogga management team has very broad international experience in the oil & gas industry and has worked on some of the largest and most complex oil and gas projects around the world.

Our management team are all Manx professionals, either current residents of the Island or have strong and enduring family connections with the Isle of Man.

Diccen Sargent: “The Isle of Man is our home, we live and work here. We are committed to the development of our natural gas to power electricity generation, boost our economy while protecting our environment and play a vital role in the transition to a zero carbon future.”

Diccen Sargent

Chief Executive Officer

Diccen is one of the founding members of Crogga and has been involved with the project since 2015. Diccen runs his own Manx-based consultancy company City Port Oil and Gas Services (CPOGS). He was involved in the initial stakeholder studies and conceptual engineering studies that confirmed the feasibility and commercial viability of an Isle of Man tie-back for Block 112/25 (the ‘Crogga Field’).

Diccen is managing director of CPOGS, a specialist consultancy working in the management of major accident risk for oil company service providers. Diccen has worked in the oil and gas sector for more than 28 years.

He was a member of the Total E&P senior management team for the Angolan ‘Dalia Field’ development (2000-2006). The Dalia development was a $4bn project commissioned by Total to develop a very deep-water oil and gas field off the west coast of Africa. This was one of the most complex operations completed this century involving cutting edge technologies. Diccen has also recently worked as an independent consultant to Septa Energy in Nigeria. This involved the design and construction of a project that was very similar in size to the proposed Crogga project.

Juan Cottier

Sub-surface Director

Juan has worked on the Crogga project since 2013 leading the geological, geophysical and reservoir engineering sub-surface studies to evaluate the natural gas potential of the Isle of Man in general and Block 112/25 (the ‘Crogga Field’) in particular.

Juan has an extremely long family presence on the Isle of Man and was himself educated on the island, studying geology at both Castle Rushen High School and St Ninian’s High School. Juan has been involved with the 112/25 gas discovery since 1992, when he wrote his Master’s thesis at the University of London on the hydrocarbon potential of the Isle of Man.

Juan has worked in the international oil and gas industry for more than 26 years. Firstly, 5 years with Talisman Energy on mature oil and gas fields in the North Sea. Secondly, 5 years with Canadian Natural Resources discovering new and redeveloping old oil fields in the Ivory Coast. Thirdly, 6 years with a specialist geological service company describing oil and gas reservoirs and quantifying hydrocarbon reserves worldwide. Fourthly, 3 years with Wintershall bringing new oil fields into production in Norway. And finally, 7 years as an independent geological advisor based on the Isle of Man.

Many of the geological and technical elements that Juan has encountered on a daily basis are pertinent to the Crogga project, with the key tasks being the understanding and characterisation of the reservoir, the planning of wells, and the safe and efficient operations which lead to producing natural gas for energy.
