Jon Gutmanis

Chief Geologist 

Jons love of geology began with fieldwork in SW England as a teenager and he is still amazed at how a hobby somehow   metamorphosed into a career. He leads our Reservoir Geology group and, as a structural geologist, is pleased to be learning all about rudist corals or carbonate diagenesis from others in the group. Teaching field geology courses in the Catalonian Pyrenees is another source of delight!

Lucy Cotton
