GEO EXPRO is run by a small but dedicated team of people who all work together from different parts of the world to produce six magazines per year, in combination with publishing the magazine’s content online and on social media.
Our mission is to report on developments in the energy sector from a subsurface perspective, taking the role of observer and commentator on projects both in the oil and gas and renewable space. As such, we acknowledge the major importance oil and gas still plays with regards to energy security, whilst keeping a close eye on new developments in low-carbon subsurface solutions at the same time.
