Solution mining is one way producers can mine potash deep below the earth’s surface. Cooling ponds can become contaminated in the extraction process, which can result in the production of hydrogen sulfide - a dangerous and highly destructive chemical. Learn how researchers are finding ways to control it.

Unoccupied Aerial Vehicles (UAVs or drones) are also becoming a tool of interest for upstream oil and gas producers. A methane gas detection UAV is capable of spotting small, isolated gas leaks at ground level from up to 30 meters in the air — a feat that’s not quite as easy as it sounds.
