TGS chief executive Kristian Johansen is surprisingly relaxed for an oilman weathering his first major downturn, but with perspective gained outside the oil industry and a financially-­conservative company culture, he believes the seismic player was built for times like these.

Johansen joined TGS as chief financial officer in 2010 after working in similar roles for a pair of large publicly-traded companies in his native Norway, as well as five years of investment banking in London, but with only a year of experience in the oil and gas sector.
