Health, safety and environment (HSE) are of major concern in any industry. However, the history of the oil and gas industry, in addition to the inherent difficulties and dangers in exploration and production (E & P) activities, make it much more susceptible to questions raised by different affected parties like local authorities and environmentalists.
