Natural Gas Leak in the British North Sea

Natural gas drilling platforms were evacuated in the British North Sea because of a gas leak that could be easily ignited. Methane as well as hydrogen sulfide gasses are present in the potentially explosive mix, as well as leaking liquid gas into the water. A well that is primarily natural gas would dissipate into the air, however, this well contains what is termed “sour gas” which contains high concentrations of hydrogen sulfide gas. The leak is proving to be difficult to cap, because the distance required to keep the crew safe is not conducive for options such as drilling relief wells. Though chemical dispersants have not been deemed necessary for the amount of liquid gas in the sea, every precaution is being taken, as to the safety of all involved. Levels of hydrogen sulfide and methane gasses will have to be measured constantly as the capping and recovery process of this disaster begins.
