Drilling For Oil Offshore How It Works Everand Offshore drilling involves not just dealing with highly flammable oil and gas, with the added danger of this being pumped out at exceptionally high pressures, but also extreme wind and sea conditions. when danger strikes, support is often miles away by helicopter or ship and despite the high levels of training and increasingly safe equipment.
