Before beginning the study of the BOP, it is necessary to understand the rudiments of offshore petroleum drilling. This is why I tried to make a summary of it in order to more precisely define the terms used in the continuation. Oil results mainly from organic matter trapped in geological layers and subjected to strong pressures and temperatures, a weak concentration of oxygen and hydrogen sulphide. Geology makes it possible to locate the layers likely to contain some by methods of acoustic analysis of the ground. The exploration drilling will then make it possible to confirm the forecasts and to determine profitability of it. It will be followed by drillings of exploitation which will make it possible to extract the resources from them. When one drills through geological layers, one meets there all kinds of materials of variable hardness but also fluids and gases. The problem of drilling mainly consists in using tools adapted to the ground, to maintain th
