Drilling is an operation aimed at exploring the subsoil, on land or at sea, to identify oil and natural gas deposits. This soil sounding consists of detecting the presence or not of liquid or gaseous hydrocarbons, their nature, as well as the volume of the reserves, in order to develop there exploitation operations of the detected deposits, in other words the putting into production of the field, as well as well maintenance and optimization.

The location of a borehole is decided following geological and geophysical studies. These studies make it possible to get an idea of the constitution of the subsoil and the possibilities of deposits, but they cannot detect with certainty the presence of hydrocarbons. Only drilling will be able to confirm the hypotheses made and highlight the nature of the fluids contained in the rocks.

Drilling objectives

The drilling operation consists of:

  • develop the drilling and casing program for the well: specify the depth, the target objective, its characteristics of the different drilling phases,
  • design and build wells: working in close collaboration with the geological, reservoir and production engineers, the drillers are responsible for implementing the appropriate technical means in the field in complete safety for digging the wells,
  • drive a drill string into the subsoil, using a derrick, by injecting a special mud, called “drilling mud”*,
  • control the density of the drilling mud during the drilling operation: the preparation of the density of the drilling mud is a strategic step and its density must be controlled during the drilling operation to ensure its smooth running. A specialist must constantly monitor the characteristics of the mud and be reactive to modify its composition as quickly as possible in the event of a problem.

* Drilling mud is used to bring rock fragments and gas samples to the surface to determine the location of a potential oil or gas deposit. The drilling can go from a few hundred meters up to 9 km. If the drilling mud is too heavy, it may enter the reservoirs. If it is too light, on the contrary, it can cause an uncontrollable and dangerous eruption, both for the teams and for the environment.

Drilling and deposit exploitation professions

The drilling and exploitation of deposits call upon various categories of trades:

  • Geologist Engineer
  • Drilling Engineer
  • Reservoir Engineer
  • Production Engineer
  • Drilling Supervisor
  • Driller
  • Chief Rig Mechanic
