Boreholes are made to recover oil and gas using a machine known as a drilling rig.

They can be mobile equipment mounted on trucks, tracks or trailers, or more permanent land-‐ or marine-‐based structures (such as oil plagorms, commonly called ‘‘oﬀshore oil

rigs’’). The term ‘‘rig’’ refers to the complex of equipment that is used to penetrate the surface of the Earth’s crust.

(14)

Larger, more ﬁxed installaVons are capable of drilling through thousands of meters of the

Earth’s crust. Large ‘‘mud pumps’’ circulate drilling mud (slurry) through the drill bit and the casing, for cooling and removing the

‘‘cuings’’ while a well is being drilled. Hoists

in the rig can lij hundreds of tons of pipe.

(15)

Other equipment can force acid or sand into reservoirs to facilitate extracVon of the oil or mineral sample. Marine rigs may operate many hundreds of miles or kilometers oﬀshore with infrequent crew rotaVon

The Mud Circulation System

During drilling, mud is circulated, down the drill string through the bit and back up along the annulus. At surface, the mud is passed over the shale shaker to

remove cuttings.

Other equipment such as hydrocyclones, centrifuges and settling tanks may be

required to meet the optimum solids level.

Learning Outcome

Ø Explain the various components of an oil/ gas well drilling rig and the respecVve drilling operaVons. Ø Develop a methodology for the drill-‐ string and

casing design

Ø Develop a strategy for a well control based on rheological models and drilling hydraulics
