How a offshore drilling rig works

These platforms can take the form of either floating semisubmersible platforms or drill ships. The basic idea behind their design is that, once the well has been drilled, much of the production equipment can be mounted on the seafloor and the petroleum pumped to the surface facilities through flexible risers.. . This platform is essentially a king-sized version of the Sea Star platform, except the tension legs extend from the ocean floor to the platform itself. It experiences more horizontal motion and a certain degree of vertical motion, but it allows oil companies to drill at. . Finally, if you absolutely need to drill a hole at a depth of 10,000 feet (3,048 meters), then the spar platform is the oil rig for you. With this design, the drilling platform sits atop a giant, hollow cylindrical hull. The other end of the cylinder descends around. . This approach takes the idea of mounting the wellhead on the seafloor and applies it to even greater depths — 7,000 feet (2,134 meters) or more. Once the well has been drilled by a. . Deep-sea waters reach nearly freezing temperatures, contain pressures great enough to crack iron casings and are subject to rough, deep-sea currents. Engineers have to design equipment that can stand up to the pressure, while also preventing boiling oil. [pdf]

There are many colourful and simplified terms used to describe the drilling process and parts of a rig. The following are a list of some of the animal bearing terms describing various components of a rig and drilling activity: Wildcat – A well drilled where no oil and gas production currently exists.

What is a Kelly drill rig?

A kelly is the first joint of the drill string used in conventional rotary drilling rigs, and fits into the rotary table and helps to rotate the drill string and bit downhole. Are there others terms you would like to find the definition for? Check out Schlumberger’s The Oilfield Glossary for more lingo in the oilpatch!

What is a drilling rig doghouse?

Once the bit has been replaced, the derrickhand helps to guide the drill string and new bit back into the hole. Doghouse – On a drilling rig, this is the structure located beside the rig floor that houses the computer equipment to monitor and record drilling activity. The doghouse is also where drilling crew members meet for safety meetings.

What is a dog collar in a drill rig?

Dog collar - A clamp placed tightly around a drill collar that is suspended in the rotary table by drill collar slips. Dog House —Where the driller controlling the rig floor works. Dogleg - A particularly crooked place in a wellbore, a dogleg commonly refers to a section of the hole that changes direction faster than desired

What is a mousehole in a drilling rig?

Mousehole – This is a hole located under a drilling rig floor and is drilled to the side of a wellbore to hold the next segment of pipe the drilling crew will add to the drill string. When the joint of pipe is added to the drill string, another section of pipe is readied and slipped into the mousehole to await its turn.

What is a Rathole in a drilling rig?

Rathole – This is the hole in the rig floor that acts as the storage place for the kelly when it isn’t in use. A kelly is the first joint of the drill string used in conventional rotary drilling rigs, and fits into the rotary table and helps to rotate the drill string and bit downhole.
