Oil Rig

QuestionAnswer
Derrick Supports the drilling equipment and hoisting system
Drill Floor Working area where drill pipe is connected and operations occur
Drawworks Hoists the drill string and provides drilling power
Crane Lifts equipment and supplies
Mud system Circulates drilling fluid to cool the bit and carry cuttings
Helipad Transport for crew and emergency use
BOP stack Blowout preventer to prevent uncontrolled release of pressure
Drill string and drill bit Drill pipe transports power to the bit, which drills into the seabed
What is an oil rig A giant machine for drilling a controlled hole through the ocean floor and into underground rock formations
Top drive A powerful motor near the top of the drill string that rotates it
Drilling mud Fluid that cools the drill bit and carries rock cuttings back into the surface. Also provides hydrostatic pressure
Kick Oil, gas, or formation fluid can enter the wall
Cement Used for between the casing and the surrounding rock. Holds casing in place and helps prevent fluids from moving between geological formations.
Well logging Gamma Ray, resistivity, porosity
How to evaluate rock formation for oil Rock cuttings, formation pressure, mud properties, geological data, porosity...
Oil reservoir Typically porous rock containing fluids like oil, natural gas, water. The rock needs sufficient permeability for oil to move through the reservoir.
How does oil get to the surface Reservoir pressure may be enough to push fluids upward (Natural flow). or through gas lift.
Gas lift Gas is injected into the production tubing, reducing the effective density of the fluid column and helping production flow upward.
