Purpose: To control a well by pumping heavy drilling fluid into the wellbore. Description: The kill line is a high-pressure pipe leading from an outlet near the rig floor to the high-pressure side of the blowout preventers.

Purpose: To make and break connections of drill pipe. Description: The iron roughneck is an automated system that handles and manipulates the drill string on an oil rig, reducing the risk of manual operations.

Purpose: To move drill pipes to and from the drill floor. Description: A catwalk is an elevated platform that serves as a path for moving drill pipes and other equipment to the rig floor safely.

Purpose: To impart rotational power to the drill string during drilling operations. Description: The rotary table is a mechanical device on a drilling rig that provides clockwise rotational force to the drill string.

Purpose: To control well pressure during offshore drilling. Description: Subsea BOPs are blowout preventers specifically designed for underwater installations on offshore drilling rigs.

Purpose: To transfer rotary motion to the drill string. Description: The Kelly drive is a square or hexagonal-shaped pipe that transmits torque and rotation from the rotary table to the drill string.

Purpose: To remove sand particles from drilling fluid. Description: A desander is a centrifugal device for removing sand from drilling fluid to prevent grinding and wear on the drill bit.

Purpose: To remove fine silt-sized particles from drilling fluid. Description: A desilter is similar to a desander but is designed to remove smaller solids (silt-sized particles) from the drilling fluid.

Purpose: To provide a movable set of pulleys to lift and lower the drill string. Description: The travelling block moves up and down the derrick in conjunction with the crown block to multiply the force exerted by the drawworks.

Purpose: To temporarily hold the next stand of drill pipe. Description: The mousehole is a shallow bore beneath the rig floor, typically containing a joint of drill pipe which will be used next in the drilling operations.

Purpose: To allow rotation of the drill string while maintaining a seal on the drilling fluid. Description: The swivel hangs from the hook of the travelling block and connects to the top of the kelly drive, allowing the drill string to rotate without twisting the drilling line.

Purpose: To support the drilling apparatus and lifting system. Description: A derrick is a tall tower that supports the drilling equipment, including the hoisting system used to raise and lower the drill string.

Purpose: To cut through and break the rock forming the oil well. Description: A drill bit is a tool attached to the end of the drill string that breaks apart, cuts, or crushes the rock formations when drilling a wellbore.

Purpose: To separate drill cuttings from drilling fluid. Description: A shale shaker is a vibrating screen used to remove cuttings from the circulating drilling fluid, allowing it to be reused.

Purpose: To control well pressure by regulating the flow of fluids. Description: The choke manifold is an arrangement of valves and chokes that can be used to lower the pressure from the wellhead.

Purpose: To rotate the drill string during the drilling process. Description: A top drive is a motor that is suspended from the derrick of a drilling rig, providing rotational force to the drill string, eliminating the need for a rotary table.

Purpose: To store the drill pipes on the rig. Description: Pipe racks are structures designed to hold and organize horizontal drilling pipes when they are not in use.

Purpose: To safely vent gas entrained in drilling fluids. Description: The mud gas separator is a device used to separate and vent large pockets of gas that can accumulate in drilling fluid.

Purpose: To transmit drilling fluid to the drill bit and facilitate the drilling process. Description: The drill string is a column, or a series of drill pipes, that transmits the rotational force from the drill rig to the drill bit.

Purpose: To lift and lower the drill string and casing into and out of the wellbore. Description: The drawworks is a large winch that spools off or takes in the drilling line and thus raises or lowers the drill string and casing.

Purpose: To lubricate the drill bit, carry cuttings to the surface, and maintain hydrostatic pressure. Description: Drilling fluid, or 'drilling mud', is a mixture used to aid the drilling of boreholes into the earth.

Purpose: To stabilize and protect the wellbore. Description: Casing is large diameter pipe that is assembled and inserted into a recently drilled section of a well and is typically held in place with cement.

Purpose: To provide a vertical conduit for drilling fluid. Description: The standpipe is a rigid metal conduit that provides a high-pressure pathway for drilling fluid to travel from the mud pumps to the rotary hose.

Purpose: To deliver drilling fluid from the standpipe to the swivel. Description: The rotary hose is a flexible, high-pressure hose that connects the standpipe to the swivel, allowing for fluid circulation while facilitating movement of the derrick.

Purpose: To prevent uncontrolled release of crude oil or natural gas from a well. Description: BOP is a large, specialized valve used to seal, control and monitor oil and gas wells to prevent blowouts.

Purpose: To monitor the overall volume of drilling fluid in the system. Description: The pit volume totalizer (PVT) is an electronic device that measures and displays the total volume of drilling fluid in the tanks, alerting the crew to any significant changes that could indicate well control issues.

Purpose: To circulate drilling fluid under high pressure down the drill string and back up the annulus. Description: Mud Pump is a reciprocating piston/plunger device designed to pump drilling mud (composed of water, oil, or synthetic-based fluids) to lubricate the drill bit.

Purpose: To monitor fluid level when pulling out or running into the hole with drill string. Description: A trip tank is a small tank with a known volume that is used to detect a change in mud volume to identify kicks or lost circulation when tripping pipe.

Purpose: To store drill collars near the drill floor. Description: A rathole is a hole on the rig floor into which part of the drill string is placed when the drill string is being assembled or disassembled.
