Drilling Engineering I Quiz

A well drilled in an area with little to no geological information, hoping to find oil or gas.

A well drilled to determine if an area has hydrocarbons and to gather geological data.

A well in a known oil field used for extracting oil or gas.

A well drilled between existing producing wells to increase production.

A well used to inject fluids into the ground to increase pressure or displace oil.

A well used for safely injecting waste fluids into the ground.

A well with a depth less than 2000 meters.

A well with a depth between 3500 and 5000 meters.

A method of drilling wells using a bit suspended by a rope, raised and lowered by a walking beam to pound the well down.

A wooden or metal beam that pivots up and down, raising and lowering the drilling bit in cable tool drilling.

A steel rod with a chisel point, used to crush rock in cable tool drilling.

Large diameter pipe run into the well to prevent water from filling and the sides from caving in.

The process of raising and lowering equipment (drillstring, casing, tools) in and out of the well as efficiently as possible.

The part of the rotary rig that causes the drillstring and bit to rotate.

A long assemblage of pipes connected to form a rigid column that is rotated to drill the well; part of a rotary rig.

A tall, strong frame that supports the hoisting equipment in a rotary rig.

The circulating process in drilling controls subsurface pressure, removes cuttings, and cools/lubricates the drill stem and bit.

The power system of a drilling rig powers the rotary table, drawworks, mud pumps, lighting, and hydraulic systems.

A machine used to create holes, like water/oil wells.They can be large structures or small, manually moved.

A drilling team comprises the contractor's staff, operators like Petronas, service companies (like Halliburton), and supply companies.

Drilling engineers prepare drilling programs (including cost estimates) and work with geologists, mud engineers, and service companies.

Well site prep involves surveying, site clearing, digging access roads/pits, and providing water.

Drilling contracts include daily rate, turnkey, footage rate, and incentive-based contracts.

A drilling rig designed for drilling relatively shallow wells, typically from 3000 to 5000 feet (1000 to 1500 meters) deep.

A drilling rig that can drill to a greater depth than a light duty rig, ranging from 4000 to 10000 feet (1200 to 3000 meters).

A rig built for drilling deep wells, reaching depths from 12000 to 16000 feet (3500 to 5000 meters).

The most powerful type of land drilling rig, capable of drilling to the greatest depths, around 18000 to 25000 feet (5500 to 7500 meters).

The foundation of the rig, located directly over the well. It provides a working platform called the 'rig floor' and space for equipment.

The working platform on top of the substructure, where the drilling crew works.

A space typically under the rig floor, providing room for equipment like high-pressure valves and the blowout preventer.

The drawworks is a hoisting mechanism responsible for lifting and lowering the drillstring (including drill pipes, drill collars, and the drill bit) into and out of the borehole.

The traveling block is a pulley system that connects the drillstring to the hoisting cable (drill line) and suspends the load above the wellbore.

The drawworks reels in and lets out the drill line, which is attached to the traveling block, thereby lifting or lowering the drillstring.

The crown block is a fixed pulley system located at the top of the derrick, guiding the drill line between the traveling block and the drawworks.

The hook is attached to the traveling block and suspends the swivel and Kelly (which connects the drillstring to the rotary table). This entire assembly is raised and lowered by the drawworks.

The brake system allows the driller to safely control the weight of the drillstring (thousands of pounds) during lifting and lowering operations.

The gear system allows the driller to adjust the speed of lifting and lowering the drillstring, enabling precise control.

A mouse hole connection is a specialized type of connection used in drilling to join sections of drill pipe.

The relationship where decreasing the force required to lift a weight increases the distance the rope needs to be pulled. For example, halving the required force doubles the rope distance.

The side of a derrick opposite the drawworks, kept clear for pipe handling.

The layout of a derrick, indicating the location of the drawworks, dead line, and V-gate.

The drawworks is usually situated between two legs of a conventional derrick.

The dead line is anchored close to one of the remaining legs, ensuring space for the V-gate.
