Once the whole equipment is at drilling site, the staff will set the drilling rig up. There are some major parts of a land oil rig:

Drilling Parts

Hoisting system – used for lifting heavy loads; consists of a mechanical winch with a large steel cable spool, a block-and-tackle pulley and a receiving storage reel for the cable

Swivel (Tong) – large handle that holds the weight of the drill string; allows the string to rotate and makes a pressure-tight seal on the hole

Turntable or rotary table – drives the rotating motion using power from electric motors

Drilling Pipe – consists of drill pipe (connected sections of about 30 feet (10 meters) and drill Collars (larger diameter, heavier pipe that fits around the drill pipe and places weight on the drill bit)

Drill bit(s) – end of the drill that actually cuts up the rock; comes in many shapes and materials (tungsten carbide steel, diamond) that are specialized for various drilling tasks and rock formations

Casing – large-diameter concrete pipe that lines the drill hole, prevents the hole from collapsing, and allows drilling mud to circulate

Blowout preventer – high-pressure valves (located under the land rig or on the sea floor) that seal the high-pressure drill lines and relieve pressure when necessary to prevent a blowout (uncontrolled gush of gas or oil to the surface, often associated with fire)

Circulation system

pumps drilling mud (mixture of water, clay, weighting material and chemicals, used to lift rock cuttings from the drill bit to the surface) under pressure through the kelly, rotary table, drill pipes and drill collars

Pump – sucks mud from the mud pits and pumps it to the drilling apparatus

Pipes and hoses – connects pump to drilling apparatus

Mud-return line – returns mud from the hole

GN shale shaker – sieve large particle and solids from drilling fluids which 100% separate the cutting

GN Mud cleaner- Second step is after the shale shaker, which is including 10 inch desander and 4 inch desilter. Mud cleaner can handle from 350 GPM to 1500 GPM drilling fluids

GN Decanter Centrifuge-Cutting points reach to 2~10 microns, effectively separate the fine partilce

GN Screw Conveyer(Auger) – conveys cuttings from GN Solids Control unit to the reserve pit
reserve pit – collects rock cuttings separated from the mud

GN Mixing and Recycle Tank – where drilling mud is mixed and recycled

GN Jet Mud Mixer – where new mud is mixed and then sent to the mud tank

For drilling site circulation system, you could consult with GN for a better option.
