3. Rig The machine used to drill a wellbore. In onshore operations, the rig includes virtually everything except living quarters. Major components of the rig include the mud tanks, the mud pumps, the derrick or mast, the drawworks, the rotary table or topdrive, the drillstring, the power generation equipment and auxiliary equipment Land rig DrillshipJackup Semisubmersible Submersible

5. Rotary Drill Bits Rotary drilling bits usually are classified according to their design as ”Fixed cutter bits(Drag bits)” and ”Rolling cutter bits”. Fixed cutter bits: PDC(Polycrystalline Diamond Compact) bit: A drilling tool that uses polycrystalline diamond compact (PDC) cutters to shear rock with a continuous scraping motion. These cutters are synthetic diamond disks about 1/8-in. thick and about 1/2 to 1 in. in diameter. PDC bits are effective at drilling shale formations, especially when used in combination with oil-base muds.

6. Rolling cutter bits (Roller-cone bits): A tool designed to crush rock efficiently while incurring a minimal amount of wear on the cutting surfaces. As the drillstring is rotated, the bit cones roll along the bottom of the hole in a circle. As they roll, new teeth come in contact with the bottom of the hole, crushing the rock immediately below and around the bit tooth. As the cone rolls, the tooth then lifts off the bottom of the hole and a high-velocity fluid jet strikes the crushed rock chips to remove them from the bottom of the hole and up the annulus. There are to types of roller-cone bits: Steel insert bits: Application for soft formations Steel insert bits: Application for soft formations

7. Drill Pipe Drill pipe is a tubular steel conduit fitted with special threaded ends called tool joints. The drillpipe connects the rig surface equipment with the bottomhole assembly and the bit, both to pump drilling fluid to the bit and to be able to raise, lower and rotate the bottomhole assembly and bit.

8.  Model: Tubing Pipes Type API 5CT Tubing : FIG.1-2 Tubing  Model: Casing Pipe Type: API 5CT Casing FIG 1.1 Casing Pipe OCTG ： Oil Country Tubular Goods (Seamless steel pipes) OCTG (80-85% of Oilfield Products)  Casing – used as a retainer wall for oil and gas wells  Production Tubing – transports oil and gas from wells to the surface  Couplings – connections used to join individual sections of casing and tubing together  Custom Finishing – premium threading, heat treating, upsetting, storage & inspection  Line Pipe (15-20% of Oilfield Products) Used in the gathering and transmission of oil and natural gas from the wellhead to larger transmission lines and refineries.

9. Stand pipe: A rigid metal conduit that provides the high-pressure pathway for drilling mud to travel approximately one-third of the way up the derrick, where it connects to a flexible high-pressure hose (kelly hose). Many large rigs are fitted with dual standpipes so that downtime is kept to a minimum if one standpipe requires repair. Swivel: A mechanical device that must simultaneously suspend the weight of the drillstring, provide for rotation of the drillstring beneath it while keeping the upper portion stationary, and permit high-volume flow of high- pressure drilling mud from the fixed portion to the rotating portion without leaking.

10. Drill Collar A component of a drillstring that provides weight on bit for drilling. Gravity acts on the large mass of the collars to provide the downward force needed for the bits to efficiently break rock. Type: API 7K Drill Collar
