- 2. Introduction to MSME •MSME is Ministry of Micro, Small & Medium Enterprises • The Micro, Small and Medium Enterprises (MSME) sector has emerged as a vibrant and dynamic sector of the Indian economy. MSMEs play crucial role in providing large employment opportunities at comparatively lower cost than large industries. • In mSME Nagour, we got the opportunity of training from the experts team of MIT Pune.

- 10. Rig engines orprime mover • Modern oil rigs use internal combustion engines as their main power plants (i.e. Diesel engines) • Number and size of engines required depend on the size and rating of the rig • For shallow drilling(<5000ft), two engines are used to develop a power of 500-1000 hp • Deep water drilling( deeper than 10000ft)uses 3-4 engines which are capable of developing 3000 hp • Transmission of the developed power to various parts of the rig is achieved either mechanically or electrically
- 11. Derrick & Sub-structure •Derrick is a four-sided structure of sufficient height and strength to allow the hoisting (lowering and raising) of equipment in and out of the well • It also provides a working place for the derrick man during tripping operations • The substructure provides support for the derrick, draw-works and drill string
- 12. Hoisting System Hoisting Mechanism Enablingheavy loads to be raised or lowered by means of wire rope Helps in tripping in and out Components are: • Drum • Crown block • Travelling block • Drilling line

- 14. Rotary Equipment • Rotarydrilling Equipment include: • Rotary table • Master bushing • Kelly • Kelly bushing • Swivel • Drill stem • Functions of rotary table is to transfer rotary motion through a master bushing to the Kelly to drill pipe and eventually to the drill bit • Power required for the rotation of the table is transmitted from the main engines through a chain drive from the compound as in mechanical rigs • Or the rotary table is independently powered through a cable connected to a motor attached to the rotary table
- 15. Rotary Equipment • Rotarydrilling Equipment include: • Rotary table • Master bushing • Kelly • Kelly bushing • Swivel • Drill stem • Besides transferring rotation to the Kelly, the master bushing also acts as a seat for slips • Slips are wedge-shaped device, lined with tooth-like gripping elements. They are needed to hold the drill string suspended in the hole when adding or breaking joints of drillpipe or drill collar
- 16. Rotary Equipment • Rotarydrilling Equipment include: • Rotary table • Master bushing • Kelly • Kelly bushing • Swivel • Drill stem • Kelly has a hexagonal or a square base • Main function is to transfer motion to the drill pipe • Also serves a medium for transporting mud down to the drill pipes and to the bits • During tripping in or out, Kelly completely rest in a side hole called rathole Kelly Kelly bushing Kelly Bushing Master Bushing Dependency on friction Independent of friction
- 17. Rotary Equipment • Rotarydrilling Equipment include: • Rotary table • Master bushing • Kelly • Kelly bushing • SWIVEL • Drill stem • Installed above the Kelly • Main function is to prevent the rotary motion of the Kelly from being transferred to drilling line • Swivel has a bail which fits inside a hook at the end of travelling block • The swivel also allows mud to be pumped through the Kelly through a side attachment, described as ‘gooseneck’ Bail Goose neck
- 18. Rotary Equipment • Rotarydrilling Equipment include: • Rotary table • Master bushing • Kelly • Kelly bushing • Swivel • DRILL STEM • Consists of: • Drill pipe • Drill collars • Accessories • Drill bit • Drill pipe serves as a medium for the transmission of rotary motion to the bit and also acts as a passage for mud. • Drill collars are heavy-duty pipes with large outside diameters. They are used primarily to put weight on the bit during drilling operations • Accessories include: • Heavy-walled drill pipes • Stabilisers • Shock subs • The drill bit is the main component of the drill string and is used to cut the rock for the purpose of making hole Drill pipe Drill bit Drill collar
- 19. Drill String Drill Stringis made from 3 Basic Components • Drill Bit • Drill Pipe • Drill Coller Drill Pipe Drill Bit Drill Coller

- 21. Mud Pumps • Pistonreciprocating inside a cylinder • Used to circulate huge quantities of mud (300-700 gpm) down thousands of feet of drill pipe through small nozzles at the drill bit and finally up the hole to arrive at surface again. • Types: • Duplex pumps • Triplex pumps • Variations in volume and pressure can be obtained by changing the inside diameters of the cylinder through the use of liners or changing piston sizes MUD
- 22. BOP(BlowOut Preventer) • BOPare valves that can be closed any time a well kick is detected • A well kick is an unwanted flow of formation fluids into the well bore hole which may(if not controlled) develop into a blowout. BOP Annular preventers Pipe Rams Standard Variable Blind and shear rams Blind Shear
