Drilling String ComponentsDrilling String Components
3. Stabilizers: of a blade type
construction. Drilling fluid can pass
freely between the blades while the
outer edge of the blades contacts the
wall of the hole and holds the drill
collars firmly centered in the hole.
They do exactly as their name
implies, they provide stability to the
bit and collars.
Drilling String ComponentsDrilling String Components
• Reamers: These usually have the same
diameter as the bit and are run a little distance
above it
• Under-reamers: Used opening out a hole below
a restriction such as imposed by the blow-out
preventer assembly.
• Hole Openers: Used for drilling large diameter
holes. They have replaceable cutters and serve
the same function as an underreamer except
they are not collapsible and can only be used
when there is no restriction smaller than the hole
size they drill.
Drilling String ComponentsDrilling String Components
Rotary Bits
1. Drag Bits:- no moving
parts but drill by the
shovelling action of their
blade on the formation.
2. Roller Bits:- have
rotating cones.
Three cone bits (Tri-Cone)
are the most widely used in
the oil field.
Drilling String ComponentsDrilling String Components
3. Diamond Bits:- These
are designed to drill by the
scraping action of
diamonds set in a steel
matrix. This type of bits is
normally used in hard
formations where long bit
life and the subsequent
reduction in trip time are
desirable.

List of Common Drilling Terms
Abandon : To cease producing oil or gas from a well.
Abnormal Pressure :Pressure exerted by a formation exceeding normal
pressure for any given depth.
Acidize :To inject Hcl into a calcareous formation under
pressure, that causes, enlargement of fissures and
improvement of permeability characteristics.
Annular BOP :A large valve installed above the ram preventers.
Annular Space :The space between drill string and casing or open
hole.
API :American petroleum Institute; founded in 1920,
this organisation aims for standardisation in the oil
field.
Back off :To unscrew one threaded section from another as
with pipe.
Barite :Ba S04, a mineral used to weight up drilling fluid.
Barrel :42 US. Gallon = 158.97 litres 1m3 = 6.2897 bbls.
Basket Sub :Fishing accessory run above a bit or mill to
recover small pieces of junk.
Bit breaker :Device for breaking out the bit from the string.
Blow-out Preventer BOP’s :Equipment installed to prevent the uncontrolled
escape of gas oil or salt water from the well.
Breakout :To unscrew one section of pipe from another
generally during pulling of pipe. The tongs are used
in this operation.
Calibre Log :A record of the diameter of the wellbore
indicating washout or enlargements due to casings.
Cap a well :To control a blow-out by placing a very strong
valve on the well bore.
Casing shoe :A short heavy hollow cylindrical steel- concrete
section with a rounded bottom placed on the end of
the casing shoe. Also called a guide shoe.
Fish :An object left in the well that need be recovered.
Fracturing :A method to stimulate production from a poorly
permeable zone by pressuring open the fissures
jacking them open with beads or such like, then
releasing this pressure.
Gas cut mud :A drilling mud with entrained formation gas,
causing reduced weight.
Joint :A single length of drill pipe, casing or drill collar.
Kelly saver sub :A short sub placed between kelly and drill pipe to
save excessive wear on the kelly threads.
Kelly spinner :A pneumatically operated device mound on the top
of the kelly that turns the kelly. useful in making up
pipe.
Latch on :To attach the elevators to a section of pipe to pull
it, or run it, into hole.
Monkeyboard : A platform on derrick from which the derrickman
works while triping.
Mouse-hole :An opening in the rig floor, pipe lined, that singles
are placed in before making up.
Mudman :The mud engineer.
Nipple up :To assemble the BOP stack onto the well.
Perforate :To pierce the casing and cement for the purpose of
allowing formation fluids to enter the production
piping.
Pull out :To trip string out of the hole.
Rat hole :Either a line hole in the rig floor on that the kelly
is kept during trips, or a hole of smaller diameter
drilled at the bottom of the main hole.
Round trip :To trip out, then into the hole.
Run in :To trip pipe into the hole.
Sheave :A grooved pulley.
Sidetrack :To drill around a blocked well bore by kicking off
a new hole at an angle to the original.
Stuck pipe :Drill string, casing or tubing that has become
immovable in the hole.
Sub :A short length of pipe, threaded at each end, used
to adapt different pats of the drill string that
otherwise would not connect, or else to perform a
specialist function e.g. junk sub, kelly saver sub.
T.D. :Abbreviation of total depth - the end of the well.
Tight hole :Under gauge hole section through which it is
difficult to pull the drill string. Or a well about that
information is restricted.
Tongs :The large wrenches used for making up or
breaking out drill pipe.
Work Pipe :Moving the drill string up and down in the hole
whilst not rotating to prevent sticking.
Wiper trip :A short trip up into casing then back to bottom to
clean out the hole, to check for gauge, and to
reduce the danger of getting stuck.

  • 22. Drilling String ComponentsDrilling String Components 3. Stabilizers: of a blade type construction. Drilling fluid can pass freely between the blades while the outer edge of the blades contacts the wall of the hole and holds the drill collars firmly centered in the hole. They do exactly as their name implies, they provide stability to the bit and collars.
  • 23. Drilling String ComponentsDrilling String Components • Reamers: These usually have the same diameter as the bit and are run a little distance above it • Under-reamers: Used opening out a hole below a restriction such as imposed by the blow-out preventer assembly. • Hole Openers: Used for drilling large diameter holes. They have replaceable cutters and serve the same function as an underreamer except they are not collapsible and can only be used when there is no restriction smaller than the hole size they drill.
  • 24. Drilling String ComponentsDrilling String Components Rotary Bits 1. Drag Bits:- no moving parts but drill by the shovelling action of their blade on the formation. 2. Roller Bits:- have rotating cones. Three cone bits (Tri-Cone) are the most widely used in the oil field.

  • 32. List of Common Drilling Terms Abandon : To cease producing oil or gas from a well. Abnormal Pressure :Pressure exerted by a formation exceeding normal pressure for any given depth. Acidize :To inject Hcl into a calcareous formation under pressure, that causes, enlargement of fissures and improvement of permeability characteristics. Annular BOP :A large valve installed above the ram preventers. Annular Space :The space between drill string and casing or open hole. API :American petroleum Institute; founded in 1920, this organisation aims for standardisation in the oil field. Back off :To unscrew one threaded section from another as with pipe. Barite :Ba S04, a mineral used to weight up drilling fluid. Barrel :42 US. Gallon = 158.97 litres 1m3 = 6.2897 bbls. Basket Sub :Fishing accessory run above a bit or mill to recover small pieces of junk. Bit breaker :Device for breaking out the bit from the string. Blow-out Preventer BOP’s :Equipment installed to prevent the uncontrolled escape of gas oil or salt water from the well. Breakout :To unscrew one section of pipe from another generally during pulling of pipe. The tongs are used in this operation. Calibre Log :A record of the diameter of the wellbore indicating washout or enlargements due to casings. Cap a well :To control a blow-out by placing a very strong valve on the well bore. Casing shoe :A short heavy hollow cylindrical steel- concrete section with a rounded bottom placed on the end of the casing shoe. Also called a guide shoe. Fish :An object left in the well that need be recovered. Fracturing :A method to stimulate production from a poorly permeable zone by pressuring open the fissures jacking them open with beads or such like, then releasing this pressure. Gas cut mud :A drilling mud with entrained formation gas, causing reduced weight. Joint :A single length of drill pipe, casing or drill collar. Kelly saver sub :A short sub placed between kelly and drill pipe to save excessive wear on the kelly threads. Kelly spinner :A pneumatically operated device mound on the top of the kelly that turns the kelly. useful in making up pipe. Latch on :To attach the elevators to a section of pipe to pull it, or run it, into hole. Monkeyboard : A platform on derrick from which the derrickman works while triping. Mouse-hole :An opening in the rig floor, pipe lined, that singles are placed in before making up. Mudman :The mud engineer. Nipple up :To assemble the BOP stack onto the well. Perforate :To pierce the casing and cement for the purpose of allowing formation fluids to enter the production piping. Pull out :To trip string out of the hole. Rat hole :Either a line hole in the rig floor on that the kelly is kept during trips, or a hole of smaller diameter drilled at the bottom of the main hole. Round trip :To trip out, then into the hole. Run in :To trip pipe into the hole. Sheave :A grooved pulley. Sidetrack :To drill around a blocked well bore by kicking off a new hole at an angle to the original. Stuck pipe :Drill string, casing or tubing that has become immovable in the hole. Sub :A short length of pipe, threaded at each end, used to adapt different pats of the drill string that otherwise would not connect, or else to perform a specialist function e.g. junk sub, kelly saver sub. T.D. :Abbreviation of total depth - the end of the well. Tight hole :Under gauge hole section through which it is difficult to pull the drill string. Or a well about that information is restricted. Tongs :The large wrenches used for making up or breaking out drill pipe. Work Pipe :Moving the drill string up and down in the hole whilst not rotating to prevent sticking. Wiper trip :A short trip up into casing then back to bottom to clean out the hole, to check for gauge, and to reduce the danger of getting stuck. Common Rig TermsCommon Rig Terms
