,This well starts off vertical, but after reaching the target, Extended reach well
the driller will kick off the well to eventually go horizontal
for a long distance
This is the place where the Kelly is stored when a trip is Rat hole
being made
The hoisting system of a drilling rig: Applies weight on bit and lifts/lowers the drill string
Which of these is NOT a reason for drilling deviated wells? It makes drilling the well easier overall
Reasons:
To touch more of the reservoir
To enhance the ultimate recovery of the well
To save on number of platforms used offshore
PDC means, in drill bit terminology, Polycrystalline Diamond Compact (Cutter) bit
Normal earth or lithostatic pressure gradient is 100 psi/100 ft
about***********
The process in which the drill bit is changed by pulling the Making a trip
drillstring from the well is called:
Which of these is NOT a common problem encountered Geothermal cooling
while drilling a well?
Common problems:
Lost circulation
Fishing
Stuck pipe
Directional or deviation drilling happens when a vertical False
well is a little crooked (unintentionally) because of
problems in the reservoir.
The process in which a piece of drillpipe is added to the Making a connection
drillstring to make it longer
The power system of a drilling rig: Provides the energy to operate the rig, often consisting of diesel engines that run
electric generators
Which of the following is a purpose served by drilling mud? All of the choices.
Controlling pressures in the well thereby preventing blowouts.
Removing cuttings from the bottom of a well during drilling.
Cleaning cuttings from a drill bit as it turns.
Cooling and lubricating the drill bit.
This piece of equipment is gripped and turned by the Kelly
rotary table and is used to turn all the pipe below it to drill
the hole
, Torque is applied to the drill bit by the rotating system. True
Tricone bits: Have three cone-shaped rollers with teeth that are designed to flake or crush rock
This piece of equipment allows the drillstring that is Swivel
attached below it to rotate on bearings while the weight of
the pipe is suspended from the derrick or mast
Normal geothermal gradient in a sedimentary basin is 1.4°F/100 ft
The two main methods of controlling a kick are the driller's True
method and the wait-and-weigh method
This hole is a vertical well that is drilled straight down with Straight hole
no unintended deviations
Normal fluid pressure gradient is about 45 psi/100 ft
This well starts off vertical, but after reaching the target, Deviated well
the driller will kick off the well at a certain angle.
The rotating system of a drilling rig: Supplies torque to turn the drill bit
Which list below lists bit type in order of softest to hardest Milled-teeth tricone, insert tricone, PDC
rock application?
Which one of these tools is NOT used in a fishing job? Rotator cuff
Used in a fishing job:
spear
washpipe
overshot
This hole is a vertical well that is drilled straight down with Crooked hole
unintended deviations
This piece of equipment is a steel wedge with handles and Slips
is placed in the rotary table bowl to hold the pipe with teeth
and prevent the drillpipe from falling down the hole
Normal geothermal gradient for the earth is 2°F/100 ft
