Rig Equipment
What is the max torque (supposedly) for the HexGrip & what is the max tension for the hoists on the rig floor?
120,000 ft-lbs
6,400 lbs
What type of drill bits do we use & what does MWD stand for?
PDC
Measure While Drilling
What is a kick & what is a blowout?
An unwanted influx of formation fluids into the wellbore
An uncontrolled release of wellbore fluids at surface
What is the BOP rated for (pressure) & what size is it?
10,000 psi
13-5/8"
What does PSMS stand for & what is the goal of PSMS?
Personnel Safety Management System
Eliminate LAI's (Life altering injuries)
What pieces of equipment do we need to change when we change drill pipe size & thread type (name 4)?
Saver Sub
FOSV (TIW)
Dart Valve
Slips
Elevators
What are our two methods of directional control?
RSS
Conventional
What is the definition of porosity & permeability?
Porosity - The measure of the void spaces within a rock
Permeability - The ability for fluids to flow through a rock
What is the annular rated for, what sizes can it close on & what is the annular element made of?
5,000 psi - 0 to 13-5/8"
Rubber elastomer
What does V&V stand for & what is it's purpose?
Verify & Validate
To ensure safeguards are in place & effective
What kind of mud pumps do we have (make & model) & what is their max horsepower, SPM, & stroke length
Gardner Denver PZ-11
1600 HP - 115 SPM - 11 inches
What is a FIT, what is the purpose of it & why is it performed at the shoe?
Formation Integrity Test, to apply surface pressure to equal an equivalent mud weight downhole, and test if the formation can hold it without exceeding fracture pressure.
The shoe should be the weakest point in the formation.
What is the equation for hydrostatic pressure & what 2 pressures do we want to stay in between downhole?
.052 * TVD * Mud Weight
Fracture pressure - Pore pressure
What does VBR stand for, what is the pressure rating & what sizes can it close on, why would we not prefer to close the lower VBR's?
Variable bore ram - 10,000 psi
3.5" - 5.5" - We lose access to the annulus
What is a TLO & what are the 4 questions for an AAR?
Targeted Learning Objective
What was supposed to happen, what actually happened, what were the differences, what can we learn
What does HMI & PLC stand for?
Human-Machine Interface
Programmable Logic Controller
Explain our flow path of mud while stripping, what is the purpose of stripping?
Mud Pump #1 - BLM Line - Kill Line (Into the BOP) - 4" Orbit valve - MPD Choke - Flow Line - Trip Tank - Mud Pump #1
To keep bottom hole pressure constant by applying surface back pressure
What is ECD (clearly state) & why is it important?
A measure of the total pressure exerted by the drilling fluid against the wellbore; combination of hydrostatic pressure (column of fluid) & dynamic pressure (friction from the fluid flowing)
Your ECD's may be high enough to exceed pore pressure, but your hydrostatic may not, leading to connection gas entering the wellbore
We want to circulate through the gas buster (the well is already shut in), what do we need to open/close & where do we read casing pressure at?
Open HCR, open super choke, open downstream, open return line
Crown valve
What are the 3 steps in an LMRA & what are the 3 kinds of error prone situations?
Stop, Think, Act
Work Environment, Task, Individual
What kind of valve is our super choke (power choke)?
Orifice valve
What is the purpose of running toe sleeves on production casing & why do we circulate casing after landing out?
To convey wireline guns downhole (fracing)
To ensure nothing was dropped inside of the casing while running
What is Murphy's law & what is XOM's expectation for well control?
Anything that can go wrong will go wrong
Know what the well is doing at all times
What kind of valves do we have on the accumulator & what are their settings?
3 position 4 way valves
Open - Close - Block
Name the 12 LSRA's
Confined Space, Bypassing Safety Controls, Energy Isolation, Excavation, Safe Mechanical Lifting, Hot Work, WAME, Working at Heights, Breaking Containment, Driving, Work Authorization, Line of Fire
