Well Control
What is "Stripping Pipe" in well control operations?
Stripping is the process of moving the drill string into or out of the wellbore under pressure while the BOP remains closed, or where an MPD system utilizes a Rotating Control Device (RCD) and an automated MPD choke manifold.
MDW
Measurement While Drilling
It refers to the evaluation technology that gathers real-time downhole data from the bottom hole assembly (BHA) while the well is actively being drilled, sending this information back to the surface.
Where is the Racking Board located, and who operates from it?
The racking platform is typically positioned 84 to 87 feet above the drill floor near the middle of the mast.
The derrickman operates from this platform.
What is the maximum PDS trough capacity in pounds?
Maximum trough capacity is 8,000 pounds.
How many Gardner‑Denver PZ‑11 pumps are included in the mud pumps system?
There are three Gardner‑Denver PZ‑11 1600 HP triplex pumps.
What is the primary difference between primary well control and secondary well control?
Primary well control relies entirely on the hydrostatic pressure of the drilling fluid.
Secondary well control utilizes mechanical surface equipment—such as the Blowout Preventer (BOP) stack, choke manifolds, and kill lines
MASP
"Maximum Anticipated Surface Pressure"
It is the highest pressure expected to be encountered at the surface during the drilling, completion, or workover phases of a well.
Why does H&P use round mud tanks on Mixing and Process skids?
Round tanks are specifically designed to allow for easier cleaning compared to standard square or rectangular tanks.
what should be used when laying down light weight tubulars such as drill pipe.
the Damper
What is the capacity of the mud system tanks? not including trip tanks.
The mud system has 708 barrels total active capacity.
What is a "Float Valve" (Drill Pipe Float) and how does it affect well control readings?
A float valve is a one-way check valve installed in the bottom hole assembly (BHA) just above the bit. It allows mud to be pumped down the drill string but prevents fluid from traveling backward up the pipe. If a kick occurs, a float valve will block the formation pressure from reaching the surface gauges, meaning the Shut-In Drill Pipe Pressure (SIDPP) will read zero until the pumps are slowly bumped to open the valve and read the true pressure.
SICP
"Shut in Casing Pressure"
It is the pressure measured at the surface on the casing side of the wellbore (the annulus between the drill pipe and the casing) when the blowout preventer (BOP) is closed and the well is shut in
What are Mast Raising Cylinders (MRC), and how are they powered?
These are custom hydraulic cylinders used to raise and lower the drilling mast. They are operated by a Hydraulic Power Unit (HPU) and are safely stowed on the side of the mast once the raising or lowering is finished.
What sits at the very top of a drilling structure to carry the drill line?
The Crown Frame/Block.
What is the maximum breakout torque of the PIPE HANDLING SYSTEM?
The maximum breakout torque is 80,000 ft‑lbs.
What is a "Diverter System" and when is it used instead of a BOP stack?
when drilling shallow surface holes before surface casing is set, it safely routes the escaping gas and fluid away from the rig floor to a downwind discharge line.
OEM
"Original Equipment Manufacturer"
What do the discharge and pulsation dampeners on a Mud Pump Skid do?
They are designed to minimize the shock and vibration created by the high-pressure mud pump during operations
What is the length range for drill pipe "triples" handled on FlexRig 3, 4S, and 5 rigs?
The lengths range from 90 to 94.5 feet.
What is the hookload capacity of the mast in the FlexRig design?
The mast has a hookload capacity of 750,000 pounds.
What is included in the blowout preventer equipment?
It includes 13‑5/8" double ram, single ram, and annular preventers, a 10M choke line, and a 10M choke manifold.
VFD
A Variable-Frequency Drive (VFD) house contains VFD units, which are adjustable-speed drives used to control the speed and torque of AC motors by varying the input frequency and voltage. The VFD units are housed on a skid known as the VFD house.
What is a Saver Sub and what is its specific purpose?
It is a short drill collar with male threads on one end and female threads on the other. It is designed to take the wear and tear of frequent makeup and breakout connections, protecting the more expensive threads on the top drive or kelly.
What is the maximum gull wings capacity in pounds?
Maximum Capacity of Gull Wings: 40,000 pounds of tubulars.
WHAT IS THE LENGTH OF THE SKID PACKEAGE FOR R 532?
100'
