Setting flow alarms (Deviation Mud Volume)
- Identify the Deviation Mud Volume gauge and its low and high set controls.
- Pump mud at 80 SPM and set the flow alarms as follows:
- Place Trip Tank Select Switch to high position
- Use the Coarse switch to select number of barrels at which alarm should go off.
- Use High Adjust switch to set alarm by turning it till the red light comes
on, then back off slowly till the red light goes off. - Place Tank switch to the Low position
- Use Low Adjust switch and repeat as in (iii).
- Replace Tank switch to Tank position
- Use Course switch to zero the gauge.
Setting Flow Alarms (Return Mud Volume)
-
- Use the Level Adjust switch to zero the gauge.
- Set the High Alarm by turning the High Adjust switch until the
red light comes on, then back off slowly until the light just goes
off. - Identify the Return Mud Volume gauge and its Low and High Adjust
controls. - Set the low alarm by using the Low Adjust switch and
repeating as in (ii).
Identifying Kick Warning Signs
- Watch for increased flow rate on the Return Mud Flow gauge and visual
alarm. - Watch for influx volume increase on the Deviation Mud Volume gauge
and visual alarms indicators. - Watch for string weight change and drilling break on the
Geolograph charts.
Utilizing Shut-in Procedures to Kill Well.
A. When a kick is suspected, conduct a flow check as follows:
- Shut down pumps.
- Pull out of hole (POOH)
- Stop Rotary Table
- Watch flow alarms. If on, probably a kick.
SOFT SHUT-IN
B. At BOP, open the Choke line.
C. Close the Annular Preventer
D. Observe the SIDPP and SICP and wait till both pressures stabilize.
HARD SHUT-IN
A. Close the Annular Preventer
B. Observe the SIDPP and SICP and wait till both pressures stabilize.
Well Control Computations (Kill Sheet Preparation)
Below is a pre-recorded data for a specific well configuration. Examine
and study the various parameters carefully.
