Objective 1. Effective hole-cleaning with consistentconnection practice
2. Minimise off-bottom work to maintain a gaugehole for good hole cleaning and trippingconditions
# Operational Description Comments
1.
Drill stand down Driller to inform on radio when connection passes
table for depth calibration do not stop
Verify depth
2.
Pull off bottom + 2m using max 1 min Keep drilling RPM Keep 100% flow Read torque and weight as required
Full drilling parameters for maximum hole-cleaning.
3. Stop rotation
4.
P/U and record stable up and down weight Pull up 3-5 m and go down, max 10 m/min 100% flow moving up If ECD is high, stop 10sec on top before moving down 100% flow moving down if conditions allows (else
80% flow moving down) Stop pumps
100% flow to maintain hole-cleaning.
5.
Set slips on downward movement and make connection Fill pipe immediately w/400-1000lpm* while M/U
connection Do not start rotation
* Dependent on hole condition and hole size.
Minimize static time to avoid settling of cuttings.
6.
Survey and Start up sequence When returns increase to 100% flow (max 1 min) Open slips Open compensator if required Wait 30-45 seconds after reached minimum turn on
flow for MWD (300 gpm) Increase to drilling RPM
If delayed survey is used, go directly to drilling withoutwaiting on (IN-SYNC)
Obtain survey and apply hole cleaning parameters as fastas possible.
7.Drill ahead
Check pressure response when going on bottomAvoid going on bottom too fast.
Excellent consistency
