BOP when PIPE -> TOP and blind -> bottom?
Advantages:

PO - we can change all above blind rams
Disadvantages:
PI - cannot replace equipment below pipe rams
PO - cannot circulate
BOP when PIPE -> BOTTOM and blind -> top?
Advantages: PI - can change all equipment above pipe ram PO - pump and fluid up down (circulate) Disadvantages: PI - not able to circulate PO - not able to change and maintain
Define Hard shut in and advantages
1) HCR is closed
2) BOP is closed
Adv and disadvantages of HARD shut in
Adv: minimize influx (kick size)
Disadva: water hammer effect
Define Soft Shut In

2) BOP is closed
3) then slowly close choke valve
Adv and disadvantages of SOFT shut in
Adv: control to not exced macp
less pressure pulse
Disadv: let the bigger kick volume
HCR stands for
High Closing Ratio
