[QUOTE=alcor;38401]The intention would be to maintain BHP in order to ensure no further influx occurs. We’d need to maintain an overbalance. We would bleed off pressure to allow the bubble to expand, thereby reducing the pressure as it migrates. We don’t want to break down the weak formation so our overbalance is limited. We have to ensure that the influx volume size is known. We bleed off whatever volume is required to maintain BHP with a slight overbalance.
Our Rams are closed. We can even Shear the pipe. All is well.
Well intervention is not my speciality, but as you’ve pointed out we can run wireline to perforate the Production Casing and then circulate the gas out.
Where there’s a will there’s a way.
There are hundreds of recorded wells where bleeding and pumping has been a way of securing the well back to Primary well control.[/QUOTE]
I am glad to know you understand well control basics. That does not change anything. This well started coming in when gas started migrating & changing places with the mud. As they would have allowed the bubble to expand more gas influx would have taken its place & you would have the same conditions that caused the occurance. I wish they would have caught it sooner & I wish they would have at least bought themselves more time, then we may not have been having these fun times over the last several weeks. But whether you admit it or not, This well was going to blow out once the gas started migrating up the hole. From the blowout Kasol showed the video of I believe this one would have been several times wors & possibly could have capsized the whole rig & killed everyone. Whether it happened at 21:50 or 0200 the next morning it was coming & I think deep down you realize that now. You can driticize the crew all you want for not running the game plan, but a hail mary at that point when you’re already down by 3 touchdowns just doesn’t get it.
