[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]
When you have a flow path to pump. Have you never been on a job with a sand up & tried to pump in the well & couldn’t but the well could flow all day long back at you? We know the casing seal assembly was tested & that was done right. There is now way they could have done that if the casing seal wasn’t seated.
