So you cut and paste? I know what a ram bop is. We manufacture them. The ram bop cannot shear casing. Which was running through the BOPs when it exploded. The casing is minimum 16” diameter and con not be shearedn the wall of the pipe is too thin to close off. Understand the cementing process before you cut and paste and lecture based on your “readings.”. I work in the oil patch and have a bit more undrrstanding of the process than just “reading” about it.
con not shearedn undrrstanding
"Some can effectively close over an open wellbore, some are designed to seal around tubular components in the well (drillpipe, casing or tubing) and others are fitted with hardened steel shearing surfaces that can actually cut through drillpipe.
Don't you think you owe it to your competitor to tell them they are wrong?
In any event, despite, or perhaps because of your arrogance, (I don't know whose BOP failed, but I now have a suspicion), the BOP in this case failed to do it's job.
By the way, I've worn out more joints and rotary bits than you have socks. I got tired of midnight towers and learned how to engineer...
