[QUOTE="Biggsly, post: 1291440, member: 11136"] I went on a well several years ago when I was in well-control. It was in Spearman Tx. They had pumped acid using a straddle packer. It is a tool about 25 feet long that has an inflatable packer on both ends. You pack off both ends so that you can pump into one zone and no others. After they pumped the acid down hole, the packer would not deflate. They could not pull it out of the well. We killed the well 3 times and would time how long it would stay dead before it would kick off again. Once we had a time "about 30 minutes" we broke all of the bolts expect 4 on the bottom of the BOPs. When they killed it the last time, we had to jump in the cellar, brake the last 4 bolts and had a crane pick up the well head and BOP, and then tied another crane to the packer and pulled it out. Then we had to get the well head and BOP bolted back down before it kicked off. It was pretty scary. If it would have kicked off with no well head and BOP, we would have been screwed. All went well.
