[QUOTE=Cynthia;37395]I watched the whole CGMMS hearing again this weekend. Out of curiosity, Hafle at one point states that (I’m paraphrasing) [I]no other company in the GOM runs cbls on this kind of job[/I]. I find that to be a dramatic statement. Is that true? From my reading of documents about cementing in this kind of well, it is recommended to use them, especially when shorting on centralizers and running nitrogen foamed cement on the final production casing string, and with losses in the zone. Yet, he states that no other companies do it in the GOM either. If this is so, is it a best practice, or, a fallacy of common practice?
He says one other thing that catches my attention, and I’ll paraphrase; He doesn’t agree that cementing needs or is supposed to isolate the production zone, or to prevent the flow hydrocarbons into the system, before moving off, apparently because he has one other barrier to rely on, (and because a completions crew can come back in and fix it.) Isn’t that an egregious error to make with redundant barriers? Isn’t the idea to have multiple [I]fully functioning[/I] barriers? [/QUOTE]
Who is Hafle again?
