WRT to 1 and 3. The sleeves are open with a shifting tool conveyed by coiled tubing. The tubing and shifting tool stay in the hole during the fracturing operation. The OD of shifting tool is close to the casing ID dimensions so when deformation occurs, the shifting tool can become stuck. WRT...

JBA, Here is a link to the SPE website and a paper on cemented sleeves. https://www.onepetro.org/journal-paper/SPE-0513-0154-JPT?sort=&start=0&q=cemented+sleeve+fracturing&from_year=&peer_reviewed=&published_between=&fromSearchResults=true&to_year=&rows=25#

thank you for your response. You're absolutely right in the scenario that you mentioned the vertical well with good cementing and perforating, the pressures would be balanced. In this case we're talking about a horizontal well where cementing is problematic and it's very likely that there is a...

This is large scale oilfield pipe, similar to what you might use for surface pipelines. The normal burst pressure is about 8000 psi. It is not perfectly round but it is pretty round. General we are running a few thousand feet of it and would not caliper it. I am really trying to understand...

Thank you

The situation is that we have 4.5 inch diameter pipe with a 300,000 lbf yield rating installed in a horizontal completion. The pipe is cemented in place but it is very likely that the one side of the pipe may not have any cement in it. During the fracturing operation, a sleeve is opened and...

Hi, I am new to the physics forums. I am an older engineer with an interest in keeping my mind sharp and getting help with questions that I should already have answers to. ;)
