Look---I'll help you out. Check out this glossary of common acronyms used in the oil biz.
Not sure where the author of this "glossary" gets his terms from as no source for the definition is provided. It is not an acronym widely used in the oil industry as you no doubt know since this is the only "glossary" that has it. The Schlumberger Oilfield Glossary which is the industry go to for all acronyms commonly used does not contain it and that glossary has been continually updated for the last twenty years. MSC is an acronym used all over the place, here is a link with 202 uses https://acronyms.thefreedictionary.com/MSC
Irrespective let me remind you that the prospectus does not define what the acronym MSC means in its expanded form other than to define it in their definitions section as:
The average maximum number of barrels per day of crude oil that can be produced for one year during any future planning period, after taking into account all planned capital expenditures and maintenance, repair and operating costs, and after being given three months to make operational adjustments.
that is the definition...what the letters stand for is immaterial given we know what they mean ...they defined it.
As to the rest of your blather let me also remind you that you claimed it was MPC....what the frig does that mean? Please find us where that acronym is used in the prospectus or better yet find where it is used in the oil and gas industry other than to describe Marathon Petroleum Corporation. Not sure why you appear to be so smug here when it is clear you have never read the prospectus.
