Good morning Jonsie! From my experience working with reputable third engineering firms to generate SEC approved reserve reports and as an expert witness for SEC reserve designations (damage amount for proven reserves only), I don't recall any "180 day rule". It may be an arbitrary time frame whereby if wells produce steadily for that amount of time, their reserves would definitely fall into the "Proven Reserve" category and it may even elevate "Probable" and "Possible" reserves into a higher (i.e. Probable to Proven?) category. Most likely, the 6 month time frame may simply be the total amount of time it takes to get a bunch new wells drilled/reworked and on line (basis for reserves revision), get a third party engineering report completed, submit it to the SEC and receive back the SEC blessing.
