In addition to removing the \ character from CSVs, they must also be processed to remove the quotation character " to allow for proper importation. Older yearly CSV files (non-monthly) were split using a CSV split utility in order to meet MySQL's 2048KiB filesize limit | In addition to removing the \ character from CSVs, they must also be processed to remove the quotation character " to allow for proper importation.

Updating Production data. Extra column for WELL_API had to be added, using Well Permit #. Excel formula ="37-"&B2 was used to produce WELL_API values. Well Permit # renamed to WELL_API_COUNTY_ID. Extra columns WELL_COUNTRY set to "United States" and WELL_STATE_CODE set to "PA".
Needed to specify that lines were delimited by \n instead of auto to get around PHP "invalid comma count error." There was a typo in one cell for a sheet that had a "\" character, which produced another invalid column count error. Also renamed all columns in CSV to columns in SQL db as follows:
WELL_API, WELL_API_COUNTY_ID, PERIOD_ID, PRODUCTION_INDICATOR, WELL_STATUS, FARM_NAME,WELL_ID, SPUD_DATE, GAS_QUANTITY_MCF, GAS_PRODUCTION_DAYS, CONDENSATE_QUANTITY_BBL, CONDENSATE_PRODUCTION_DAYS, OIL_QUANTITY_BBL, OIL_PRODUCTION_DAYS, AVERAGED, OPERATOR_NAME, OPERATOR_ID, WELL_COUNTY, WELL_MUNICIPALITY, LATITUDE_DECIMAL, LONGITUDE_DECIMAL, UNCONVENTIONAL, CONFIGURATION, HOME_USE, REPORTING_PERIOD, COMMENT_REASON, COMMENT_TEXT, WELL_COUNTRY, WELL_STATE_CODE
which needs to be entered on the import screen for PHPmyAdmin to upload correctly for column headers.
This has been more work than it should have been. There is a CSV module in python if we elect to go for full automation, so this could possibly be done automatically.
