What this is:

PDA001, the gas half: PDF101, the same 102-byte EBCDIC tape structure for gas. 232,028 WELLS by RRC gas id, each with the last 26 reporting CYCLES, and on every cycle the P-2 production report, the gas and condensate dispositions by code, the commingle permit, the balancing-period status and the remarks -- ten tables in all. Two things here exist nowhere else on the site.

How it is laid out:

The Railroad Commission publishes this as EBCDIC (IBM cp037). IBM mainframe encoding (cp037). Opening it as text gives you nonsense; it has to be transcoded first. We decode it into a table you can open anywhere. It has 107 columns and about 232K rows.

The columns you will most likely want:

  • district RRC district as an INTERNAL district number, 01 to 14 -- not the designation the industry prints.
  • gas_rrc_id The well's RRC gas identifier as a whole number.
  • gas_code The tape's record marker, 'G' for a gas well, on all 232,028 rows.
  • gas_oldest_eom_balance Gas overproduction or underproduction, in MCF, carried into the oldest cycle the tape still holds.
  • cond_oldest_eom_balance Condensate in stock at the end of the oldest month on the tape, in barrels.
  • liquid_oldest_eom_balance Plant liquids at the end of the oldest month on the tape, in barrels.

…and 101 more, all documented on the full page.

What we add:

Put a gas well's allowable beside what it produced, follow 1,238,315 pipeline deliveries and 166,991 vented-or-flared dispositions across the state, read the operator's own explanation for the flaring, and find the 34,967 well-months inside a balancing period working off an imbalance.

  • Decoded out of the Commission's original format into something Excel opens.
  • Filterable before you download, so you can take one county instead of the whole state.
  • The Commission's single-letter codes translated into words.

Worth knowing before use:

THE GAS ALLOWABLE IS TRUNCATED. balancing_allow_amt is a three-byte packed S9(5) on the tape where the 2005 manual documents nine digits, so anything of 100,000 MCF or more wraps: RRC id 298707 in cycle 202506 reads 92,883 here and 492,883 in PDQ's lease_gas_allow.
