UIC Monitoring Records

The monitoring a UIC permit requires, and the results recorded.

What this is

The monitoring records attached to a UIC permit: the date, the type of monitoring, the method used and the result.

How it is laid out

The Railroad Commission publishes this as Fixed-width ASCII. Columns are byte ranges with no separators, described only in a scanned record layout. We decode it into a table you can open anywhere. It has 7 columns and about 45.7K rows.

The columns you will most likely want:

  • cntl_no The UIC control number this monitoring row belongs to.
  • monitor_date Date of the monitoring event.
  • monitor_type What was monitored.
  • monitor_method How it was monitored.
  • monitor_result The result recorded.
  • row_no Sequence number of this row within its parent record. Part of the key.

…and 1 more, all documented on the full page.

What we add

Check that a disposal well's required monitoring is actually being done, and find wells whose monitoring results were adverse.

  • 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.

Worth knowing before you use it

Keyed on the UIC control number only — join to the inventory record to find out which well it is.

Monitoring type and method are short codes documented in the UIA010 manual's data-item notes rather than in a code table.

The full page lists every trap in this dataset.
