What this is

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

What you can do with it

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

Gotchas

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.

Record layout

7 columns. Byte positions are 1-based and come from the RRC record layout, so you can check our decoding against the original file yourself.

uic_monitoring 7 columns

# Column Type Bytes RRC name Meaning Lookup
1 cntl_no key join text The UIC control number this monitoring row belongs to.
2 monitor_date date 3-10 UIC-MONITOR-DATE Date of the monitoring event.
3 monitor_type text 11 UIC-MONITOR-TYPE What was monitored.
4 monitor_method text 12-41 UIC-MONITOR-METHOD How it was monitored.
5 monitor_result text 42-71 UIC-MONITOR-RESULT The result recorded.
6 row_no key integer Sequence number of this row within its parent record. Part of the key.
7 ingested_at timestamptz When the upstream pipeline last wrote this row. Not an RRC field — it is EZRRC's provenance stamp, and it is what the freshness badge is measured against.

What this joins to

The Railroad Commission never states these keys anywhere in the files. They are the reason the data is hard to use, so here they are with the exact columns on both sides.

UIC Monitoring Records joins to UIC Database (ASCII) on Cntl number — many rows here share a single row there.
