Completion Casing Records — what it is, in short

What this is

The repeating casing rows of a completion packet: size, weight, depth set, hole size, cement type and amount, slurry volume, top of cement and how it was determined.

This is the completion-time view of casing. The wellbore database's casing records are the Commission's maintained view of the same hole; they do not always agree, and where they disagree the difference is itself informative.

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 17 columns and about 1.1M rows.

The columns you will most likely want:

tracking_no The completion packet's RRC tracking number.
packet_id Identifier of the completion packet this row belongs to.
parent_id Identifier of the G-1 or W-2 record this row hangs off.
row_no Sequence number of this row within its parent record. Part of the key.
casing_size Casing outside diameter, inches, as filed.
weight_lb_per_ft Casing weight, pounds per foot.

…and 11 more, all documented on the full page.

What we add

Audit a well's cementing programme as filed, and compare what the operator reported at completion against what the wellbore database carries today.

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

Every measurement is stored as text as filed. Weights appear in two columns because operators sometimes report a range.

Rows are ordered within a packet by row number; there is no depth ordering guarantee.
