Free. You will be asked to confirm an email address before the files are built — that is the only gate, and it is there so we can tell you when a large export is ready.
What this is
Record type 07. The production tubing in a wellbore: size as whole inches plus a fraction, the depth it is set to and where the packer sits.
What you can do with it
Establish the completion configuration of a well, and check that a packer is set above a perforated interval as an injection permit requires.
Gotchas
Tubing size uses the same whole-plus-fraction encoding as casing: 2 7/8 inch is 2, 7 and 8 across three columns.
Record layout
9 columns. Byte positions are 1-based and come from the RRC record layout, so you can check our decoding against the original file yourself.

| 1 |
api_county
key

smallint | 3-5 | WB-SEGMENT-COUNTER |
Sequence of this tubing string within the bore. | — |
| 4 |
tubing_inches

integer | 6-7 | WB-TUBING-INCHES |
Tubing diameter, whole inches. | — |
| 5 |

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.
Wellbore Tubing Records joins to Full Wellbore Database (ASCII) on API county and API unique — many rows here share a single row there.
its tubing strings
One row per tubing string, with the packer depth. Keyed on the API county and unique number, which is how every record type in WBA091 hangs off its root record.
full-wellbore-ascii.api_county = wellbore-tubing.api_county AND full-wellbore-ascii.api_unique = wellbore-tubing.api_unique
