Serving the Permian Basin for over 61 Years!
The Library's log collection is searchable online nine different ways.
New logs are added daily. If we don't have the log you are looking for, we usually can find it.
Our collection also includes unreleased and donated logs and runs from the 1920's to the present.
Texas Logs - Collection covers the entire state of Texas. The logs were released between 1985 and 1998.
220,000 Microfiche Logs (All over Texas, not just the Permian Basin).
Wyoming Logs - Collection covers the entire state of Wyoming. The logs, some 26,000, were released between 1950 and 2007.
Library has a microfiche viewer-printer-scanner where one can view, print or make a digital image (PDF or TIF) of a log.
The entire PBSL log collection along with index cards was acquired by the Library in 2008. The PBSL was the primary company providing Stratigraphic Logs for the Permian Basin.
There are some 16,000 logs in Texas, 6,000 in New Mexico and a few in Arizona, Utah and Arkansas. Both Wildcat wells and trending Field wells are included.
Coverage begins on May 15, 1944 when the sample lab was formed until December 31, 1969, covering a period of 25 years and 7-1/2 months.
The PBSL's log description collection was acquired by the Library and contains over 30,000 logs stored in 20 filing cabinets.
These descriptions are detailed, handwritten and were transcribed by geologists for the PBSL.
Coverage begins around 1944 and runs through 1993.
Permian Basin Mud Log Collections
Subsurface collection of approximately 4,215 mud logs in West Texas (filed by operator) and Southeast New Mexico (filed by township and range).
Bettis Brothers Mud Log donation of 4,560 logs covering the Permian Basin filed by operator in Texas and by township and range in New Mexico.
Hand Written Tickets (H)
500,000 Permian Basin scout tickets covering a period of time beginning in the late 1950's and running into early 2011.
In the late 1950's, Williams & Lee (and subsequently IHS) inaugurated a commercial scouting service using printed tickets to replace the hand written tickets that had existed since the Scout Check was formed in the 1930's--when all scouting information was exchanged verbally at the Scout Hall in Midland every Wednesday morning.
Coverage begins in the 1930’s and runs to the 2000’s.
