The Bureau of Economic Geology’s Geophysical Log Facility (GLF) was established subsequent to legislation passed by the 1983-84 Texas State Legislature in which all operators of oil, gas or geothermal wells were required to provide the Railroad Commission of Texas with at least one copy of a well log for each new, deepened, or plugged well. This requirement became effective in 1985, and the Bureau’s GLF has been the caretaker of the Texas Railroad Commission’s logs since that time.
An estimated 1.5 million logs are archived at the GLF, and include the RRC collection, donated logs from industry, and logs from Bureau research projects. Other datasets available at the GLF include Well Records, Driller’s Logs, Strip Logs, Mud Logs, Core Analysis, and Scout Tickets from thousands of Texas wells. Hard-to-find Texas well data is available in the GLF collection thanks to generous donations from industry, and provide a valuable source of information for the general public. Not all the data have been cataloged, but they are available to the public by visiting the Bureau of Economic Geology.
The Bureau provides scans of logs in TIFF format at a cost of $5.00 per log. Only the raster images of well logs are available, we do not currently offer LAS files. Once an order is processed, a link will be sent via email with instructions for downloading the image files, and an invoice will be sent for payment: we accept cash, checks, and credit cards.
To request logs or inquire about GLF resources, email: glf@beg.utexas.edu
The GLF is located on the first floor of Bureau headquarters in Austin and is open by appointment only.

The CONTINUUM Geologic Database is a searchable database for a large number of well logs and core holdings. Some Austin and Midland data are not currently included in CONTINUUM.
CONTINUUM is continually updated. If your search for data does not provide what you need, please contact Nathan Ivicic via e-mail or telephone (512-475-9561).
