The Oklahoma Well Log Library (OWLL) is a non-profit organization (501 C-3) for geologists, geo-scientists, engineers, and landmen engaged in oil and gas exploration, production operations, and related activities. The library has an extensive historical collection of production records, scout cards, well logs, and base maps. Our data covers all 77 counties in Oklahoma and additional information can be found for Texas district 10, Kansas, North Arkansas, and Southeastern Colorado. Lots of our files contain both current and historical well data and many unique hard to find data sets that cannot be found anywhere else. The Oklahoma well log library is the first stop for many and is an essential resource to those in the oil and gas profession.
OWLL is a membership owned library but is also available for use and benefit of the general public as well as it members. We are also a supporter of students and faculty of educational institutions, and waive access fees to those who provided proper identification and proof of enrollment. In addition, we have many reciprocal agreements with other geological libraries in Texas and Oklahoma.
