Listed below are links to cross-sectional illustrations of Enhanced Oil Recovery (EOR) Methods, drawn by Joe. R. Lindley, Publications Specialist at the former National Institute for Petroleum and Energy Research (NIPER) in Bartlesville, Oklahoma. The drawings were published in NIPER's 1986 Enhanced Oil Recovery Information booklet as part of the U.S. Department of Energy (DOE) EOR research program. Mr. Lindley's technical descriptions of the recovery processes were updated in 2001 and summary descriptions of the various groups of illustrations were added.

The set contains 18 drawings, in both black-and-white and color versions. The illustrations are in pdf format for printing and downloading. To view, click on the links below. Viewing with one of today's sophisticated pdf readers provides a choice of options, including text copying of the process descriptions and view enlargement for the illustrations, a useful tool for reading some of the smaller print.

These drawings, illustrating major principles of oil recovery, are in the public domain and may be used, cited and published as appropriate. Proper acknowledgment should include the U.S. Department of Energy and this office as the source.
