The objective is to develop an in situ process for recovering shale oil using a fire front moving in a horizontal direction. The project is being conducted at a field site, Kamp Kerogen, located 70 miles south of Vernal, Utah. There are no retort nor production data included in this report because no retort was burned nor oil produced during the second quarter. Reclamation work has begun on Retorts number 24, number 25, and number 26. Final preparations were made in May to ignite Retort number 27. Five post-blast packer tests on Retort number 28 have been finished and results should be available in July. Construction of the off gas processing plant for Retorts number 27 and number 28 began in April. To date, the oil storage tanks, demister tanks, air coolers, ammonia absorber and stripper, the afterburner stack, the H/sub 2/S absorber, the steam generator, the ammonia stripper reboiler, and a small heat exchanger have been installed. The gas piping including the by-pass system through the plant is complete; the installation of process piping in the ammonia plant is nearly complete. Process modifications have delayed the piping in the sulfur plant. The ignition, vacuum and spare blowers are all operational. 10 figures, 4 tables.
