Update reports. [Progress of ongoing field tests of enhanced oil recovery methods]

This quarterly publication reports the progress of ongoing field tests of enhanced oil recovery (EOR) methods. Geological and engineering data published in the reports are supplied by operators. Basic information on the reservoir and fluid properties, along with maps, logs, and miscellaneous data are included in the initial report on each project; brief update reports are used to present new injection/production data and to report significant changes. The report also lists EOR projects which have been terminated.
