The stated objective of this study is to build a solid engineering foundation to serve as the basis for field mini- and pilot tests in both high and low oil saturation carbonate reservoirs for the purpose of extending the technology base in carbon dioxide miscible flooding. The six tasks in this study are as follows: summary of available CO/sub 2/ field test data: summary of existing reservoir and geological data; selection of target reservoirs; selection of specific reservoirs for CO/sub 2/ injection tests; selection of specific sites for test wells in carbonate reservoirs; and drilling and coring activities. The report for Task Two summarizes existing reservoir and geological data on carbonate reservoirs located in west Texas, southeast New Mexico, and the Rocky Mountain states. It is contained in two volumes, each with several parts. The present volume, in four parts, is a summary of reservoir data for fields in the Permian basin of west Texas and southeast New Mexico.
