Two techniques have been field-tested. These are ''huff-and-puff'' CO/sub 2/ injection for stimulation of the producing wells and either alternate or simultaneous injection of CO/sub 2/ and water. Both process mechanisms are discussed and are illustrated, where possible, by the results of field tests in the United States. These have been in sandstone reservoirs containing light oils and heavy oils. Several other pilot or field projects are in the planning stage. A planned field demonstration project of both processes, in different test areas of a fractured limestone reservoir (oil 9/degree/-15/degree/) in Turkey, is summarized. The possible range of candidate reservoirs is discussed, and general economic comparison with steam injection is given. 27 refs.
