Enhanced Oil Recovery - EOR. From Low Permeability Carbonate Rock Reservoirs. Phase 1 - Literature Review

摘要

The report outlines the well-known and tested enhanced oil recovery methods (EOR methods). The outline is based on a literature study and information obtained by visits at energy agencies and research institutions in Denmark and Norway. It has been the intention to describe all the well-known EOR methods. Each method has been evaluated for applicability under conditions, in particular to the low-permeable chalk reservoirs in the Danish North Sea. Technical as well as economic aspects are considered. In this report only the reservoir engineering aspects of the EOR methods have been discussed. Furthermore, the purpose has been to point out unsolved problems and questions to be answered for a more detailed evaluation of the application of the methods in Danish oil reservoirs. It is the intention that this report together with the results of further studies shall form the basis for an evaluation of the possibilities for application of enhanced oil recovery techniques in Denmark.
