Abstract:
The classification of oil deposits by the complexity of their development and classification of enhancing reservoirs recovery (by R.Kh. Muslimov) are given. The considerable role of matrix solid material, and most importantly, of an active mineral phase, forming the paltry part of the entire rock, in oil displacement Is shown. Some measures, the Implementation of which would contribute to the effective development of fields with hard-to-recover oil reserves are recommended.
