Improving efficiency of oil recovery and finding a source of watering in multi-zone deposits by geochemical methods of research

open access: yesGeoresursy, 2020
One of the strategic ways in the development of multilayer fields is to identify the source of water inflow into the well production and, as a result, to eliminate it with subsequent optimization of the production of non-watered formations.

Geotechnological regulation of the development of oil fields with hard-to-recover reserves

open access: yesKazakhstan journal for oil & gas industry, 2023
Background: A significant proportion of the remaining oil reserves of the fields under development is confined to reservoir zones with low-permeability and undersaturated reservoir, thin reservoirs. Maintenance of oil production levels in such deposits is possible through methodological study and development of recommendations for optimizing and ...
