A numerical simulation study of CO 2 injection for enhancing hydrocarbon recovery and sequestration in liquid-rich shales
CO2 EOR Tight formations Experimental design Response surface modeling Recovery of shale liquid CO2 sequestration
2018/4/2
Less than 10% of oil is usually recovered from liquid-rich shales and this leaves much room for improvement, while water injection into shale formation is virtually impossible because of the extremely...
Experiences with forest reclamation of settling basins after industrial processing of manganese ore and pyritic shales
forest reclamation settling basin manganese ores
2015/3/5
This article describes the problem of forest reclamation of settling basins after industrial processing of manganese ore and pyritic shale at the age of 20–30 years. Soil properties of anthropogenic s...
Mineralogic Characterization and Petroleum Potential of Clays (Shales) of the N’Kappa Formation (Paléocene-Eocene) in the Douala Sedimentary Sub-basin (South-West Cameroon)
Mineralogy Organic Matter Petroleum Potential
2013/3/11
The aim of this research work was to report a facies analysis of the N’Kappa formation, identified the clay minerals present in those facies and evaluate their oil potential. For that to be done, Lith...
