A Review of Reservoir Rock Typing Methods in Carbonate Reservoirs: Relation between Geological, Seismic, and Reservoir Rock Types
Carbonate reservoirs rock typing plays a pivotal role in the construction of reservoir static models and volumetric calculations. The procedure for rock type determination starts with the determination of depositional and diagenetic rock types through petrographic studies of the thin sections prepared from core plugs and cuttings. In the second step of rock typing study, electrofacies are deter...
متن کاملModelling of wettability alteration processes in carbonate oil reservoirs
Previous studies have shown that seawater may alter the wettability in the direction of more water-wet conditions in carbonate reservoirs. The reason for this is that ions from the salt (sulphat, magnesium, calsium, etc) can create a wettability alteration toward more water-wet conditions as salt is absorbed on the rock. In order to initiate a more systematic study of this phenomenon a 1-D math...
متن کاملOrigin of petroleum in the Neoproterozoic–Cambrian South Oman Salt Basin
The South Oman Salt Basin (SOSB) is host to the world’s oldest known commercial deposits. Most of the South Oman oils have been proven to be associated with the source rocks of the Neoproterozoic to Cambrian Huqf Supergroup, but the assignment of oils to specific Huqf intervals or facies has been hampered by the geochemical similarity of the organic matter across the entire Huqf sequence, possi...
متن کاملThe Late Cenomanian-Coniacian Gattar and Aleg reservoirs in Sidi Bouzid area, Central Tunisia: Logging, diagenesis and reservoir implications
At the Sidi Bouzid area located in Central Tunisia, Cenomanian-Turonian reservoir rocks are well outcropping, especially in the Jebel el Kébar and Meloussi areas. The present work confirms that these carbonate intervals constitute the lateral equivalent of the Early-Middle Turonian Biréno and Late Turonian-Coniacian Douleb reservoir Members which are included within the pelagic marls of the Tur...
متن کاملRadiotracer Assay of Microbial Processes in Petroleum Reservoirs
Oilfield microbial communities exist under conditions of hampered exchange of water and mass and at a constant temperature; they are independent of the modern atmosphere and sunlight and may be considered closed or semi-closed systems. Crude oil is the main source of organic matter in this ecosystem. Microbial growth in reservoirs can be limited by the low content of phosphate and ammonium nutr...
