Investigating deep geological reservoirs using seismic reflection and well logs, Tawila oil field, Yemen: Implications for structural setting and reservoir properties

CO2 Sequestration and Enhanced Oil Recovery via the Water Alternating Gas Scheme in a Mixed Transgressive Sandstone-Carbonate Reservoir: Case Study of a Large Middle East Oilfield

“…Geologically, Yemen is categorized under three rift-generating tectonic systems, out of which two of them occurred during the Mesozoic Era and one during the Cenozoic Era, , and they are typically linked by major faults. This extensional tectonics regime associated with the Mesozoic and Cenozoic eras of rifting emerged in petroleum structural traps in all the refit basins in Yemen, and these comprise fault-bound horst blocks and tilted blocks. , The Sayun–Masilah rift basin originated in the premature Kimmeridgian and persisted into the premature Cretaceous. ,, The generalized stratigraphic sequence in the sedimentary of Yemen including the Sayun–Masilah Basin has been investigated and identified by several studies. , They reported that the sedimentary region has a thick Mesozoic rock tracked by Cenozoic rocks. Significant regional unconformities caused by tectonic and/or erosion occurrences have been identified and highlighted, as shown in Figure .…”
