Hydrocarbon-generating potential of the Eocene Thebes Formation, Gulf of Suez: 1D basin modeling as a supplementary tool for source rock evaluation

摘要: The present work provides high-resolution modeling of the thermal maturation Eocene Thebes Formation using a multi-1D approach. model focuses not solely on maturity but also timing hydrocarbon generation (primary and secondary cracking), adsorption by organic matter, expulsion. time-lapse conceptual was developed well log data, geochemical analyses, composite logs. stratigraphic sequence Belayim Marine oil field subdivided into time series based tectonic framework Gulf Suez. An elevated basal heat flow has been assigned throughout rifting phases basin evolution. simulation for seven wells reveals variations in burial, history, accordingly maturity. predicted ranges from immature to mature with different tendency generate hydrocarbons (both primary and/or gas cracking) dependent kerogen type, development, burial history. Hydrocarbon (oil) starts after Messinian Time Event during deposition Post-Zeit Formation. related rather than evolution 113-M-27, BM-23, BM-65, BM-70 wells. Conversely, correlated principally development particularly 113-M-34 well. Expulsion occurred subsequent thermogenic (secondary cracking generated oil). It is possible investigate relationship between production index as consequence expulsion that reduced S1 values. levels (potential, active, effective source rock) allow differentiation regions potential accumulation were charged
