Span of time since the formation of the oldest earth’s rocks, and that can be studied through the analysis of the geologic record. It is represented by a succession of rocky layers and divided into in [..]

Sedimentary rock with a high content of organic matter from which hydrocarbons are capable of being generated under the ideal burial conditions (temperature and pressure).

After generation, hydrocarbons are expelled from the source rock and pass through porous/permeable pathways and/or faults/fractures in the rocks towards the surface, and may encounter a trapped reserv [..]

Sedimentary rock that is sufficiently porous and permeable to store and permit the drainage of fluids contained in its pores. The main reservoir rocks are sandstones, made up predominantly of grains o [..]

Traps are combinations of reservoir and sealing rocks, arranged in structures or other geological features allowing the accumulation of oil and gas. Traps are capable of imprisoning petroleum after it [..]

Sealing rocks are impermeable rocks, such as shales, marlstones and evaporites, capable of blocking the passage of petroleum during migration. The effectiveness of a sealing rock also depends on its t [..]

Occurrence in the appropriate relative time of all the petroleum system elements and processes (source rocks, generation, migration, reservoir rocks/sealing rocks and trapping), allowing the accumulat [..]
