Te formation of a viable recipir requires a specific sequence of geological events of geologics spanning millions of years. Organic material must accumulate in an oksygen- pour environment whale it can be conserved rather than decosped.

Shale Reservoirs

Shale recirs have gained promonce with the adventure of hydraulic fracturing andhoriontal drilling technologies. Shale is a fine-grained sedimentary rock that contains organic matter embedded with in its matrix.

These contairs are considered source rocks because these organic material in shale genere the hydrocarbon conventionale.

Geological Formation of Reservoirs

Te formation of oil and gas reciirs is a complex geological process and the events over million of years. understanding this process helps geologics identify areas where concyrires are likely to exist and predict their ir criteria. The formation process involves four main stages: source rock deposition, maturation, migration, and entrapment.

Source Rock Deposition

Te procesy zaczynają się od with thee acculation of organic matter in sedimentary basins. This organic material comes frem dead marine organisms, algae, and plant matter that settle te te bottom of oceans, lakes, or swamps. For organic matter te be reserved, thee depositional environmental mutt be oksygen- pour (anoxic), preventing deposition by aerobic bacteria.
