Oil and gas become trapped in the subsurface where there is a barrier formed by impermeable rocks, such as well-cemented lithologies, mudrock and evaporite beds. These impermeable lithologies are known as cap rocks. The hydrocarbons will find their way around the cap-rock barrier unless there is some form of hydrocarbon trap that prevents further upward migration.  6, record 1, English, - cap%20rock

All cap rocks are impermeable, therefore making the terms "impermeable cap rock" and "impervious cap rock" redundant.  7, record 1, English, - cap%20rock

Natural gas is most commonly stored under pressure in three different types of underground facilities. The most common type of storage facility is depleted oil and natural gas fields. Converting a field from production to storage has the advantage of existing infrastructure such as wells, gathering systems, and pipeline connections. The second most common type of natural gas storage facility is natural aquifers, which are frequently used in the Midwest. Natural aquifers are suitable for gas storage if water-bearing sedimentary rock is overlain with an impermeable cap rock but usually require more base gas than depleted oil fields. Caverns constructed in natural salt deposits are the third most common type of storage facility and are used primarily along the Gulf Coast.  2, record 2, English, - storage%20facility

There are only four basic kinds of stratigraphic traps: unconformities, porosity permeability pinchouts, reefs, and drape structures. ... Reef Traps. Reefs are productive in many parts of the world. Many types exist, such as atolls, table reefs, pinnacle reefs, barrier reefs, fringing reefs, biostromes, and bioherms. They occur as small dome like features that may be reflected in the overlying sediments by drape. ... The size of a reef ranges from a few acres to several square miles. Seismic exploration is the best way to find reefs. The reef core grows upward and usually outward as the sea level rises. Detrital reef material falls on the ocean side, forming the fore reef. The back reef is formed on the lagoon or quiet side by deposition of limestone and lime mud ...  1, record 4, English, - reef%20trap

Stratigraphic traps are traps created by the limits of the reservoir rock itself, without any structural control.... Stratigraphic reef traps are amongst the most important type of trap in Alberta, where reefs of Devonian age, formed mainly of stromatoporoids host much of the petroleum. They became ideal traps when a change in the regional environment caused the reefs to be buried by muds, forming an impermeable seal and cap rock.  2, record 4, English, - reef%20trap
