Record number: 1, Textual support number: 1 CONT
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
Record number: 1, Textual support number: 1 OBS
All cap rocks are impermeable, therefore making the terms "impermeable cap rock" and "impervious cap rock" redundant. 7, record 1, English, - cap%20rock
