Source rock
Is an organic rich mudstone or shale containing abundant plankton that formed in low energy, anoxic, marine conditions
1 of 17
Maturation
The process by which plankton is converted into petroleum by the effects of temperature and pressure during burial.
2 of 17
Migration
Describes the movement of petroleum from a source rock to a reservoir rock.
3 of 17
Reservoir rock
Is a highly porous and permeable rock preventing further upwards migration of petroleum.
4 of 17
Reserve
The amount of the resource that can be extracted at a profit using existing technology.
5 of 17
Blowout
Occurs when oil gushes uncontrolled to the surface
6 of 17
Primary Recovery
Is where oil initially gushes to the surface under natural pressure and is then pumped out.
7 of 17
Secondary Recovery
Is where water is injected below or natural gas injected above the oil to maintain the pressure.
8 of 17
Coal seam
A layer of coal, usually 1 to 2 metres thick.
9 of 17
Coalification
Is the diagenetic process by which peat is turned into coal by the effects of heat and pressure during burial.
10 of 17
Rank
Describes the percentage of carbon in the coal.
11 of 17
Coal series
The sequence of increasing rank from peat to anthracite.
12 of 17
Adit
Is a horizontal tunnel dug into a hillside
