Hydrocarbons (oil and gas) are an important energy source and feedstock for the petrochemical and other industries. Egdon is involved in the exploration and production of conventional oil and gas in the UK and the exploration for unconventional oil and gas resources in the UK.
Egdon’s primary near-term focus is on conventional oil and gas reservoirs which is where the oil and gas are found in porous rocks. The oil and gas have migrated from the organic rich shale rocks which are the source for the oil and gas to porous reservoir rocks where the fluids have been trapped by natural seals to form a reservoir. The trap can be either a structural trap (where the rocks are folded or faulted to generate a trap for oil/gas) or a stratigraphic trap (where the reservoir rock changes properties laterally to form the trap).
Unconventional oil and gas reservoirs occur where the oil and gas became trapped within the organic rich shale rock itself. This type of hydrocarbon is typically found at greater depths than conventional oil and gas. The shale rock is much less permeable and typically requires hydraulic fracturing to enable the oil or gas to begin or continue to flow.
On 4 November 2019 the government announced that it will introduce a temporary moratorium on hydraulic fracturing for shale gas.
