Environmental Impact of the Oil Industry
- drilling operations,
- disposal of drilling wastes,
- installation of well casing, and
- generation of industrial wastes.
Oil Production
- provision of access to sites by land and/or water,
- maintenance of a well head,
- flow lines,
- construction and maintenance of flow stations,
- separation of oil, water and gas at the flow station,
- disposal of waste water,
- disposal of gas, by re-injection, flaring or further processing,
- transport of processed crude oil by pipeline to the oil terminal, and
- generation of industrial wastes.
Gas Processing
- pipelines,
- gathering stations and
- Liquefaction plants.
LIQUEFACTION PLANT AT BONNY
The Nigerian LNG project consists of the construction and operation of a new 5.8 mtpa capacity liquefied natural gas plant on Bonny Island in south-eastern Nigeria. The project will include the following elements:
- A two-train gas liquefaction plant (LNG plant);
- A 219 km gas transmission system (GTS) linking the plant by pipeline to the gas supply fields;
- Associated utilities, storage/loading facilities and other infrastructure;
- Six ocean going cryogenic vessels;
- Residential quarters for the Company's permanent employees on the Bonny Island.
The plant site and residential area were cleared of vegetation in 1979 and hydraulically placed sand was added in 1981 to raise the level of the sites. The process involved the relocation of Finima village which was started in 1980 ... Nigeria LNG Ltd therefore inherited a cleared plant site and residential area, and the environmental and socio-economic impact off this clearance is therefore not considered in the Environmental Statement for the LNG plant.
