Flyndre and Cawdor Environmental Statement
Non-Technical Summary
Bathymetry The measurement of ocean depth and the study of floor topography.
Benthic Relating to organisms that are attached to, or resting on, the bottom
sediments.
Bioaccumulate The increasing concentration of compounds within fauna such as limpets,
oysters and other shellfish.
Block Sub‐division of sea for the purpose of licensing to a company or group of
companies for exploration and production rights. A UK block is
approximately 200 – 250km 2 .
Demersal Living at or near the bottom of the sea.
Flowline Pipe through which produced fluids travel
Greenhouse gas Gas that contributes to the greenhouse effect. Includes gases such as
carbon dioxide and methane.
Greenhouse effect The greenhouse effect results in a rise in temperature due to infrared
radiation trapped by carbon dioxide and water vapour in the Earth’s
atmosphere.
Infauna Benthic organisms that live within the sediment.
Injection well Well into which gas or water is pumped to maintain reservoir pressure.
ISO 14001 International management system standard.
Macrofauna Larger bethic organisms.
Manifold A piping arrangement which allows one stream of liquid or gas to be
divided into two or more streams, or which allows several streams to be
collected into one.
Meiofauna Benthic organisms sized between 50µm and 1mm.
Microfauna Benthic organisms sized less than 50µm.
Pelagic Organisms inhabiting the water column of the sea.
Phytoplankton Free floating microscopic plants.
Tie‐in The action of connecting one pipeline to another or to another piece of
equipment.
Sidetrack Creation of a new section of the wellbore for the purpose of detouring
around an obstruction in the main wellbore or to access a new part of the
reservoir from an existing wellbore.
Special Area of
Conservation
Areas considered to be important for certain habitats and non‐bird species
of interest in a European context. One of the main mechanisms by which
the EC Habitats and Species Directive 1992 will be implemented.
Special Protection Area Sites designated by the UK Government to protect certain rare or
vulnerable species and regularly occurring migratory species of birds.
Thermocline Pronounced temperature incline.
Well completion The process by which a finished well is either sealed off or prepared for
production by fitting a wellhead.
Zooplankton Free floating microscopic animals.
