As low (risk) as reasonably practicable.
A group of hydrocarbon substances, including the alkanes and most of the other fractions found naturally incrude oil.
Naturally occurring paraffin fractions of which the molecules are based on a “straight chain” of hydrogen;saturated carbon atoms.
A refining process used to produce improved gasoline components with, for instance, lower pollutant effects.The process is also used in the manufacture of plastics.
A pattern of sedimentary deposit frequently laid down by streams or rivers where they spread out into plains.Alluvial fans from past geological eras are potential reservoir structures.
Alpha Thames’ incremental field development solution for the production and processing of subseahydrocarbons. It provides field control from reservoir to host, and can evolve to meet all future requirements.
The AlphaCPU™ (Central Processing Unit) is a diverless, seabed, modular, processing system for the productionof hydrocarbons, which forms the heart of an AlphaPRIME™ developed field. It comprises a foundation system,KeyMAN™ and a minimum of two System-Modules™. It utilises all-electric power and control for maximumefficiency and reliability. This ensures its suitability for all field developments including deepwater applicationsand those requiring long tie-backs.
Annulus master valve
A negatively charged ion; an ion that is attracted to the anode during electrolysis. Compare cation.
The ring-shaped cavity between two concentric tubes OR the space around a pipe in a wellbore, the outer wallof which may be the wall of either the borehole or the casing; sometimes termed the annulus.
