The technology selected for the NGL extraction would depend upon 
the operating objective of the facility and the inlet gas composition and 
might 
include 
technologies 
such 
as 
JT 
Valve 
(Valve 
Expansion), 
Mechanical Refrigeration or Tulboexpander. 
Non- Associated Gas Field 
This 
is a field where the reservoirs hold predominantly natural gas with 
no oil. In some cases, the reservoirs may also hold such natural gas with 
associated condensates or natural gas liquids in the case of retrograde 
condensate fields. 
Plant Condensates 
Any gas condensate produced from a gas conditioning plant or gas 
processing plant downstream of the production separator. 
Production Separator 
This 
is a piece of equipment downstream the wellhead, designed to 
separate the mixture of fluids produced from the well into its various free 
components. For 
a NAG well this will be used to separate the raw natural 
gas fluids produced from the well into condensates, gas, and water. 
Raw Natural gas 
This is natural gas as 
it is extracted from underground reservoirs before 
Undergoing any processing or treatment. Raw natural gas typically 
contains methane, along with varying amounts of other hydrocarbons, 
impurities such as sulfur compounds (e€.g., hydrogen sulfide), and water 
vapor. Raw natural gas could be lean and dry (with little 
if any heavy 
ends) or rich and wet (with heavy ends) depending on the reservoir 
type. 
Separation facility 
This 
shall 
mean 
a 
gas 
production 
separator, 
gas 
treatment, 
conditioning, or processing facility where the wet gas is separated into 
hydrocarbon liquids and dry natural gas. 
Wet Gas 
This is raw natural gas containing significant amounts of the heavier ends 
i.e. natural gas liquids (NGLs) 
or condensates on surface conditions 
produced from the non-associated gas well. Wet gas differs from dry 
gas, which 
primarily consists 
of methane with 
minimal amounts
