(iii) 
Gas Conditioning or Treatment plant 
It 
refers 
to 
a 
facility 
where 
raw 
natural 
gas 
undergoes 
various 
treatments, including dehydration, sweetening (removal of hydrogen 
sulfide), and compression, to meet pipeline specifications or other end- 
user requirements and further processing. 
(iv) 
Gas Processing plant 
This 
is 
a facility where fractionation 
of the of the NGLs take place. 
Following conditioning, the processing plant splits the natural gas liquids 
into 
their 
constituent components 
like 
ethane, 
propane, 
butane, 
pentanes, pentane+(condensates). The processing plant may also refer 
to 
all 
processes 
covering 
the 
functions 
of 
NGL 
extraction 
and 
fractionation. 
(v) 
Hydrocarbon Liquids Content (HLC) 
This refers to the hydrocarbon liquids from the split or drop-outs of raw 
wet non-associated natural gas (NAG). The lighter end contains the dry 
marketable or sales natural gas, and the heavier ends are separated 
and captured as natural gas liquids (NGLs) and condensates. This might 
include ethane; propane & butane (LPGs), pentanes, and pentane plus 
(C5 and C5+) and shall be measured in barrels (bbl.) 
It includes both 
field condensates as well as plant condensates and natural gas liquids. 
(vi) 
— Inventory of all NAG fields or reservoirs 
This means the list of all discovered NAG fields and or reservoirs in the 
asset 
area 
including 
their 
dates 
of 
discovery, 
commitment 
and 
production status, in-place volumes, cumulative production, and any 
current activities (if any) on the asset. 
(vil) 
| Natural Gas Liquids (NGL) 
This refers to the liquid hydrocarbons that are extracted or produced 
along with raw natural gas. NGLs typically include ethane, propane, 
butane, isobutane, pentane, pentane-plus. These liquids are separated 
from raw natural gas during processing where the gas phase containing 
mainly methane is removed from the raw gas stream leaving the natural 
gas liquids.

© NGL Extraction Plant 
This 
is the plant where the raw natural gas after pretreatment and 
conditioning is separated into the sales dry gas and natural gas liquids.
