Revision Date: April 2024 
(NAG) FIELDS 
(b) the natural gas liquids (NGLs) constituting mainly of pentanes and 
pentane plus and plant condensates. 
(c) the field condensates drop-out from a production separator where 
such separators are installed. 
(iii) Dry marketable natural gas stream shall be measured using a meter with a gas 
chromatograph for compositional analysis. 
(iv) The NGLs shall be measured 
in 
a custody transfer unit configuration using 
meters 
which 
may 
include 
Coriolis 
meter 
and 
meet 
the 
Commission's 
measurement requirements. 
4.5.Other Measurement Methods 
The Commission 
may, where applicable and 
for the purposes 
of these 
incentives, approve the determination of NGLs by a back-up measurement 
method of fiscalisation in a tank. 
4.6.Metering Standards & Specifications 
(i) 
For the purposes of these incentives, the measurement and metering systems 
used shall comply with the acceptable industry standards such as: 
(a) Guidelines 
for the 
Determination 
of Quantity 
& 
Quality 
of Petroleum 
& 
Petroleum Products in Nigeria issued by the Commission.
