1. AMDP-11 Agar Multiphase Meter
Justification
To support wireline campaign flowing surveys - enabling gaslift optimisation
No AMDP-11 welltests for more than 1-1/2 years - PD Meter defecftive
AMDP-11 has ‘lots of gas production & little oil production’ - Why?
Pre-acid stimulation inflow performance measurement
Determination of correct Maximum Allowable Sand Production - MASP
Well review/optimization

2. AMDP-11 Agar Multiphase Meter
Results
Total of 27 welltests on 15 strings (average 1.2 per day)
Good quality welltest data including reliable measurement of gaslift gas
Gas use/production with no associated oil production - 165,000 m3/d gas
- 4 strings no liquid production - circulating GL gas - 75,000m3/d
- SWA-164 optimised - GL to natural flow - 30,000m3/d GL saved
- SWA-80 well closed-in on HWC - 60,000m3/d LP capacity enabled
Estimated oil gain from gaslift optimisation m3/d oil
Improved forecast quality and reduction of deferments
- CPL update - oil decrease 60m3/d, gas increase 120,000m3/d
- TPL on GL optimisation strings - potential 100m3/d oil
Acid stimulation confirmed SWA-252 & 164, cancelled SWA-222 & 175

3. AMDP-11/20 Agar Multiphase Meter
Conclusion
Use of Agar meter out-performed justification economics
Quality data enables up to 135,000 m3/d LP gas reduction
( 17% of single LP compressor capacity)
Quality data gives potential for 100m3/d oil production gain
( 27% AMDP-11 oil rate increase)
The Agar MPFM show good repeatability between tests.
All the repeat test show good relations between the gas injection, wellhead pressure ,gas out , and liquid flow rate.
Compare with the water cut sample show very good agreement. The fluctuation in sample values track well with the MPFM readings.
All test was perform with wells that produce more then 95% GVF, water cut between 65 to 80% , Liquid flow between 14 to 210m3/d and gas flow between 14 to 40 sKm3/d.
