Abstract

Flare gas is light hydrocarbon gas, by product of any petroleum industry activities, that is flared; and it could not pass into production facilities due its to low pressure. The gas flare volume frequently is significant, causing greenhouse gas emissions which gives serious environmental issue. Aims: The purpose of this research is to utilize flare gas in oil and gas fields to reduce environmental issue. Methodology and Results: Flare gas in an oil producing field is compressed to produce higher pressure gas flow, by using three one-stage Integrated Reciprocating Compressors to enter the production trunk line. The gas is flown to CO2 Removal Plant, as the gas would be gas sales. The subject field in West Java, the production wells experiences pressure decline; resulting the wellhead flowing pressure becomes low, so the gas is being flared. The gas flare recovery system is economically profitable both for purchase and rental scenarios. Renting the equipment is more profitable and has lower technical risk, because all risks is burdened to rental service provider. Conclusion, significance and impact study: Monetizing flare gas will reduce environmental issue, and it is utilized for own use or gas sales. The best Economics Scenario is rental scenario.

Abstract

Flare gas recovery is needed to handling gas flares in oil and gas fields. Field C production wells experience a decline as a result the gas flow pressure in the wellhead becomes low. Low pressure gas enters the LP separator then is burned as a gas flare containing CO2 of 33.38 mol and GHV of 1048.9 BTU / ft3. The flare gas recovery system is applied to reduce gas flares with the integrated reciprocating compressor unit for compression at suction pressure ± 10 psig, discharge pressure ± 100 psig and total flowrate ± 1 MMSCFD. Then the CO2 removal plant produces gas with a CO2 content of 7.09% mol and GHV of 1314.9 BTU / ft3. During operation, requires gas fuel ranging 11 MSCFD and the actual power ranges from 36.46 HP and 39.64 BHP. Economic aspects analysis, gas flare monetization for the period of 2015 until 2022, gross reserves 2,062,917 MMBTU and gross income of US$ 6,026,744. The operating cost of the the lease purchase scheme, the government US $ 2,079,696 and the contractor US $ 1,386,464 with POT 1.7 years and IRR 151.5%.
