Well Lifting Capability to a Green Power Generation Using Microturbine Generator
Abstract A new way of utilizing access gas to power generation using newly developed technology named micro-turbine electric generator (mTEG). This technology is using relatively low gas flow rate: same region of gas-lift consumption between 0.3 – 0.5 MMscf/d of power generation for a minimum of one kilo Watt (1kW) per unit. The technology is classified under green category is due to no combustion process instead using pressure differential as the mechanism for power generation. Therefore, it supports PETRONAS’ net carbon zero program especially for unmanned platform operation. The mTEG is simple unit developed based on differential method by allowing gas to flow inside for rotation without combustion for power generation. Flow and pressure requirements are relatively low at 0.4 MMscf/d at 10 bar, respectively. One of gas supply sources to run the unit is coming from well or gas lift skid. Per skid of mTEG it can produce up-to 4 kW power. This technology helps to support unmanned platform operation to reduce operation cost and moreover, this technology is compact and superior than solar power scheme unit. Life cycle cost between the two technologies was indicated superior saving is possible for mTEG technology. Completed prototype model – integrated skid and in 2019 team managed secured full in-house development under prototyping and engineering centre unit located in PETRONAS Research Sdn. Bhd. (PRSB), Bangi. One of the technologies used to produce the mTEG unit is 3D printer with also available in PRSB. Passed factory acceptance test (FAT) in 2019 based on positive outcome of endurance test performance. Embarked detail engineering for installation of the skid and completed electrical and installation in 2020 and the skid unit is expecting to provide 1 kW power by end of this year at field E and upon completing the test, this technology will be able to benefits other operating unmanned platform or event small plant operation. The technology was designed for green power generation: operation greenification with no combustion elements instead provide flexibility for recycling of the gas and reuse for another means such as gas lift gas application to improved oil recovery.
