Customized AM600 Gas-to-Power for Two Associated Gas Sources
A contracted swamp oilfield development in Nigeria requires a practical route to use U1 separator gas and U4 LP separator gas for on-site power. CIMC ENRIC provides associated gas collection and a containerized AM600 gas power generation solution to reduce diesel dependence and turn treated field gas into useful electricity.
Diesel Cost and Flaring Cost Created a New Power Challenge
The oilfield asset has two operational wells, U1 and U4. The operator faces rising diesel cost for field power and increasing pressure to handle associated gas instead of treating it as waste. The project therefore needs an integrated gas collection and gas power generation package that can adapt to two different associated gas conditions.
Commercial pressure
- Diesel prices and remote logistics increase operating cost.
- Associated gas handling and flaring exposure can become a recurring cost.
- On-site gas-to-power can turn waste gas into direct field value.
Field condition
- Swamp oilfield environment in Nigeria.
- Two active associated gas sources: U1 separator gas and U4 LP separator gas.
- Wet associated gas requires practical conditioning before stable engine operation.
Solution intent
- Collect usable associated gas at the field.
- Condition and regulate gas for engine use.
- Generate reliable on-site power using a containerized AM600 system.
Sweet Associated Gas Suitable for Combustion Engines
The gas is reported as sweet, with no H2S detected and low CO2 content. It is suitable for direct-combustion gas engines after basic gas conditioning and pressure stabilization.
| Gas characteristic | Reported range / value | Engineering implication |
|---|---|---|
| Methane | 78% - 91% | Usable fuel gas range for engine review. |
| CO2 | 1.3% - 2.7% | Low CO2 content; derating impact expected to be limited subject to final gas review. |
| H2S | 0% | Sweet gas; lower corrosion and treatment burden. |
| Heating value | 965 - 1179 BTU/scf | Two gas streams have different calorific values; engine tuning and control strategy are customized. |
| Gas type | Wet associated gas | Basic gas conditioning, liquid management and filtration are required. |
| Specific gravity | 0.64 - 0.76 | Fuel control settings are reviewed for both lean and wet associated gas conditions. |
U1 and U4 Require a Customized Fuel Strategy
The project is not a generic genset supply. The AM600 package is configured around two well gas profiles so that the field can use available associated gas more effectively while reducing diesel dependence.
U1 Separator Gas
- Molecular weight: 18.58
- Specific gravity: 0.641
- Heating value: approx. 965 BTU/scf
- Gas type: lean associated gas
U4 LP Separator Gas
- Molecular weight: 22.12
- Specific gravity: 0.763
- Heating value: approx. 1,179 BTU/scf
- Gas type: wet associated gas
Associated Gas Collection Plus Containerized Power Generation
CIMC ENRIC combines gas-side handling with power-side generation so the field receives a practical, integrated path from associated gas to electricity.
Gas side
- Associated gas collection concept
- Basic gas conditioning
- Pressure regulation and fuel delivery
- Liquid and impurity management concept

From Disposal Burden to Field Power Asset
This signed project demonstrates how associated gas in Nigerian swamp oilfield developments can be converted into practical on-site power through a customized modular package.
Reduce diesel dependency
Use available field gas to reduce fuel purchase and logistics exposure.
Lower flaring pressure
Convert associated gas into electricity instead of treating it only as waste.
Adapt to gas variation
Configure the AM600 package around two associated gas qualities.
Replicable model
Create a smaller-scale route that can be expanded across similar oilfield nodes.
