In remote oilfield operations, stable electricity is essential for production, safety systems, water treatment, pumping units, communication equipment, and site accommodation. However, many oilfields are located far from reliable utility grids, while large volumes of associated petroleum gas (APG) are often flared or underutilized.

For this project, ALEO provided an APG gas generator and microgrid solution designed to convert available associated gas into dependable on-site power. Instead of treating flare gas as waste, the system turns it into a practical energy source for continuous oilfield operation.

Project Background

The customer operated a remote oilfield with limited grid access and high daily power demand. Diesel generators were previously considered for primary power, but long-distance fuel transportation, unstable fuel costs, and maintenance pressure created a high operating burden.

At the same time, the site had a steady supply of associated gas from oil production. Much of this gas was not being fully utilized, creating both economic waste and environmental pressure.

The project goal was clear:•Use associated gas as the main fuel source•Reduce diesel consumption and fuel logistics•Provide stable power for continuous oilfield operation•Build a scalable system that can adapt to changing gas flow and load demand•Improve energy efficiency while reducing routine flaring

Key Challenges

1. Variable Associated Gas Quality

Associated petroleum gas is not as stable as pipeline natural gas. Its composition may fluctuate depending on oil well conditions, production stage, and gas treatment quality.

Common challenges include:•Varying methane content•Moisture in the gas stream•Heavy hydrocarbons•Possible hydrogen sulfide or other corrosive components•Pressure fluctuation before entering the generator

These factors can affect combustion stability, engine performance, emissions, and long-term equipment reliability.

2. Remote-Site Reliability Requirements

Oilfield power systems must operate continuously in harsh outdoor environments. Unplanned shutdowns can interrupt production, damage equipment, and increase operational risk.

The customer required a system capable of:•Continuous prime power operation•Stable voltage and frequency output•Automatic load sharing•Fast response to load changes•Easy maintenance by local technicians•Remote monitoring support

3. Matching Power Demand with Gas Availability

Oilfield loads are rarely constant. Pumping systems, treatment equipment, lighting, HVAC, and auxiliary facilities create changing power demand throughout the day.

The power system needed to match load demand while also adapting to available gas volume. This required a coordinated microgrid control strategy rather than a single standalone generator.

ALEO Solution

ALEO designed a gas-to-power microgrid solution based on APG-compatible gas generator sets, gas conditioning equipment, paralleling control, and intelligent power distribution.

The system was configured to use associated gas as the primary fuel for on-site electricity generation, with optional diesel backup depending on site requirements.

System Configuration

The solution included:•APG gas generator sets•Gas pressure regulation and filtration•Moisture removal and gas conditioning•Automatic generator control panel•Synchronization and load-sharing system•Low-voltage or medium-voltage distribution equipment•Remote monitoring interface•Protection system for voltage, frequency, temperature, pressure, and gas abnormality•Containerized or skid-mounted structure for field deployment

How the System Works

Associated gas from the oil production process is first collected and conditioned before entering the generator system. The gas treatment process helps remove moisture, particles, and harmful components to improve combustion reliability.

After conditioning, the gas is supplied to ALEO APG gas generator sets. The generators convert the gas into electricity for oilfield loads. When multiple generator units operate together, the microgrid controller automatically manages synchronization, load sharing, start-stop logic, and system protection.

During periods of lower demand, the system can reduce the number of running units to improve efficiency. During higher demand, additional generator units can start automatically and share the load.

This modular operating strategy helps maintain stable power while avoiding unnecessary fuel consumption and mechanical wear.

Engineering Advantages

Better Use of On-Site Fuel

By using associated gas directly from the oilfield, the project reduces dependence on diesel delivery and makes better use of an existing energy resource.

Lower Operating Cost

Compared with diesel-based continuous power generation, APG power generation can significantly reduce fuel cost where associated gas is already available on site.

Reduced Flaring

Converting associated gas into electricity helps reduce routine flaring and supports a cleaner, more efficient oilfield energy strategy.

Modular Expansion

The system can be expanded by adding generator units as production capacity or site power demand increases.

Improved Power Reliability

Parallel operation and intelligent control improve redundancy. If one unit requires maintenance, other units can continue supplying power to critical loads.

Project Results

After implementation, the customer gained a more stable and economical on-site power source. The associated gas that was previously underused became a valuable fuel for daily operation.

The solution helped the oilfield achieve:•More reliable power supply for remote production•Lower diesel consumption•Reduced fuel transportation pressure•Better utilization of associated gas•Lower routine flaring•Flexible operation under changing load conditions•Improved energy independence for the site

Why ALEO

ALEO provides project-based generator and microgrid solutions for industrial, oilfield, mining, commercial, and remote energy applications.
