GEPLEADER Generator Sets Support Production Enhancement at Iraq's Ahdab Oil Field

The Ahdab Oil Field is located in the southwestern area of Kut City, Wasit Province, eastern Iraq. It is the first large-scale oil field project in Iraq developed by a Chinese enterprise. After years of production, some blocks have entered a high water-cut development stage, with certain production wells exceeding 60% water cut and significant reservoir heterogeneity, affecting crude oil recovery rates and economic efficiency.

The Ahdab Oil Field is not only a benchmark in Iraq's energy industry but is also renowned for its green development philosophy. The Central Processing Facility (CPF) at the field is the first integrated station in Iraq to achieve full coverage of oil, gas, and water treatment processes.

II. Project Challenges

The Ahdab Oil Field primarily features complex carbonate reservoirs. After 16 years of production and development, it has entered a medium-to-high water-cut stage, with declining reservoir pressure and rising water cut, making reservoir management increasingly difficult. To break through the resource potential bottleneck hindering sustainable development, Ahdab Company launched a "decisive water-cut reduction" campaign in 2025, aiming to reduce the comprehensive water cut from 70% to 50% within the next two years.

This production enhancement campaign has placed multiple challenges on the field's power support:

1. Surging power demand from production enhancement operations

To achieve the core objectives of stabilizing oil production, controlling water cut, and increasing reserves and production, the field requires a substantial number of new drilling, sidetracking, and production enhancement operations. The increased power load from new drilling equipment, Electric Submersible Pumps (ESPs), and water injection pressurization systems has placed significant pressure on the field's captive power plant capacity.

2. Extreme environment testing equipment reliability

Iraq has a typical desert climate, with summer temperatures often exceeding 50°C, and the oil field is located on the Mesopotamian Plain, where sandstorms are frequent. Generator sets must maintain long-term stable operation under harsh conditions of high temperature and heavy dust. Conventional equipment is prone to insufficient cooling, power derating, and frequent breakdowns in such environments. Additionally, the field is surrounded by environmentally sensitive areas, requiring equipment to meet strict environmental and noise control standards.

3. Extremely high requirements for power supply continuity

Once drilling operations are interrupted by power failure, it would not only result in direct economic losses of hundreds of thousands of dollars but could also trigger serious safety incidents such as wellbore collapse. Critical operations such as drilling and ESP oil recovery have a "zero tolerance" requirement for power stability and continuity – any power fluctuation could lead to production accidents.

4. Complex load management of the field's power grid

As the field undergoes rolling development, the power system load continues to increase, placing higher demands on grid stability. New temporary power equipment must achieve precise load matching and scheduling with the existing captive power plant to avoid system collapse due to overload.

III. Solutions

To address the unique power demands during the Ahdab Oil Field's production enhancement phase, GEPLEADER's technical team conducted on-site surveys and customized a comprehensive power support solution:

1. Flexible deployment of silent generator sets

GEPLEADER deployed multiple GEP-E series silent diesel generator sets at the Ahdab Oil Field, with total capacity flexibly adjusted based on the field's phased production enhancement needs. The units are equipped with advanced electronic fuel injection management systems, delivering continuous and stable power output – perfectly suited for high-load operations such as drilling, ESP oil recovery, and water injection pressurization.

2. Specialized optimization for extreme high-temperature environments

To address Iraq's extreme summer temperatures exceeding 50°C, GEPLEADER implemented targeted technical enhancements on the units. A unique inclined guided air intake structure significantly improves heat dissipation efficiency, while the oversized radiator design ensures stable, full-power, uninterrupted operation under sustained high-temperature conditions, eliminating the risk of overheating shutdown.

3. Intelligent parallel operation and load management system

Through an advanced intelligent parallel control system, multiple generator sets achieve automatic load sharing and redundant backup. The system seamlessly integrates with the field's existing Power Management System (PMS), automatically adjusting the number of operating units based on real-time load conditions – ensuring power reliability while optimizing fuel economy.
