Shandong Green Power Co., Ltd. Sets New Milestone in Comprehensive Clean Energy Utilization

11 MW Associated Gas CHP Project Delivers Reliable Power and Heat at Jilin Oilfield

Integrated investment, engineering, equipment, O&M and digital control turn a variable oilfield gas stream into dependable distributed energy.

Shandong Green Power Co., Ltd. has passed final acceptance and brought an 11 MW gas‑fired combined heat and power (CHP) project into operation at the Honggang Oil Production Plant of PetroChina Jilin Oilfield in Da’an, Jilin Province, China.

Developed under a five‑year technical service agreement, the project covers two power stations and integrates project investment, engineering, construction, equipment supply, operation and maintenance. The system uses oilfield associated gas to generate electricity and recover useful heat, helping the site reduce fuel waste and lower its reliance on standalone gas‑fired boilers.

The Challenge: Making Variable Associated Gas A Dependable Energy Source

Associated gas is rarely as consistent as pipeline natural gas. Methane concentration, inert‑gas content, lower heating value, pressure and liquid carryover may fluctuate as field conditions change. At the same time, oilfield operations require stable power, predictable maintenance and safe operation.

The Jilin site adds a demanding winter environment, with temperatures falling to -25°C. A successful solution therefore had to address fuel‑gas conditioning, combustion stability, knock control, cold starts, thermal management, heat recovery and long‑term O&M as one integrated system—not as separate equipment packages.

One Service Framework From Project Development To Operation

Under the five‑year technical service model, Shandong Green Power assumes responsibility for the project’s defined investment, construction and O&M scope. For the oilfield operator, this reduces the burden of coordinating multiple suppliers and limits the upfront capital required for the energy system. For the project itself, it creates a single accountability chain from gas assessment and system design through daily operation and lifecycle maintenance.

The commercial structure is project‑specific. It is evaluated against available gas volume, gas quality, load profile, heat demand, local electricity value, operating hours and site risk.

Engineering Solution

Fuel‑Gas Adaptation And Combustion Control

An intelligent gas‑regulation and engine‑control strategy adjusts combustion parameters to changes in gas composition and heating value. Anti‑knock control and fuel‑specific calibration support stable operation while protecting the engine.

Cold‑Climate Reliability

Staged preheating, temperature interlocks, cold‑start logic and material selection are configured for low‑temperature operation. The design is intended to reduce cold‑start wear and maintain stable auxiliary‑system conditions during severe winter weather.

Combined Heat And Power Integration

Electricity is generated close to the point of use, while recoverable thermal energy is used to replace part of the heat otherwise supplied by conventional gas‑fired boilers. This cascading use of fuel is the basis of the project’s reported total energy utilization of at least 70%.

Digital O&M And Predictive Maintenance

Energy‑management and condition‑monitoring tools combine operating data, maintenance planning and predictive alerts. The objective is to identify deterioration early, schedule maintenance around production needs and reduce unplanned downtime.

Project Performance And Value

The two‑station system has a total installed capacity of 11 MW. Under the gas‑quality and operating conditions defined for the project, the reported electricity yield is at least 4.2 kWh per m³ of gas under project‑specified fuel and operating conditions, and total energy utilization is at least 70%.

The project also estimates annual emissions reduction of approximately 30,000 metric tons of CO2 by recovering associated gas, generating electricity onsite and replacing part of conventional boiler heat. Actual emissions performance depends on operating hours, displaced energy sources, gas composition and the calculation boundary used.

Why The Project Matters To Oilfield Operators

Gas‑to‑power projects are often treated as generator purchases. In practice, bankable performance depends on how the entire system is engineered: gas collection and conditioning, engine selection, electrical integration, heat recovery, load management, spare parts, remote monitoring and O&M.

The Jilin project demonstrates a repeatable delivery approach for oilfields and industrial sites with distributed fuel streams, including associated gas, coalbed methane, biogas and natural gas. Each project, however, must be designed from site‑specific gas analysis and load data.
