Methanol Generator Sets: Superior Performance for Plateau Drilling Operations

Comparison of Methanol Generator Set and Diesel Generator Set Operating in Plateau Areas

In plateau regions, methanol generator sets start more easily and have stronger adaptability than diesel generator sets, whereas diesel generator sets generally suffer from starting difficulties and usually require various auxiliary measures to operate normally. The following is a detailed analysis of the performance differences between the two in plateau environments:

PART 01

No Power Attenuation in High-Altitude Hypoxic Environments(Critical for Drilling Operations)

• Diesel Engine: Suffers severe power attenuation above 3,000 meters above sea level, making it difficult to drive rigs, mud pumps and other equipment.

• Methanol Engine: Has low dependence on oxygen, maintaining full power output in high-altitude, low-temperature and even closed wellsite environments.

Actual Effect: Rigs operate without shutdown or stalling, significantly improving drilling efficiency.

PART 02

Environmentally Compliant, Avoiding Inspection and Restriction Risks

Drilling operations are mostly conducted in the field, mining areas or ecologically sensitive zones with strict environmental protection requirements.

• Methanol Generator Set: Smokeless, low noise, low emissions, high environmental impact assessment (EIA) pass rate. No work stoppages, fines or equipment detention due to excessive exhaust emissions.

PART 03

Significantly Lower Fuel Cost Than Diesel

The calorific value of methanol is about half that of diesel, but its price is only about 1/3 of diesel.

The actual cost per kilowatt-hour is 30% to 45% lower than that of diesel.

Drilling operations usually run 24/7, resulting in a considerable difference in fuel costs per month.

PART 04

Stable Continuous Operation, Suitable for Long-Time Drilling

Drilling requires uninterrupted power supply and cannot afford shutdowns.

• Methanol Generator Set: Gentle combustion process, less engine wear, low failure rate, longer maintenance intervals, less engine oil consumption, effectively reducing time losses caused by shutdown maintenance.

PART 05

High Safety, Non-Flammable and Non-Explosive, Safer Wellsite

• Diesel: Low flash point, volatile, easy to cause fire in case of open fire.

• Methanol: High flash point, not easy to spontaneous combustion or explosion, more in line with wellsite safety specifications. Lower risks in storage, transportation and refueling.

PART 06

Excellent Low-Temperature Starting Performance, Adaptable to Northern/Field Winter Operations

• Diesel: Prone to wax deposition and difficult starting in winter, often requiring auxiliary means such as oil pan heating.

•

• Methanol: Smooth low-temperature starting, able to start normally at -20°C to -30°C, especially suitable for winter drilling operations in Inner Mongolia, Xinjiang, Northwest China and other regions.

PART 07

No Black Smoke Emission, Avoiding Equipment and Site Pollution

Black smoke from diesel generator sets adheres to rigs, instruments, steel wire ropes and other equipment, making it difficult to clean.

Methanol generator sets produce almost no carbon deposits and black smoke, keeping equipment clean and reducing maintenance workload.

PART 08

Stable Supply Chain, Immune to Sharp Oil Price Fluctuations

Diesel often faces problems such as supply restrictions, price hikes and queuing for refueling.

Methanol has sufficient domestic production capacity, stable supply and small price fluctuations. Long-term project costs are controllable, facilitating budget formulation and settlement.
