Fuel is one of the most critical resources in Once Human, powering your base infrastructure and enabling progression. Whether you’re running generators, refining facilities, or advanced machinery, a steady fuel supply becomes essential as you expand your settlement. This comprehensive guide covers everything you need to know about establishing a productive fuel farm, from the initial setup requirements to advanced optimization techniques.
Understanding Fuel Farming Fundamentals
Fuel farming in Once Human operates as a semi-passive system once properly configured. The process relies on extracting crude oil from underground deposits and refining it into usable fuel through specialized facilities. The entire operation requires careful planning of your base layout, power management, and production chain coordination.
The fuel farming system revolves around two primary production stages. First, crude oil is extracted from natural deposits using water pumps. Second, this crude oil is processed through refining facilities to create portable mixed fuel or premium fuel variants. Each stage demands specific resources, power allocation, and structural placement.
Essential Prerequisites for Fuel Operations
Before establishing your fuel farm, several foundational requirements must be met. These prerequisites ensure your operation runs smoothly and reaches maximum efficiency.
Memetics and Technology Unlocks
The first step involves unlocking critical memetics through your technology tree. You must obtain the Water Pump Memetic, found under the Logistics category in tier 03, positioned after water filter technologies. Additionally, unlock the Fuel Refinery Memetic from the Infrastructure section in tier 02. These unlocks provide the building blueprints necessary for your fuel operation.
Power generation represents another crucial prerequisite. Before placing extraction equipment, you must establish a reliable power infrastructure. Understanding your base’s energy requirements and capacity limitations prevents operational failures. Advanced generator technologies, specifically Advanced Biomass or Hydraulic Generators, become essential as your operation scales.
Locating Oil Deposits
Oil veins are distributed across the game world, with particular concentrations in specific regions. The Red Sands area contains abundant crude oil deposits, especially surrounding the Blackfell Oil Fields located at coordinates 5257,-1545. These dark, river-like formations visible on your map indicate underground oil reserves. Crude oil sometimes appears in surface puddles, making visual identification easier during base location scouting.
Strategic base placement near these deposits eliminates transportation inefficiencies. Position your settlement directly over or adjacent to oil veins to maximize extraction potential from day one. Avoid contaminated areas, as water pumps in polluted zones extract polluted water instead of crude oil, rendering them useless for fuel production.
Building Your Fuel Farm Infrastructure
Water Pump Placement and Configuration
Water pumps serve as your primary crude oil extraction mechanism. Access the Build menu, navigate to Facilities, then Production Processing, and finally Gathering & Production to locate the water pump blueprint. Unlike traditional resource gatherers, water pumps extract oil from any location within your base territory, eliminating location-specific placement requirements.
Each powered water pump produces approximately 12 crude oil per hour. Recommended farm configurations include placing 5-6 water pumps as your foundation. This quantity provides sufficient crude oil input for downstream refining operations while maintaining reasonable power consumption.
All water pumps must connect to your power grid. Without electrical connection, they remain inactive regardless of proximity to oil deposits. Verify each pump receives power before considering your extraction phase complete.
Refining Facility Setup
Refining facilities convert crude oil into usable fuel products. These structures require two inputs: electrical power and crude oil. Each refining facility consumes 10 watts of power during operation.
The refining process follows a specific conversion schedule. A single refining facility transforms 10 crude oil into 5 portable mixed fuel over a 60-minute production cycle. This rate means your facility processes fuel continuously provided crude oil remains available.
Install at least 6 refining facilities to match the crude oil output from 5-6 water pumps. This balanced configuration prevents bottlenecking, where either resource accumulates unused due to downstream capacity limitations. As your operation expands, maintain this proportional relationship between extraction and refining capacity.
Power Management and Energy Optimization
Generator Requirements
Power production represents the most expensive operational cost in fuel farming. Advanced generators address this challenge more effectively than basic alternatives. Both Advanced Biomass and Hydraulic Generators produce 30 watts of electrical output each.
A single fuel farming set—comprising one water pump and one refining facility—consumes 20 watts of power while operating. With maximum generator capacity of 180 watts (using six Advanced generators), you can theoretically support nine complete fuel farming sets simultaneously.
Electric Eel Deviations
Electric Eel deviations provide an efficiency boost that amplifies generator output. Assigning six active Electric Eels to each generator provides approximately 10 additional watts per generator. This enhancement effectively grants you three additional fuel farming set slots, pushing theoretical maximum production capacity significantly higher.
Production Output and Scaling Strategies
Calculating Your Production Capacity
Understanding production mathematics helps you plan expansion appropriately. The following table illustrates input-output relationships for standard fuel farming equipment:
| Facility Type | Power Consumption | Input Material | Output Product | Hourly Production |
|---|---|---|---|---|
| Water Pump | 10W | None | Crude Oil (1 per 5 min) | 12 crude oil |
| Refining Facility (Tier 1) | 10W | 10 crude oil | 5 portable mixed fuel | 5 portable mixed fuel |
| Refining Facility (Tier 2) | 10W | 50 portable mixed fuel | 1 barreled premium fuel | 1 barreled premium fuel |
Portable Mixed Fuel Production
Without Electric Eel enhancements, nine fuel farming sets produce 45 portable mixed fuel per hour at maximum capacity. This baseline accounts for proper power distribution and material flow throughout your operation. With Electric Eel assistance, this figure increases to 60 portable mixed fuel per hour, providing approximately 1,440 fuel daily.
Premium Fuel Conversion
Premium fuel production requires a secondary conversion step. An additional refining facility dedicates processing capacity to this higher-tier output. The conversion ratio demands 50 portable mixed fuel to produce 1 barreled premium fuel. Dedicating 10 of your fuel farming sets toward premium fuel production yields one premium fuel per hour.
If you maintain a stockpile of portable mixed fuel, you can accelerate premium fuel creation. Each refining facility converts stored fuel continuously, potentially yielding 15 barreled premium fuel per hour until your portable mixed fuel reserves deplete.
Layout and Base Design Considerations
Physical placement of your fuel farm affects operational efficiency and base aesthetics. Organize water pumps and refining facilities in logical clusters, grouping related equipment together. This organization simplifies power distribution and material transfer between processing stages.
Power lines represent a secondary consideration. Minimize cable runs by positioning generators near high-demand facilities. However, don’t sacrifice production efficiency for visual appeal—proper functionality takes priority during the planning phase.
Account for future expansion when establishing your initial layout. Leave accessible space for additional pumps and refineries as your base grows. Cramped facilities become difficult to modify or expand later without complete reconstruction.
Common Mistakes and Troubleshooting
Insufficient Power Distribution
The most frequent error involves underestimating power requirements. Players often build pumps and refineries without confirming adequate generator capacity. Verify your total power output exceeds your farm’s consumption before expecting production.
Contaminated Water Extraction
Placing pumps in polluted areas produces contaminated water rather than usable crude oil. Always verify your base location sits in a clean zone with access to uncontaminated oil deposits. Relocating after discovering this issue wastes significant resources.
Material Bottlenecking
Imbalanced extraction and refining capacity causes resource accumulation issues. Maintain equal or slightly higher refining capacity relative to crude oil extraction to prevent backups.
Frequently Asked Questions
Can I farm fuel without unlocking all memetics?
No, both Water Pump and Fuel Refinery memetics are mandatory. These unlock the specific building blueprints required for fuel production. Without these technologies, you cannot construct the necessary facilities.
What happens if I run out of power?
All unpowered facilities cease operation immediately. Fuel production halts, and crude oil inventory remains static. Restore power supply to resume operations.
How frequently must I check on my fuel farm?
Once properly configured with adequate power and materials, your fuel farm operates autonomously. Periodic checks ensure no equipment malfunctions, and you can retrieve accumulated fuel as needed. Most players check daily but could visit less frequently without production loss.
Should I prioritize portable mixed fuel or premium fuel?
Most players benefit from focusing on portable mixed fuel initially. Premium fuel production requires additional investment and only becomes valuable once your base expansion demands higher-tier fuel types. Establish stable portable mixed fuel production first.
Advanced Optimization Techniques
Once your baseline fuel farm operates smoothly, several optimization paths become available. Implementing Electric Eel deviations significantly boosts generator output without requiring additional infrastructure investment. These deviations multiply your production capacity effectively.
Monitoring resource stockpiles helps identify production imbalances. If crude oil accumulates rapidly, increase refining capacity. If your refineries remain idle, expand extraction operations. Dynamic adjustments maintain optimal efficiency as your base evolves.
Consider establishing multiple smaller fuel farms rather than one massive facility. Distributed operations provide redundancy—if one farm suffers equipment damage, your other operations continue functioning. This approach also distributes power requirements across your base more evenly.
