Crude Extraction

Zero Domestic Production

Crude oil is pumped from underground reservoirs in oil-producing countries. The Middle East (Saudi Arabia, UAE, Iraq) accounts for ~31% of global production.

Philippine Context

Philippines produces virtually zero crude oil domestically. The country imports 95% of its petroleum needs, primarily Dubai crude from the Middle East.

Maritime Transport

Two Chokepoints, One Lifeline

What happens here

Crude oil travels via supertankers (VLCCs carrying 2M barrels each) through critical chokepoints. A single disruption can spike global prices within hours.

Philippine Context

Philippine-bound crude passes through the Strait of Hormuz (35% of seaborne oil) and the Strait of Malacca before entering the South China Sea.

Refinery Processing

One Refinery for 115 Million People

Step 1

Crude Intake

Raw crude is desalted and pre-heated before entering the distillation tower. Impurities and water are removed.

Step 2

Distillation

Crude is heated to 400°C+ in atmospheric and vacuum columns. Lighter products rise, heavier ones sink.

Step 3

Cracking

Heavy residue is broken into lighter, more valuable products through catalytic and hydrocracking processes.

Step 4

Blending & QC

Finished products (gasoline, diesel, jet fuel) are blended to specification and tested before storage.

What happens here

Refineries heat crude oil to 400°C+ in distillation columns, separating it into gasoline, diesel, jet fuel, LPG, and other products. Each crude type yields different product ratios.

Philippine Context

Petron Bataan Refinery is the ONLY operating refinery in the Philippines (180,000 bpd capacity). All other fuel is imported as finished product from Singapore and South Korea.

What happens here

Import terminals receive both crude oil (for Bataan) and finished petroleum products. Tank farms store fuel before distribution to regional depots.

Philippine Context

Major import terminals in Batangas, Subic, Limay, and Rosario handle the bulk of Philippine fuel imports. Terminal capacity determines how many days of supply the country holds.

Local Depots

Island Logistics, Mainland Costs

What happens here

Regional depots receive fuel from terminals via pipeline, barge, or tanker truck. They serve as last-mile distribution hubs for gas stations in their area.

Philippine Context

The Philippines has ~50 depots nationwide. Island geography means many areas rely on inter-island barges, adding cost and vulnerability to weather disruptions.

Crude Oil Benchmarks

Global oil prices are set by three key benchmarks. Understanding which one matters for the Philippines explains why our pump prices sometimes move differently from what you see in US-centric news.

Brent Crude

North Sea Benchmark

Used globally as the primary price reference. Light, sweet crude (low sulfur content). Produced from North Sea oil fields. Brent sets the tone for roughly two-thirds of globally traded crude.

WTI

West Texas Intermediate

The US benchmark crude. Slightly lighter than Brent. Trades at a discount to Brent due to the US shale production surplus. Delivered at Cushing, Oklahoma.

Dubai/Oman Crude

Asia-Pacific BenchmarkPH Reference

The Middle East benchmark that matters most for Asia-Pacific. Medium, sour (higher sulfur). THIS is what Philippines prices are based on. When Dubai crude moves, Philippine pump prices follow within 2–3 weeks.

Crude Oil Properties

Light vs Heavy

Light crude yields more gasoline and diesel per barrel (more valuable). Heavy crude yields more fuel oil and asphalt (less valuable but cheaper to buy). API gravity above 31.1° is classified as light.

Sweet vs Sour

Sweet crude has low sulfur (<0.5%), making it easier and cheaper to refine. Sour crude has high sulfur, needing more processing. Dubai crude is sour, which is why Petron Bataan needs a special hydrodesulfurization unit.
