Algeria Oil Fields Map

Algeria — Oil & Gas Overview

Algeria is a long-standing OPEC member with mature oil basins (notably Hassi Messaoud) and one of the world’s largest gas systems centered on Hassi R’Mel. Most proven reserves and production are onshore; offshore remains limited. Crude output has hovered around ~0.9–1.0 million b/d in recent years under OPEC+ management, while marketed natural-gas production and exports keep Algeria among Europe’s key suppliers.

Production snapshot (latest public sources)

Crude oil: ~0.91 million b/d (Nov 2024, secondary sources, OPEC MOMR).
Role in Africa: Largest natural-gas producer and #2 in total liquids in Africa (EIA 2025 brief).
Proved reserves (indicative): ~12.2 billion bbl crude; ~159 Tcf (4.5 Tcm) natural gas reported in major references.

Major fields & plays

Oil: Hassi Messaoud (flagship, Sahara Blend), Ourhoud, Rhourde El Baguel; broader Berkine Basin clusters.
Gas: Hassi R’Mel (giant), and newer Sahara tight-gas hubs (e.g., Timimoun/Reggane/Ahnet developments).

Exports & routes

Pipelines to Europe:
- TransMed (via Tunisia to Italy): capacity reported up to ~33 Bcm/yr.
- Medgaz (direct to Spain): expanded ~10–10.7 Bcm/yr; record flows to Spain in 2024.
LNG export terminals: Arzew (GL1Z, GL2Z, GL3Z) and Skikda (GL1K) complexes with multiple trains; individual trains range roughly ~1.3–4.7 mtpa each.

Operators & partnerships

State company Sonatrach leads upstream and export infrastructure, partnering with international firms on PSCs and redevelopments (e.g., Berkine and Illizi area deals announced 2025).

Notes & sources

Field names and “giant field” classification align with Dr. M. K. (Mike) Horn, AAPG Datapages compilation used across CCCarto. Recent production and infrastructure details cross-checked against OPEC (MOMR/ASB), the U.S. EIA country brief, Sonatrach/LNG references, and reputable industry reports. Most Algerian reserves/production are onshore; offshore remains limited.

Field Acronyms

EUR_MMBOE = Estimated ultimate recovery in million barrels of oil equivalent

Giant oil and gas fields = those with 500 million barrels (79,000,000 m3) of ultimately recoverable oil or gas equivalent.
