Based on my investigation, I can verify this claim:

Reasoning:

• Nigeria holds approximately 209-211 trillion cubic feet (Tcf) of proven natural gas reserves according to official data from the Nigerian Upstream Petroleum Regulatory Commission (NUPRC) and OPEC's 2025 Annual Statistical Bulletin¹²³⁴
• Nigeria has the largest gas reserves in Africa, ahead of Algeria and Egypt⁴
• Nigeria ranks as the 8th largest gas reserve holder in the world⁵
• The reserves consist of both associated gas (102.59 Tcf) and non-associated gas (106.67 Tcf)³²
• Despite these vast reserves, Nigeria currently only produces about 4.3-8 billion standard cubic feet per day, indicating significant untapped potential²⁴
• The government has launched the "Decade of Gas Initiative" to leverage these reserves, aiming to increase reserves to 220 Tcf by 2030⁴²

Overall validity: 100%
