The Petroleum and Natural Gas Regulatory Board (PNGRB) regulates downstream activities like storage, distribution, and marketing—not upstream activities like production.

❌ I. Production of crude oil – Not regulated

• This is an upstream activity regulated by the Ministry of Petroleum & Natural Gas and Directorate General of Hydrocarbons (DGH), not PNGRB.

✅ II. Refining, storage and distribution – Partially regulated

• Storage and distribution are regulated by PNGRB.
• Refining is generally not directly regulated, though PNGRB may set standards affecting it.

✅ III. Marketing and sale of petroleum products – Regulated

• PNGRB authorizes entities to market notified petroleum products and natural gas.

❌ IV. Production of natural gas – Not regulated

• Like crude oil, it’s an upstream activity, not under PNGRB.
