A look at ONGC-I

Sep 24, 2007

Over the next few articles, we will look at ONGC’s fundamentals using the accounting equation framework to capture the following questions:

  1. Where does the company source its money? (Equity and liabilities)
  2. How is the money then deployed? (Assets)

  3. What does the deployment lead to? (Expenses and Income, resulting in a profit or loss).

We begin with assets first because they are the most important element in understanding ONGC, which primarily engages in the exploration of oil and natural gas (upstream activity). However it also has refining, petrochemicals, power and SEZ assets.

Upstream assets

  1. Domestic oil and natural gas fields held:
    • Independently

    • Through joint ventures

    • Through production sharing contracts (contract for allocation of reserves discovered) with the government in blocks under New Exploration Licensing Policy (NELP-a government initiative to attract private investment in exploration).

  2. International oil and natural gas fields held through:
    • Subsidiary- ONGC Videsh Limited. (OVL)
    • Subsidiaries of OVL
    • Joint ventures of OVL
Downstream assets
  1. Refineries held through:
    • Subsidiaries-MRPL
  2. Petrochemical complexes through:
    • Joint ventures-OPal & OMPL
Other non-hydrocarbon assets
  1. Upcoming power plant in Tripura
  2. SEZ projects at Dahej, Mangalore and Kakinada.

Important financial assets

  1. Equity investments in Indian Oil Corporation and GAIL.

  2. Government of India oil bonds.
  3. Fixed deposits with banks.

Domestic upstream assets
Oil and gas deposits are found in fields (accumulation of oil and gas) within basins (geological depressions on the Earth’s surface filled with sedimentary material).

Where? The principal domestic basins in which ONGC has independent operations are -Mumbai Offshore, Cambay, Krishna Godavari (KG), Cauvery and Assam & Assam-Arakan. The company is also present in CBM-BPM Basin near Kolkata and Frontier Basin near Dehradun. It may be noted that ONGC is also present in these basins through several joint ventures.
