MOST OIL COMPANIES will eventually face this problem but for ONGC it has become acute: most of its oilfields are in a state of natural production decline.

To combat the decline ONGC has begun Improved Recovery Schemes in up to two dozen of its worst hit properties. The most high profile of these are the Mumbai High North and Mumbai High South redevelopment schemes, which together will cost Rs8, 185cr ($1.71bn).
