Schlumberger: Output may dip by 26-27 percent

New Delhi: New York-listed contractor Schlumberger – the sole bidder in state-owned ONGC’s tender for raising oil production from aging fields – has sought several deviations from the bidding norms, including projection of a 26-27 per cent decline in output in next few years. ONGC had invited bids for raising the output at its two oilfields – Geleki and Kalol in April 2018.
