E&P contracting brief: Part II – 4 Dec 2025

1) Seven-day GeM bid extension keeps Mehsana rig earthing contract open as ONGC balances safety-critical scope with bidder depth
8ONGC Mehsana has quietly pushed the closure of its three-year rig earthing GeM bid from 3 December to 10 December 2025 without touching EMD, PBG or LD.
8The move comes on a technically dense, safety-critical scope that demands 24/7 support across drilling and workover rig movements.
8What this extra week does to bidder appetite, pricing discipline and the asset’s broader outsourcing playbook is where the real story now lies.
 
2) Bid window for HDPE pipe and fittings CBM package stretched to 10 December as Prabha Energy keeps securities and LDs unchanged
8Prabha Energy has quietly added 21 days to the bidding calendar for its North Karanpura CBM HDPE pipe and fittings tender without touching EMD, PBG or bid validity.
8The move comes after a Schedule-III clean-up that tightened SDR-11 compatibility and metricised key fittings, increasing the engineering workload on bidders.
8What this longer runway does to participation, pricing discipline and the balance between mill-backed suppliers and traders is where the story really begins.
 
3) Seven-day bid extension tests new rig-vintage flexibility in Odisha Mahanadi charter hire
8Oil India has quietly pushed the bid closing for its Odisha Mahanadi 1400 HP rig charter by seven days after earlier insisting no extensions would be entertained.
8The move lands just after a sweeping relaxation of rig-vintage norms and the insertion of a 25 percent option clause, without any change to stiff EMD and performance security locks.
8Whether this short reprieve deepens competition or merely compresses the execution calendar is what bidders — and the basin’s drilling schedule — will now reveal.
 
4) HPWBM 40-well mud services tender gets 34-day time relief as OIL India weighs bidder depth against strict security regime
8Oil India has quietly shifted the bid closing for its four-year HPWBM mud services tender from mid-November to 18 December 2025.
8The extension comes without any visible softening of a stiff Rs 2.86 crore EMD, 3% performance security for 52 months or a 25% option clause on quantity and duration.
8What this extra month does to bidder appetite, pricing strategy and OIL’s long-term HPWBM partnering options is the real story sitting behind the new calendar.
