E&P contracting brief: Part II – 13 Oct 2025

1) IGST concessional rate lifted to 18% and bid dates moved to mid-October — ONGC/cement bulk handling plant, Shertha8ONGC has pushed the bid calendar to 14/15 October 2025 and locked the EMD at Rs 2,03,000.

The concessional import/GST clause is reset to 18% with a merit-rate escape where legitimately lower.

Pricing power will now come from documentation strength and O&M reliability, not headline discounts.

2) IGST anchor lifted to 18% with merit-rate fallback; anti-profiteering undertaking flagged — ONGC/Assam Asset crude oil tanker ARC8ONGC has rewritten ITB 13.0 to embed the 18% IGST baseline for List-33 petroleum-operations imports while preserving a lower merit rate where applicable.

An anti-profiteering/ITC pass-through undertaking tightens pricing discipline at source.

With the calendar and securities unchanged, competition will tilt toward documentation-strong bidders who can defend both tax treatment and on-ground logistics.

3) Bid due-date pushed to 28 October for WON Basin IT stack — ONGC8ONGC has granted a two-week extension on its air-gapped HCI-plus-storage rebuild for the WON Basin.

The delay widens room for OEM-anchored designs and sharper compliance packs.

What it does to bidder spread, pricing discipline and DR/SIEM alignment will be the real story at opening.

4) Bid due-date moved to 06 November for offshore helicopter charter — ONGC/Mumbai Region8ONGC has pushed its six-helicopter charter deadline by 28 days.

The additional time could widen the OEM/operator pool for IFR and night-ops compliant fleets.

Whether that translates into sharper pricing and stronger availability will be clear only at opening.

5) Bid deadline moved to 17 December for sick-well revival programme — ONGC/Ahmedabad Asset8ONGC has pushed the close to 17 December 2025, realigning field visits, pre-bid queries, and opening into a tighter year-end window.

The extra runway allows bidders to deepen well-wise revival planning and paper complex guarantees without cutting corners.

Whether this widens competition and sharpens revenue-share bids will only be clear at opening.

6) Bid calendar pushed to 06 November 2025 for integrated drilling — OIL/IDS-S Sadiya8OIL has rolled the submission gate to 06 November 2025 while leaving core contract constructs unchanged.

The added 28 days over the last notice and 331 days over the IFB baseline should improve rig/service tie-ups and financing of securities.

Whether that translates into wider participation and keener pricing will surface at opening.
