E&P contracting brief: Part I – 3 Dec 2025

1) Mud agitator gearbox refurbishment tender packs one year warranty and tight 60 day schedule — ONGC Sagar Ratna8ONGC’s Sagar Ratna team has moved a small but critical mud agitator gearbox refurbishment into a tightly scripted, invitation-only tender.

Behind the simple scope sit aggressive timelines, a one-year warranty and liquidated damages that can claw back up to 10% of contract value.

What this structure does to bidder appetite, pricing and long-term rig reliability is not fully visible from the NIT alone.

2) ONGC seeks single-stack GST, e-invoice and litigation backbone for shared finance services8ONGC’s new GST compliance management tender quietly turns a routine tax job into a full-stack digital backbone linked to SAP, IMS and GSTN.

The same platform will also track every notice, refund and contingent liability across 53 registrations while sitting under strict uptime and security expectations.

What this contract really decides is how much risk and control ONGC is prepared to centralise in one vendor for three years.

3) Oil India Rajasthan field raises the bar for thermal well premium casing connections with a high-spec empanelment EOI8Oil India Rajasthan field has moved the contest for premium casing connections into a pure technical arena, leaving price for another day.

Only those designs that have survived ISO/PAS 12835 thermal cycling at more than 320 °C and 11,000 kPa, and can document real CSS or SAGD field performance, will make the first cut.

What remains unclear is how many new connections OIL actually wants on its panel and how that choice will reshape future drilling campaigns in Baghewala and beyond.

4) Priserve edges out tightly bunched rivals to clinch ONGC Mumbai communication services O&M award8ONGC’s three-year Mumbai communication services tender has closed with just 0.7% separating the top three bidders, but an 81–289% jump to the rest of the field.

The corporation has simultaneously shifted to contractor-friendly monthly payments while tightening non-performance deductions and availability metrics.

Whether Priserve’s razor-thin L1 can withstand ONGC’s high-stakes uptime regime will only become clear once the new contract hits the offshore field.
