8HDPE slipped Rs 0.5/kg this week on a mild adjustment from early-month levels. 

1) Adhul Marketo faces tight inventory and delivery discipline in ONGC’s frontier-basin industrial gas tender for rigs E-2000-8 and E-2000-6.
8ONGC’s GeM tender for industrial gases at Samastipur and Ballia rigs looks small on paper but pushes a heavy load of inventory and delivery risk onto the supplier.
8With no guaranteed volumes, capped free rentals and termination triggers for refusal or repeated quality slips, bidders like Adhul Marketo India Private Limited are effectively underwriting ONGC’s just-in-time cylinder strategy.
8The real question is which risk lever—option quantity, LD, or legal silence on disputes—ends up defining pricing and participation in the next round.
 
2) Five civil contractors face firm-price, compliance-heavy three-year ARC for rig deployment works in ONGC Cambay Asset.
8ONGC’s Cambay civil-works ARC has drawn five regional contractors into a three-year, multi-site race with no publicly visible relaxations on risk or security.
8The tender architecture locks in firm prices, extended PBG validity and tight documentation demands, while promising quick payment only to those who can navigate the paperwork flawlessly.
8How these bidders balance that risk stack against aggressive pricing will decide who emerges as a long-term civil partner around Cambay’s workover rigs.
 
3) Corrigendum package resets bid security, tie-breakers and force majeure for Ahmedabad fire protection LSTK.
8ONGC’s latest corrigendum does far more than tidy up pre-bid dates for its Ahmedabad fire-protection LSTK.
8It rewires who wins in an L1 tie, who must lock up bank limits for how long, and when either side can walk away from a force-majeure-hit contract.
8Whether this tougher but more structured playbook broadens the bidder pool or quietly filters it down will only be visible when the final techno-commercial shortlist emerges.
 
4) Nine-day GeM deadline extension keeps ONGC heavy electrical machines repair RC for offshore drilling rigs open until 18 December 2025.
8ONGC has quietly pushed out the closing date on its three-year repair RC for rig-critical electrical machines without touching a single technical or commercial safeguard.
8Bidders now have nine extra days to align demanding workshop-facility proofs, calibration certificates and Make in India paperwork.
8Whether that small shift broadens a niche vendor pool or merely delays a tight contest is what this extension will now test.
 
5) Third bid-date extension and tougher group guarantees reset the risk calculus for the Dandewala gas sweetening unit.
8OIL has quietly pushed the Dandewala membrane-GSU tender out to 24 December while overhauling who can bid and how they must backstop performance.
8Experience windows, support-company rules, moisture specs and O&M securities all look different from the early September issue.
8How bidders price a wider entry gate against harder long-tail obligations will decide who still stays in this race.
