ONGC’s EOI ONGC/ Sacrificial Stinger /EOI/2026/13, issued on 9 October 2026, seeks suppliers’ technical information for selected Mumbai High wells. The proposed fiberglass string is non-metallic and drillable, intended to place cement near loss zones during lost-circulation plug or cement-squeeze operations. Indicative pilot lengths are 800 m at 2⅜ inches and 1,200 m at 3½ inches, with compatible drill-pipe connections; these are not confirmed orders.
Responses are due by email on 29 October 2026, with no closing time or time zone stated. Suppliers are asked about load ratings, pressure, temperature, fluid compatibility and retrieval or drill-out limitations. This is solely market exploration, not a commercial tender or RFP, and creates no procurement commitment. Specific wells, their fluids, contract value and bid security are not identified.
Libya’s AGOCO lists electrical connection works at five named wells. The 25 October 2026 bid deadline follows a booklet collection period that has already ended.
