What Roc Oil does

Roc Oil is an Australian-headquartered independent upstream oil and gas company operating across the full E&P lifecycle: exploration, appraisal, development, and production. Its business is organized around working interests and operatorship roles in producing and development assets across four regions — China (Beibu Gulf, Pearl River Mouth Basin, Sichuan Basin), Malaysia (Sarawak offshore), Oman (Blocks 3&4, 49, 56, 58), and Australia (historical). The company holds 100% operatorship at the onshore Bajiaochang tight gas field in Sichuan and at Oman's Blocks 49 and 58, and operates Weizhou 10-3W (35%), Huizhou 12-7 (50%), and Block 56 (65%); in other assets it serves as a non-operating working-interest partner and, in D35/D21/J4 offshore Sarawak, as project development manager.

The company's underlying technology comprises specialized offshore marginal oil field development solutions, patented well-seismic integration modeling (CNIPA National Invention Patent for a method using Drilling Index Dx), proprietary economic evaluation and sedimentary facies prediction systems, and an eight-element HSE Management System with full lifecycle Asset Integrity Management. These capabilities support drilling accuracy, reservoir identification, and mature-field redevelopment that has repeatedly out-performed plan (e.g., WZ12-8W/6-12 at 2.28x ODP target, BJC gas production up ~396% under ROC operatorship since 2021).

Roc Oil generates revenue from sales of crude oil, natural gas, and associated petroleum products derived from its operated and non-operated working interests, with revenue allocation determined by PSC terms with NOC partners. It monetizes assets by acquiring producing and near-term development properties, providing operator or project development manager services to NOC partners, and reinvesting in exploration and brownfield redevelopment. Since 2019 the company has operated as a wholly-owned subsidiary of Hainan Mining Co. Ltd (itself controlled by Fosun International) following the 2024 acquisition of Tethys Oil AB, which added Omani acreage and materially expanded the production and reserve base.

Revenue model

1. Oil and Gas Production Sales: ROC generates revenue primarily through the sale of produced crude oil, natural gas, and associated petroleum products from its operated and non-operated working interests across China, Malaysia, and Oman.
2. Joint Venture Working Interest Revenue: As a working interest partner (ranging from 19.6% to 100%) in producing assets with NOC partners (CNOOC, PetroChina, PETRONAS), ROC receives production allocation proportional to its equity stake in each joint venture.
