Shams Al-Shomoos Oil Refining Company
Shams Al-Shomoos Oil Refining Company (Private Joint Stock) was established in 2025 by the private sector with the aim of investing in upstream oil and gas drilling and extraction industries, as well as downstream refining and petrochemical industries. The company seeks to leverage the country’s strong market and product development potential to create opportunities for the active participation of producers in the downstream oil industry, both in the short and long term.
Following field assessments, expert evaluations, and comparative studies at the regional and national levels, and after reviewing dozens of proposed plans and projects, the construction of a condensate and crude oil refinery in Oman’s AlDuqm Free Zone was ultimately approved.
