ADNOC takes final investment decision on Ruwais Diyab unconventional gas development

ADNOC announced at ADIPEC on 2 November 2026 that it has taken a final investment decision (FID) on the Ruwais Diyab Unconventional Gas Development in Abu Dhabi, its first large-scale unconventional gas development.

The project will deliver 345 million standard cubic feet per day (mmscfd) of raw gas from 2029 over 25 years, with potential to reach up to 1 billion scfd. The gas will be processed on site and connected to the UAE gas network through new pipeline infrastructure. ADNOC said the development is delivered by ADNOC Onshore under a design-build-operate (DBO) model.

ADNOC’s release did not name a contractor or give the investment value. Watch for the contractor and contract value for the DBO scope, the drilling programme and the new pipelines.
