Repsol unveils ARiA, its AI‑driven digital brain to optimize refining and create new digital services

Executive summary: Repsol announced the launch of ARiA, its digital brain that uses AI to monitor and optimize refinery processes and to develop new AI‑based services. The initiative shows how a major oil firm is leveraging AI to cut costs, reduce emissions and generate new revenue, signalling wider AI adoption in the hydrocarbon sector.

Who is involved: Repsol’s executive leadership and its internal AI development team are behind ARiA; no external partners were disclosed in the announcement.

Likely next: Repsol will pilot ARiA at the Cartagena refinery by Q4 2026, evaluate a rollout to other sites, and explore monetizing the platform as a service to third‑party energy firms.

Repsol has introduced ARiA, a centralized artificial intelligence platform intended to improve refinery efficiency, lower operating costs and open AI‑as‑a‑service offerings. The move reflects a broader trend of traditional energy companies embedding AI into core operations to stay competitive amid the energy transition.
