Socar said on Monday a large gas leak at one of the wells during maintenance caused a fire. All 49 workers had been evacuated from the platform. No casualties were reported.
"The gas leakage was stopped and a fire was completely extinguished in early hours on Tuesday," Socar and the country's Emergency Ministry said in a joint statement.
In December last year, 30 workers were killed on one of Socar's offshore rigs during a large storm.
