premise: OSLO, Oct 13 (Reuters) - Norway’s Statoil has sold a 15.5 percent stake in the Azeri gas project Shah Deniz to Malaysia’s Petronas for $2.25 billion, the latest asset the firm is selling to protect its cash flow and returns to shareholders. The deal also includes Statoil’s stake in the pipeline carrying gas to markets and two related companies. Its second-quarter production from the Shah Deniz field was 38,000 barrels oil equivalent per day, it said. (Reporting by Gwladys Fouche, editing by Terje Solsvik)
hypothesis: Statoil's sale to Petronas had an effect on their second-quarter production
reason: While this is very likely correct, there is nothing that makes it a certainty.
