At first oil price plunged with the 4.7 million barrel increase. But, the numbers showed that refineries operated at 92.8%, lower than last week, AND, that the US field production decreased again, which is the most important part of the report imo.
US production peeked at the beginning of June and never stopped to decrease since then. This trend will be more and more confirmed in the coming months, imo.
