I think some of the inventory build may be due to striking union employees at mutiple refineries. I understand your point about the inventory build but over the last 2 weeks or so this news can't seem to drop WTI below $48.50/49 or so.
I am expecting to see more drillers run into tighter lending in the coming months. I expect some to go bankrupt. Lenders have to be nervous over the rapid decline in oil prices. Less Cap X. Less production. I don't expect to see WTI at $44 again unless we go into an economic recession.
