12:31 (Dow Jones) BP shares holding their ground following news of snag with containment process, which dramatically reduces -- at least temporarily -- the amount of oil the company is able to collect from the leaking well on the floor of the Gulf of Mexico. News comes as responders face the prospect of tropical storm disrupting their efforts next week. Expect investor attention, which has been trained on the political drama surrounding BP and the offshore drilling moratorium, to once again focus on spill response progress in the coming weeks. BP up 8c at $29.79 in New York.
