Through two acquisitions in April 2010, Apache significantly increased its production assets in the Gulf's shallow waters and deepwater. These acquisitions were prior to BP's Gulf spill, which has the potential of inviting heavier federal regulation and higher safety precaution costs. Gulf operations are also vulnerable to damages and closure due to seasonal storms. However, Apache is well-diversified; no production area accounted for more than 26% of its 2009 production revenues.
