How the oil spill changed businesses on the Gulf Coast.

BP has long complained that its settlement money for the Deepwater Horizon spill was often spent frivolously.

The company's $20 billion Gulf oil spill compensation fund is almost empty — and there could be many more claims in the pipeline.

Halliburton and BP work together in the oil fields, despite disagreements over fault in the BP oil spill.

Halliburton will pay a $200,000 penalty, but says it will not face any criminal prosecution for the act.

Last week, BP and five coastal states affected by the Deepwater Horizon spill announced $594 million in projects funded by BP for early restoration of the Gulf. A lot of the money is being spent on stuff not related to the spill at all, especially on repairing damage from various hurricanes.
