oil price changes related to the political upheavals in Libya will probably be short-lived. Whatever gov't establishes control will be compelled to re-establish oil production as quickly as possible.
Most of the oil production is in areas very remote to where the violence is and at the moment i suspect those workers are probably in greater danger during transit to and through the coastal cities as opposed to being in danger at the well sites. I suspect the contractor and production companies are more worried about the development of hostage situations and inability to perform due to supply problems.
