Davy Jones was so eager to cough up its bounty from a massive high-quality reservoir 200 feet thick that McMoran several months ago had to control the flow by filling the hole heavy drilling mud.

Right now, the company says, it has removed that mud from the hole, but it believes that barite from the oil-based mud has blocked the flow.

Normally, when a well begins to flow, the release of pressure cleans up the well bore of contaminants and other debris in the hole during the first few hours it is opened up.
