BP was set to continue reviewing testing procedures

he oil giant had expected the tests -- to check pressure in the well and determine if it can be sealed once and for all -- to get under way Tuesday afternoon.

But Tuesday night, BP announced that additional analysis of the well testing procedure was needed. The move followed a meeting with Energy Secretary Steven Chu and his team of advisers.

A source informed about BP operations told CNN's John King that, "There were some potential complications that might cause a delay -- some bad, some in the 'better to be safe than sorry' category."

CNN's David Mattingly, who accompanied the U.S. Coast Guard out to a site over the ruptured well Tuesday, said Wednesday a "small city of vessels" remains at the site and continues combating the sheen of oil in Gulf waters as smoke from burning gas and oil hovers on the horizon.
