Engineers and scientists have intensified monitoring of the well, poring over images and data collected by robots, sonar scans, and seismic and acoustic examinations. A government ship is in the area, fitted with equipment for detecting methane gas, which would be an indication of a leak.
Apart from the hand-wringing, there are probably dozens of scientist and petroleum engineers intensely focused on this effort. Investigations into the cause of the disaster and how it could have been prevented will probably point out that the desire to save money and maximize profits trumped any investment in safety that sound engineering could have provided. They are literally changing textbooks in colleges as to how we'll deal with this in the future (hopefully).
