<br/>After nearly three months of more misses than hits, British Petroleum said it has managed to plug the well that was gushing oil into the Gulf of Mexico.<br/><br/>BP Senior Vice President Kent Wells told a press conference that the company will be consulting with scientists and government officials every six hours to assess if the test was working.<br/><br/>With several failed attempts in the past to stop the leakage, President Barack Obama has been cautious about his assessment of the latest development.<br/><br/>He termed it as a positive sign but said it is still in the testing phase.<br/><br/>Despite the initial success in tamping down the oil flow, no-one is giving the all clear signal just yet and the testing for oil pressure will continue for two days.<br/><br/>Louisiana Governor Bobby Jindall, whose state is among the five gulf states to be hit by the leak, said that he is cautiously optimistic as the test proceeds.<br/><br/>The test, if successful, will prevent further pollution into the Gulf of Mexico even as millions of litres of crude oil continues to float in a thick layer over its waters.
