Halliburton profit soars 83% in Q2 --Before the explosion of the Deepwater Horizon rig on April 20, Halliburton was hired by BP to seal the Macondo well before it blew up. 19 Jul 2010 US oil giant Halliburton says its second-quarter profit has jumped 83 percent, despite because of the company's involvement in the Gulf of Mexico oil spill volcano. The news caused Halliburton shares to soar 5 percent to $28.89 in Wall Street pre-opening trade on Monday, the Associated Press reported. The oil giant's net income for the April-June period was $480 million up from $262 million one year ago.
