Aug 22 (Reuters) - Australia's Oil Search Ltd (OSH) on Tuesday said half-year profit soared more than five-fold on higher oil and gas prices and lower costs and said it expects its partners to agree by the end of the year on how to coordinate development of their gas projects in Papua New Guinea.
Net profit rose to $129.1 million for the six months to June from $25.6 million a year ago, in line with three analysts' estimates.
The oil and gas explorer declared an interim dividend of 4 cents a share, up from 1 cent a year ago and in line with analysts' forecasts.
