Aug 2 (Reuters) - Stone Energy Corp posted a third consecutive estimate-beating quarterly profit helped by higher production, and the gas focused exploration and production company backed its full-year output forecast.

Revenue rose 41 percent to $231.9 million, while production rose 6 percent.

Analysts, on average, expected the Lafayette, Louisiana-based company to post earnings of $1.00 a share, on revenue of $212.5 million, according to Thomson Reuters I/B/E/S.

The company also backed its full-year output forecast of 205-225 million cubic feet equivalent per day.

Separately, Stone's larger peer Exco Resources posted second-quarter earnings in line with the estimates.
