NEW YORK, Aug 21 (Reuters) - U.S. energy firms added two oil
rigs this week, the fifth week of increases in a row, after U.S.
crude prices have fallen about a third from recent highs, data
showed on Friday, a sign drillers remain undeterred by low
prices.
Reflecting plans announced in May and June, when U.S. crude
futures CLc1 averaged $60 a barrel, drillers added two oil
rigs in the week ended Aug. 21, bringing the total count up to
674, the highest since early May, oil services company Baker
