UPDATE 1-Oil States Q1 net profit drops

* Q1 EPS $1.13 vs $1.29 a year ago

* Q1 revenue rises 11 pct

May 7 (Reuters) - Oil and gas services provider Oil States International Inc (OIS.N) posted a 14 percent decline in first-quarter earnings, hurt in part by a significant drop in drilling and completion activity in North America.

In the latest quarter, the company posted a net income of $56.1 million, or $1.13 a share, compared with $65.5 million, or $1.29 a share, a year ago.

Revenue for the quarter rose 11 percent to $667.1 million, with a small rise in revenue from the offshore products and tubular services segment, helping offset a 13 percent decline in its well site services segment.

Analysts, on average, were looking for earnings $1.04 a share, before items, on revenue of $650.7 million, according to Reuters Estimates.

Shares of the Houston-based company closed at $20.54 Thursday on the New York Stock Exchange. (Reporting by Antonita Madonna Devotta in Bangalore, Editing by Dinesh Nair)
