* Q1 loss 3 cents per share vs expected profit
* Revs down 34 pct at $931.5 mln, above Wall St estimates
* Baker Hughes takeover expected to close this quarter
SAN FRANCISCO, Feb 8 (Reuters) - BJ Services Co (BJS.N) posted an unexpected quarterly loss as revenue fell 34 percent, but reported generally stable to slightly improved pricing in North America for its key oilfield pressure-pumping operation.
The company is in the process of being taken over by Baker Hughes Inc BHI.N, which still expects to close the $6 billion deal this quarter.
For its fiscal first quarter ending in December, Houston-based BJ Services reported a loss from continuing operations of $8.4 million, or 3 cents per share, as revenue fell 34 percent to $931.5 million.
Analysts on average had been looking for a profit of 4 cents per share on revenue of $898 million, according to Thomson Reuters I/B/E/S.
The takeover of BJ Services will mark a return to its previous owner. Founded by Byron Jackson in California in the 1870s, BJ ended up as part of Baker Hughes through a series of deals a century later, before being spun out in 1990. (Reporting by Braden Reddall; Editing by Gary Hill)
