The U.S. Department of Justice has cleared without conditions the proposed merger between Schlumberger Ltd. and Cameron International Corp. The world’s largest oilfield services operator and Houston-based Cameron agreed to a $14.8 billion deal last summer that would combine complementary technology portfolios (see Shale Daily, Aug. 27). Completing the merger, expected in early 2016, requires approval by Cameron stockholders; the vote is scheduled Dec. 17. Schlumberger also said it has acquired Tulsa-based Fluid Inclusion Technologies Inc., an oilfield service company that specializes in laboratory analysis of trapped fluids in rock material and advanced borehole gas analysis on drilling wells.
