Schlumberger Limited announced that it does not intend to extend the pending agreement to acquire a minority equity interest in Eurasia Drilling Company Limited, once the current extension expires on September 30, 2015. The Company will instead focus on other M&A opportunities.

Amidst the gloomy days of August when Brent Crude bottomed out at $42/bbl, the acquisition of Cameron by Schlumberger ($14.8 billion) took place as one of the largest mergers in the oil patch, following the tie-up of Halliburton and Baker Hughes ($32 billion) in November 2014. This consolidation has resulted in an integrated service & equipment provider covering the full oil & gas lifecycle from reservoir to first flow.

Issues have emerged in Russia that could delay or prevent Schlumberger Limited. (NYSE:SLB) from closing a deal with Eurasia. Earlier this year, Schlumberger made a $1.7 billion offer to take a stake in Eurasia, also expressing willingness to acquire the rest of the company. Eurasia is Russia’s largest oil-services company. However, as it turns out, Russia’s Federal Security Service, also known as FSB, is expressing some reservations over the deal.

HOUSTON, August 26, 2015—Schlumberger Limited (NYSE: SLB) and Cameron (NYSE: CAM) today jointly announced a definitive merger agreement in which the companies will combine in a stock and cash transaction. The agreement was unanimously approved by the boards of directors of both companies.

Russia’s Federal Security Service, the main successor to the KGB, is holding up Schlumberger Ltd.’s acquisition of a 46 percent stake in Eurasia Drilling Co., according to two people with knowledge of the matter.

Accenture (NYSE: ACN) has entered into an agreement to acquire Schlumberger Business Consulting (SBC), the management consulting unit of Schlumberger, a global leader in oilfield services.
