A group of dealmakers saw the upside of sunken oil prices yet again on Wednesday, when international oil services juggernaut Schlumberger Ltd. announced that it would acquire smaller rival Cameron International for $14.8 billion.

Baker Botts is serving as lead legal counsel for Schlumberger. Gibson, Dunn & Crutcher, which saw a surge in deal work announced this week, is advising on antitrust matters. Cravath, Swaine & Moore is representing Cameron in the deal, which is expected to close in the first quarter of next year.
