09:11 AM EST, 02/25/2025 (MT Newswires) -- Schlumberger ( SLB ) said Tuesday it has met US antitrust requirements for its planned acquisition of ChampionX ( CHX ) , as waiting periods under the Hart-Scott-Rodino Act have expired.

The company said it has agreed to sell ChampionX's ( CHX ) ownership in US Synthetic Corporation to a third-party buyer, while it will retain its MegaDiamond operations.

The acquisition still faces regulatory scrutiny in other regions, including a Phase II review by Norway's competition authority, Schlumberger ( SLB ) said.

The company added it now expects the deal to close by the end of Q1 or in early Q2, depending on the outcome of the remaining reviews.
