Jan 29 (Reuters) - Britain's competition regulator said on Wednesday it has launched an inquiry into oilfield services company SLB's SLB.N proposed $8 billion deal to buy smaller rival ChampionX CHX.O.
The Competition and Markets Authority said it is looking at whether the deal, which was announced in last April, would raise competition concerns in any UK markets.
It has set a deadline of March 27 for its Phase 1 decision.
