Haliburton and Cameron were contracted for this well by BP (the former often used by them for over half a century.
The subcontractors follow specifications laid down by the operating company. It seems BP did not require the most advanced methods offered by Cameron.

I don't know about Cameron, but Haliburton has offered careful service by excellent technicians to many companies over their long history. The BP executive may live to regret his comments to the Congressional Committee; he cannot be sued, however, because comments to a legislative body by are not actionable. I am sure that he will not repeat the remark outside of a protected 'venue'.
