Recently, ZPEC successfully passed British Petroleum (BP) drilling pre-qualification, becoming only the second Chinese company to pass this pre-qualification, the first being CNPC.

BP, the third-largest energy company and fourth-largest company in the world, is well known for its high standards in the global oil and gas industry.  Both BP and Saudi Aramco employ the strictest and most difficult drilling pre-qualification requirements in the world.  Once you pass their pre-qualification that means you step into the highest standard class in the oil and gas industry.
