CNPC Greatwall Drilling

CNPC GWDC is leading petroleum drilling service company in China. We provide all kinds of service for the well bore, like drilling rig, drilling fluid, mud logging, directional drilling, wireline logging, workover, energy development.... Without facing the technical barrier, the long tools delivery period and the poor after sale service, being a manufacture is an important advantage for a drilling service contractor.We make MWD and LWD tools with international standard quality but lower price then other companies. The tools have been tested and widely applied in China and overseas work. We have a independent PDC bit plant, located in the northeast part of China. The productivity is 3000 PDC bit per year. We work together with NOV bit. Now our bits serve CUPET in Cuba, CNPCNC in Noger, Andes in Ecuador, and so on.
