  • With Chinese oil industry development and drilling fluid technology update in rent years, more and more oilfields are using oil-based drilling fluid, which brings great benefits to drilling engineering, but poses a series of problems at the same time, that is, how to manage the used drilling waste?...
  • Chinese mud technology services are under each drilling company, short of independent and specialized mud technology service companies. Biggest Chinese mud technology service company is Great Wall Drilling Fluid Company, mainly providing drilling fluid, solids control, waste management and other int...
  • Development of drilling fluid system and additives is facing new breakthroughs to adapt to requirements of deep well, ultra deep well and complex formation drilling and increasingly valued environmental requirements, as well as further reduce drilling cost. New treatment agents have to adapt to ultr...
  • The importance attached to unconventional oil and gas resources, especially shale oil and gas development through horizontal well, shows unique advantage of oil-based drilling fluid on shale formation. It is proved that oil-based drilling fluid is the prime choice for shale gas horizontal well const...
  • Recently, the Bozi No. 9 Well of PetroChina Tarim Oilfield Company was successfully tested, and it has obtained high-yield industrial oil and gas flow with a daily natural gas of 418,200 cubic meters and the condensate oil of 115.15 cubic meters. It is another 100-billion cubic meters gas field disc...
  • It is investigated that core products in mud system of the foreign-invested mud companies come from abroad. It is partly because they have their own research development and production base abroad, and further, domestic drilling fluid additives cannot conform to high standards. Low-end products with...
