Performance study of nano additive for reducing formation – drilling fluid Interaction, clay swilling, lubrication & friction reducing of drilling operation by pilot scale production in proposed wells condition



National Iranian South Oil Company(NISOC)



Drilling fluid- different layer (especially shale formations ) interaction(water adsorption, osmotic swelling and cation exchange)  in  hydrocarbon reservoirs caused  major problems, such as  well bore instability, bit balling ,  sticking drill strings , are the largest source of trouble, waste of time and over costs during drilling . In this project, the performance of nano additives on reducing formation – drilling fluid interactions, clay swilling, lubrication & friction reducing of drilling operation are investigated; also pilot scale of nano additive in wells condition will be produced.
