Clay swelling, Linear Swell Meter, Inhibition, Nano-particles
Clay swelling is considered to be a main cause for the formation damage in oil and gas reservoirs. There for using of non-inhibitive drilling fluids to drill shale formations usually results in wellbore instability problems. Shale cuttings consisting of different montomorillonite content were collected from different core samples. They were evaluated using X-ray diffraction (XRD), X-ray fluorescence (XRF) andcation exchange capacity (CEC) using Methylene Blue (MB), hence classified into Shale A, B and C.Swelling index of the shale measured using compressed disks of shale in contact with OCMA bentonite for 20 hrs using Linear Swell Meter (LSM).Inorganic salts in term of potassium chloride (KCl) and nanoscale oxides in terms of ZnO, TiO2 and SiO2 used as inhibitor of shale swelling. The inhibitors are added to OCMA bentonite as well. Swelling of the shale cuttings increased in the order: Shale A
