Abstract: This research aims to design drilling muds using different polymers and nano filler for a certain section in Al-Halffia oilfield in Maysan Government (Iraq) and study their properties. Carboxymethyl Cellulose (CMC), Poly Vinyl Alcohol (PVA) and Superabsorbent Polymer (SAP) were added in five ratios (1, 1.6, 2.1, 2.6, 3.2 wt. %) individually. Silica Nano Particle (SNP) was added to the best formula in five ratios (1, 2, 3, 4, 5 wt. %). Properties of drilling muds such as gel strength, density, viscosity, filtration and alkalinity were studied. Results showed that the PVA addition causes fluctuation in filtration and viscosity properties and decreasing in PH values, while the density remain constant approximately. SAP addition causes sharp decreasing in the filtration ability and increasing in viscosity, alkalinity and density. CMC addition causes the same behavior as SAP effect but with little decrease in filter loss and increasing in gel strength property. From the optimization view point, CMC with 2.1 wt% seems to be the best formula for the certain section of Al-Halffia oilfield. The addition of SNP to the best formula increased the filtration and the alkalinity, while viscosity and density sever from fluctuations.
