Introduction

Objective Drilling Fluid used to carry cuttings, cool bit, provide hydrostatic pressure, etc. Loss Circulation is a common drilling problem Drives up project costs, increases non-productive time, etc. Typical LCMs are micro to macro sized and therefore inefficient in tight formations Mixing drilling fluid with nano-sized particles Objective: Investigate the fluid loss of drilling muds mixed with nanoparticles.

Introduction to Nanoparticles Nanomaterials are substances that have at least one dimension smaller than about 100 nm (billionths of a metre). Nanomaterials can be nanoscale is just one dimension (e.g. surface films), two dimensions (e.g. fibers or strands), three dimensions (e.g. tiny particles). Muir, H. (2011). Science in Seconds.

Applications of Nanoparticles in O&G Industry Loss Circulation: The control and prevention of loss circulation by micro and macro based material showed limited success. Pipe Sticking: Produce thinner mud cakes therefore decreasing the probability of a stuck pipe. Potential to reduce the adhesive tendency of mudcakes by forming nano-film on drill string surface. Wellbore Instability: Decrease the exposure of shale to drilling muds, and thus avoid swelling and wellbore instability. Torque and Drag Reduction: Provide reduction of frictional resistance between pipe and borehole via formation of thin lubricating film. Nabhani, N., & Emami, M. (2012).

Literature Review (Zakaria et al., 2012) showed that under LTLP API Standard Test, more than 70% reduction in fluid loss was achieved with NPs compared to only 9% reduction with typical LCMs. (R. Saboori et al., 2012) showed that CMC nanoparticles resulted in desirable reduction of amount of water loss and mud cake thickness in comparison with conventional CMC. (Contreras et al., 2014) showed that under HTHP Filter Press, filtration reduction up to 76% was achieved using NPs mixed with graphite at two different concentrations. Zakaria, M.
