| Content Summary | well integrity. Rheological and fluid loss characteristics are key fluid properties that need to be optimized for the development of stable and “smart” water-based fluids. The objective of this research is to develop appropriate additives in order to reduce formation damage in drilling operations. We do this by examining the fluid loss characteristics for water-based muds, utilizing iron oxide nanoparticles as fluid loss additives. The nanoparticles benefit from their small size and it is anticipated to seal porous and/or fractured formations and thus are expected to provide a great potential for reduction of formation damage. We present API filtrate loss and filter cake characterization along with the changes in the rheological properties of drilling fluids containing various concentrations of nanoparticles. We have measured rheological properties with Couette type viscometer both at low and high temperatures. LPLT and HPHT API filter presses have been used for fluid loss measurements. Scanning Electron Microscope (SEM) pictures were used to analyze the nanoparticle size range and to reveal secrets of their good performance by providing deep insights for their microstructure, the interfacial phenomena and the interaction between bentonite particles and the nanoparticles. The examined nanoparticles have the potential not only to significantly reduce the fluid loss and develop a thin mudcake, but also to maintain optimal rheological properties thus providing effective pressure control. The required relatively low concentration in the drilling fluid provides a base for more efficient, environmental friendly and safer drilling practices. | en |
