Full textAbstract
From energy management viewpoint, optimum well drilling has been considered a serious demand to make maximum profit under minimum cost and highest safety for oil and gas companies. For reaching these goals, the drilling fluid as a most important part of the process has been targeted to be modified into a smart fluid using new additives. Since nano-technology has made a drastic revolution in characteristic of materials. in this study, it has been used to make an optimum drilling fluid including appropriate properties for dealing with diverse well problems like fluid loss and improvement of rheological properties. In addition to study the effectiveness of a Bio Polymer - Surfactant fluid blends, containing Nanoparticles as fluid loss additives have been presented to show their effectiveness in reducing the filtrate losses to the formation by forming a thin, non-erodible filter cake. Laboratory experiments were carried out for the different combination of polymer and surfactant to find the optimum of fluid performance. The laboratory measurements included measuring mud weight, pH, viscosity, gel strength and standard API filter press. Results show that sized silica nanoparticles can be used instead as a bridging agent. The nanoparticles play an important role in reducing the fluid loss.
