Formulación de lodo silicato en sección de 16'' : diseño en base silicato para la sección de 16'' usando como modificador reológico la goma xanthan.

Abstract

In this research, the formulation of a drilling fluid using sodium silicate as an inhibiting additive instead of commonly used calcium nitrate was evaluated in the 16'' section. Various laboratory tests were conducted to study how sodium silicate affects the fluid's properties, particularly its inhibiting capacity. Additionally, variations in the concentrations of bentonite in the drilling fluid were performed to study their impact on the mud's properties. These variations allowed for determining the optimal bentonite concentration, providing suitable viscosity and good inhibiting capacity without compromising the fluid's performance in the well. Also, thanks to the different concentrations of sodium silicate evaluated in each bentonite variation, it was observed that sodium silicate significantly contributes to the viscosity and flocculation of the drilling fluid. The comprehensive approach of this research, evaluating both sodium silicate and bentonite, provided valuable information for formulating and optimizing drilling fluids. The findings offer a deeper understanding of how these additives affect the fluid's behavior and performance within the 16'' surface section.
