This study introduces a combined barite-ilmenite weighting material to prevent the barite sag problem in water-based drilling fluid. Different drilling fluid samples were prepared by adding different percentages of ilmenite 25, 50, and 75 wt. from the total weight of the weighting agent to the base drilling fluid barite-weighted.
narrow-mud-weight drilling windows, for instance, programming rheological properties sufficiently low to properly manage equivalent circulating densities ECD, yet high enough to minimize barite sag and still maintain proper hole cleaning, is particularly problematic. The inherent problems with conventional weighting agents also are magnified
increased bottomhole pressure, mud losses and formation damage, and can ultimately lead to the loss of the well. In todays high-angle wells, barite sag is a well recognized phenomenon. Barite sag occurs due to settling of the weighting agent when circulation is stopped and results in undesirable fluctuations in mud weights3. This can cause ...
Drilling Industry The overwhelming majority of the barite that is mined is used by the petroleum industry as a weighting material in the formulation of drilling mud. Barite increases the hydrostatic pressure of the drilling mud allowing it to compensate for high-pressure zones experienced during drilling.
