xc polymers in drilling mud

Recognizing filter cake properties for the right choice of drilling fluids, which decreases bore difficulties like formation damage is very essential. correctly knowing the properties of filter cake provides the effective management of the hydrocarbon producing process. this research aims to practically investigate the effect of different concentrations of xc polymer on filter cake properties, materials destroyed due to filtering, and formation damage for choosing optimum concentration of xc polymer. high-pressure high-temperature (hpht) filter, which was compressed by a ceramic plate was used for flow direction in this study. seven samples of water-based drillings were used. these filter cake chemical compounds were investigated by scanning electron microscope (sem) descriptor.the results show that the optimum concentration of xc polymer in this study was 1.0 lb/bbl (1 g/350 ml). also, it was observed that 1.0 g xc polymer per 350ml of the drilling fluid is suitable for the proper application of the optimum material deformation. if more than 2.0 g of xc polymer is added, the fluid loses its properties and becomes almost motionless. therefore, 1.0 g concentration of xc polymer causes less diffusion reduction of ceramic plate. at these concentrations, less reduction in ceramic plate diffusion and sound filter cake properties were observed. besides, it's an identifier for fewer formation damages at this concentration of xc polymer. this research intends to collect keywords and required concepts based on the series for a more tangible understanding of the subject. these will be examined in the following sections.
