This paper reports on the appearance of fluid-loss polymers in freeze-dried drilling-mud filter cakes that was studied with scanning-electron-microscope (SEM) photography. Three fluid-loss polymers were studied: starch, polyanionic cellulose (PAC), and a high-temperature-(HT)-stable, sulfonate polymer. The effects of electrolyte contamination (NaCl, CaCl{sub 2}, and MgCl{sub 2}) and temperature (200 to 350{degrees} F) on the appearance of the fluid-loss polymers were also studied. A correlation between API filtrate and polymer appearance was sought.
