Definitions

  • Table 3 [0070] A second group of primary emulsifiers was evaluated at 350°F. The preparation and testing of the muds was similar to the procedure above with the following changes or additions: organophilic Clay will be changed from Bentone 150 to Bentone 38 for thermal stability; the aqueous brine was calcium bromide (54%). Test muds for higher temperature testing are summarized below in Table 4.
  • the sample was subjected to hot rolling for 16 hours in aging cells at a temperature of 35O°F, with the cells pressurized to 250 psi. After the hot rolling process, the samples were allowed to cool, poured into a sample cup, and remixed for 15 minutes. Rheology and ES measurements were then taken again at 150°F, with an ES value exceeding 600 considered desirable after hot rolling. Additionally, the fluid loss and filter cake were evaluated under high-temperature, high-pressure (HTHP) conditions. These testing procedures provide valuable information on the rheological properties, electrical stability, fluid loss, and filter cake formation of the Oil-Based Drilling Fluid samples. Table 10
