The supplied family TDS contains a general preparation section that refers to a polymer eductor or dry-powder feeder. It does not provide a separate inversion or make-down procedure for EC8050 and EA5620 emulsions. Do not automatically apply powder preparation instructions to the emulsion grades; obtain the current grade-specific emulsion procedure before commissioning.

• Potential fit for the defined partially hydrolyzed polyacrylamide emulsion for reactive shale duty after representative testing
• Very-high-molecular-weight PHPA emulsion format for liquid handling and metering
• High-charge classification stated for both EC8050 and EA5620 in the supplied TDS
• PHPA-family compatibility claim covering biopolymers, PAC, and CMC, subject to formulation testing
• Factory-direct documentation, sample screening, order coordination, and export support

1. Characterize the formation and baseline mud, including shale reactivity, salinity, hardness, pH, solids, and temperature.
2. Screen EC8050 and EA5620 at several active-polymer doses without assuming the two TDS-listed grades have different application roles.
3. Compare hot-rolling recovery, cuttings integrity, dispersion, rheology, fluid loss, and lubricity against an untreated control.
4. Repeat the preferred condition with the actual KCl, PAC, CMC, biopolymer, weighting material, and contamination expected in the field.
5. Run a controlled field trial and trend dilution, solids-control load, cavings, torque, drag, and mud properties before changing the treatment program.

• Confirm the selected grade, current specification, order limits, and documentation before production.
• Screen EC8050 and EA5620 with representative fluids because the supplied family TDS does not assign different application roles to the two grades.
• Record water chemistry, temperature, shear history, mixing sequence, and baseline fluid properties during laboratory work.
• Scale up only after agreed performance indicators and operating limits are demonstrated under representative conditions.
