Mechanical degradation of polyacrylamide at ultra high
Long-chain PAM acts as a friction reducer, suppressing turbulent vortices and thereby reducing pumping cost. 5,6 Low levels of mechanical chain scission can occur under low strain rates (<10 5 s −1), similar to those encountered during flow through valves, pipes, and the wellbore, decreasing the polymer MW and lowering the degree of drag
High viscosity friction reducer (HVFR) as a completions fluid has been tested in many premier plays in North America, such as the Bakken, Permian and Eagle Ford basins (Van Domelen et al. 2017). Increasing popularity due to production output and operational efficiencies have led to the first trials in the developing STACK play.

- Is polyaluminum chloride a good coagulant for water treatment?
- Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water [ 6 ].
- Is polyaluminium chloride better than polyelectrolyte – alum-based coagulation?
- At the Barekese Water Treatment Plant in Ghana, an alternative, the polyelectrolyte – polyaluminium chloride (PAC) is also used in coagulation but limited information is available on the operating conditions required to achieve better performance than alum-based coagulation.
- Can poly-aluminum chloride and aluminum sulfate treat a partially stabilized leachate?
- This study examined poly-aluminum chloride (PAC) and aluminum sulfate (alum) in treating a partially stabilized leachate, and compared attained results in respect to the removal of chemical oxygen demand (COD), turbidity, color and total suspended solid (TSS).
- Why are aluminium based polymers used in water treatment?
- These shortfalls in the use of alum have led to the synthesis of improved, aluminium-based polymers, which have been used extensively, over the few last decades, for treating water due to their high efficiency at lower dosages, and wider pH and temperature application ranges ( Sahu & Chaudhari 2013 ).
