Fluid loss control agent. Cementing HTHP Fluid Loss Control-DOOL30; drag reducer for fracturing fluid; Polyacrylamide used as Oil Well Water-Plugging Agent; Gilsonite is similar to hard petroleum asphalt and is often called natural asphalt, it is soluble in aromatic solvents, as well as petroleum asphalt, due to its unique compatibility
Drag reduction behavior of hydrolyzed polyacrylamide
Partially hydrolyzed polyacrylamide (HPAM) as the main component of slickwater fracturing fluid is a shear-sensitive polymer, which suffers from mechanical degradation at turbulent flow rates. Five different concentrations of HPAM as well as mixtures of polyacrylamide/xanthan gum were prepared to investigate the possibility of improving shear stability of HPAM. Drag reduction (DR) measurements
The influence of polyacrylamide (PAM) as drag reducing polymer on flow of Iraqi crude oil in pipe lines was investigated in the present work. The effect additive concentration, pipe diameter, solution flow rate and the presence of radius elbows on the percentage of drag reduction (%Dr) and the amount of flow increases (%FI) were the variables of study.
Performance of polyacrylamide as drag reduction
The influence of polyacrylamide (PAM) as drag reducing polymer on flow of Iraqi crude oil in pipe lines was investigated in the present work. The effect additive concentration, pipe diameter
Drag reduction in pipe flow up to high shear rates of 30,000 sec-1 has been studied in tap water and in the synthetic brine. The velocity exponent has been observed to be 1.85 0.05 in these solvents and it decreased to values down to 1.4 with increased molecular weight of the additive.

Water Treatment Chemicals,Anionic PAM: It is widely used in waste water treatment of chemical
Adding polymer to a liquid was thought to reduce drag only up to a point, but new experiments have found exceptions to the usual limit. Frictional drag steals energy from a moving fluid, but the loss usually becomes greater as the flow goes from smooth, or “laminar,” to turbulent.
Understanding the Mechanism of Breaking Polyacrylamide

In a high Reynolds number fluid flow, significant energy loss occurs due to friction. However, by the addition of a minute amount of additives into this turbulent flow, frictional drag can be drastically reduced. This drag reduction phenomenon provides considerable motivation for diverse research to investigate its origin and application.
Covid-19 coronavirus: a cross-jurisdictional update
The Covid-19 pandemic coronavirus currently spreading across Europe, Asia-Pacific and the United States has resulted in an unprecedented demand for urgent tax relief measures across industries and sectors. Whilst the situation globally remains fluid central governments are coordinating action plans to limit the negative impact of Covid-19 and protect economies.
