  • Can KCl be used as a shale inhibitor in PHPA mud?
  • KCl is used as a shale inhibitor in most PHPA mud designs. In low-solids muds, PHPA interacts with minimal concentrations of bentonite to link particles together and improve rheology without increased colloidal solids loading.
  • Can PHPA be used in laboratory mud?
  • However, we have used 1lbm/bbl [2.9-kg/m3] PHPA concentration in NaCI and KCl muds in mud weights> 18 Ibm/gal [>2160 kg/m3] successfully. Interestingly, laboratory muds prepared with 1.01bmlbbl [2.9 kg/m3] PHPA at 18lbm/gal [2160 kg/m3] are much too viscous to pump.
  • Can PHPA be sheared with a polymer-shearing device?
  • The streams are directed to collide with each other under pressure. Both liquid and dry PHPA can be sheared with this device. Field results indicate that the use of a polymer-shearing device allows 0.5 to 1.0lbm/bbl [1.4 to 2.9 kg/m3] PHPA to be mixed at a high rate in one circulation.
