  • Does PHPA affect the viscosity of water based fluids?
  • Due to its high molecular weight, PHPA quickly viscosifies with increased concentrations. The use of PHPA in drilling fluid formulation will affect its viscosity. A rheological study on PHPA in water is sufficient to know the influence of PHPA on the viscosity of water-based fluids.
  • What is the technology of PHPA mud systems?
  • Although more is known from field applications about how practices, although more is known from field applications about how the products work and the systems behave, the technology of PHPA mud systems is still developing. Drilling of oil and gas wells always results in the incorporation of native clays into the mud system.
  • 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.
  • Does PHPA encapsulation mean there are no free surface sites?
  • It was concluded that the assumed encapsulation of the cuttings particles by the high levels of PHPA in the fluids does not in fact mean there is no free surface sites, but the charged tails of adsorbed polymers prevent access to such surfaces by similar anionic flocculants.
