  • 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.
  • Does PHPA reduce mud viscosity?
  • The addition of 1.0 lbm/bbl [2.9 kg/m3] PHP A reduced the free water to the point that the mud viscosity was excessive. This same mud operating at 15.3lbm/gal [1830 kg/m3] exhibited a normal viscosity. In retrospect, PHPA should have been added in stages and allowed to circulate several times between each stage to avoid these excessive viscosities.
  • 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.
  • Why was a PHPA/saturated-salt mud used to drill the section?
  • A PHPA/saturated-salt mud was used to drill the section for the following reasons. Salt was used to help prevent excessive washouts across the salt section and to provide ionic stabilization of the shales. The salt concentration was maintained at saturation (86, 000 mg/L chlorides).
