  • Does adding PHPA to water based mud affect shale dispersion?
  • According to the results obtained, it was observed that the addition of PHPA to the formulation of the water-based mud affects relatively on the shale dispersion, where the amount of dispersion cuttings has decreased depending on the PHPA concentration and on the presence of the reactive clay in the different cutting samples.
  • How does PHPA co-polymer affect cutting dispersion test?
  • Effect of PHPA co-polymer on the cutting dispersion test The actions of bit and the swelling of cuttings give dispersed fine solid particles which increase the mud weight, low gravity solids and plastic viscosity of drilling fluid.
  • Why does KCl/PHPA reduce shale dispersion?
  • The combination of KCl/PHPA gives the low shale dispersion amount; this is due to PHPA's encapsulation role and K + cation swelling inhibition mechanism. For example, the formulation (F) with 4 ppb PHPA and 3% KCl gives the lower mass loss of shale particles which are weakly dispersed in shale erosion test. Fig. 6.
