  • Who are the leading water treatment chemicals suppliers in Ahmedabad?
  • Chemfert Chemicals is leading Water Treatment chemicals Suppliers Ahmedabad, Gujarat, Polymer for pilling india, PHPA chemical exporter and Drilling Starch suppliers in Ahmedabad, Gujarat, India.
  • 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.
  • What polymers are used in drilling?
  • PAC, xanthan gum (XGD), carboxymethyl cellulose (CMC), starch, and partially-hydrolyzed polyacrylamide (PHPA) are the most commonplace polymers in drilling industry (Thomas 1982;Plank and Gossen 1991;Oswald et al. 2006;Balestrini et al. 2009; Kelessidis et al. 2013; Toka and Toka 2015;Villada et al. 2017).
  • 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).
