  • What are SNF drilling fluid polymer additives?
  • SNF drilling fluid polymer additives include: Polymers for the enhancement of viscosity in the presence of bentonite in water-based drilling fluids. Highly efficient cationic permanent clay stabilizers manufactured in an easy-to-use liquid form. Highly efficient cationic permanent clay stabilizers manufactured in an easy-to-use liquid form.
  • Can you drill cement with PHPA mud?
  • Do not drill cement with PHPA muds, unless the system will be replaced after drilling out, because PHPA muds are sensitive to high pH, especially in the presence of high calcium levels. If drilling cement with a PHPA system is unavoidable, pretreat the system with 0.251bmlbbl [0.7 kg/m3] sodium bicarbonate.
  • What is the best pH for stabilisation of emulsion?
  • he addition of an acid.For specific cases, acid addition to the emulsion during production or directly in the solution can be ade for stabilisation .The best pH for stability of solutions at 5g/l of emulsion is below 6, and most preferred 5.5. The pH must be measured in the water which wi
  • How has PHPA mud changed the drilling process?
  • In wells drilled with PHPA mud, the number of bits was reduced from seven to two, rotating hours were reduced from 128 to 58, drilling progress was increased from 254 to 499 ftlD [77 to 152 mId], and total days were reduced from 12 to 6.
