Methods of reducing lost circulation in a wellbore using Saudi Arabian volcanic ash
A method of reducing lost circulation in a wellbore includes introducing an activation solution including an aqueous solution, Na2SiO3, NaOH, and one or both of CaCO3 or Mn3O4 into the wellbore. The method further includes introducing Saudi Arabian volcanic ash into the wellbore. The Saudi Arabian volcanic ash comprises SO3, CaO, SiO2, Al2O3, Fe2O3, MgO, and K2O. The method further includes allowing the Saudi Arabian volcanic ash to contact the activation solution in the wellbore, thereby forming a geopolymer barrier between the wellbore and a subsurface formation to reduce lost circulation in the wellbore.
