Abstract
Disclosed herein is a method of servicing a wellbore penetrating a subterranean formation, comprising: placing a cementitious composition of the type disclosed herein into the wellbore. The cementitious composition comprises a cement blend and water, wherein the cement blend comprises Portland cement and pozzolan, wherein the Portland cement is present in an amount of from equal to or greater than about 0.01 wt. % to equal to or less than about 25.0 wt. % based on the total weight of the cement blend.
Claims24
A method of servicing a wellbore penetrating a subterranean formation, comprising:
- placing a cementitious composition into the wellbore, wherein the cementitious composition comprises a cement blend and water,
- wherein the cement blend comprises Portland cement and pozzolan,
- wherein the Portland cement is present in an amount of from equal to or greater than about 0.01 wt. % to equal to or less than about 25.0 wt. % based on the total weight of the cement blend.
A method of servicing a wellbore penetrating a subterranean formation, comprising:
- placing a cementitious composition into the wellbore, wherein the cementitious composition comprises a cement blend and water,
- wherein the cement blend comprises Portland cement and pozzolan,
- wherein the Portland cement is present in an amount of from equal to or greater than about 0.01 wt. % to equal to or less than about 25.0 wt. % based on the total weight of the cement blend;
- and
- allowing at least a portion of the cementitious composition to set.
A method of reducing a carbon footprint of a wellbore servicing operation comprising:
- placing a cementitious composition comprising Portland cement and pozzolan into the wellbore, wherein the Portland cement is present in an amount of from equal to or greater than about 0.01 wt. % to equal to or less than about 25.0 wt. % based on the total weight of the cement blend and wherein the cementitious composition has a carbon footprint of equal to or less than about 150.0 kilograms of equivalent CO2 per barrel of the cementitious composition (kg/bbl).
