A variety of methods and compositions are disclosed, including, in one embodiment, a method of treating a well comprising: providing a treatment fluid comprising a base fluid and a blended cementitious component, wherein the blended cementitious component comprises kiln dust from two or more different sources; and introducing the treatment fluid into a well bore.
1. A method of cementing comprising: providing a settable composition comprising water and a blended cementitious component, wherein the blended cementitious component comprises kiln dust and an additional cementitious component, wherein the kiln dust is present in the treatment fluid in an amount i
1. A method of cementing comprising: providing a settable composition comprising water and a blended cementitious component, wherein the blended cementitious component comprises kiln dust and an additional cementitious component, wherein the kiln dust is present in the treatment fluid in an amount in a range of from about 0.01% to 99% by weight of the blended cementitious component;deteimining a reactive index of the kiln dust and the additional cementitious component; introducing the settable composition into a well bore; andallowing the settable composition to set to form a hardened mass. 2. The method of claim 1 wherein settable composition is used in primary cementing in the well bore. 3. The method of claim 1 wherein the base fluid comprises water selected from the group consisting of freshwater, saltwater, brine, and any combination thereof, and wherein the kiln dust is selected from the group consisting of lime kiln dust, cement kiln dust, and a combination thereof. 4. The method of claim 1 wherein the kiln dust comprises cement kiln dust. 5. The method of claim 1 wherein the amount of the kiln dust and the additional cementitious component is adjusted based on a parameter selected from the group consisting of compressive strength, Young's modulus, fluid loss, thickening time, a rheological value, free water, and any combination thereof. 6. The method of claim 1 wherein the step of determining the reactive index uses the following equation: RI1=MP1/SSA1 wherein RI1 is the reactive index for the kiln dust, MP1 is a measured parameter of the kiln dust, and SSA1 is the specific surface area of the kiln dust. 7. The method of claim 6 wherein the measured parameter is compressive strength, Young's modulus, fluid loss, thickening time, a rheological value, free water, or any combination thereof. 8. The method of claim 6 wherein performance of the blended cementitious component is optimized using the following equation: EPblend=(RI1)(SSA1)(f1)m+(RI2)(SSA2)(f2)m wherein EP is an estimated parameter for the blended cementitious component, f1 is mass fraction of the kiln dust, f2 is mass fraction of the additional cementitious component, and m is a number from 1 to 10, and wherein the optimizing comprises adjusting f1 and/or f2.
