Multiple functional wellbore fluid additive
The embodiments described herein generally relate to methods and chemical compositions for use with wellbore treatment processes. In one embodiment, a composition is provided comprising a cementitious material, a drilling fluid, or combinations thereof, and an additive composition comprising one or more components selected from the group of an aqueous insoluble lignin, a coke fine, a random tetracopolymer having the formula styrene-butadiene-acrylic-fumaric acid, a polyvinyl acetate, a surfactant composition, and combinations thereof.
1. A composition, comprising:
a cementitious material, and
an additive composition comprising:
an aqueous insoluble lignin,
a random tetracopolymer comprising monomers of styrene, butadiene, acrylic acid, and fumaric acid,
a polyvinyl acetate, and
a surfactant composition comprising a nonionic surfactant disposed in a microporous carrier.
2. The composition of claim 1 , wherein the composition comprises:
from about 90 wt. % to about 99.9 wt. % of the cementitious material; and
from about 0.1 wt. % to about 10 wt. % of the additive composition.
3. The composition of claim 2 , wherein the additive composition comprises from about 0.1 to about 50 wt % of the aqueous insoluble lignin.
4. The composition of claim 1 , wherein the cementitious material comprises one or materials selected from the group consisting of cement, fly ash, clay, silica flour, and combinations thereof.
5. The composition of claim 1 , wherein the cementitious material further comprises water and is in the form of a slurry.
6. The composition of claim 5 , wherein the aqueous insoluble lignin comprises Kraft lignin.
7. The composition of claim 1 , wherein the additive composition comprises:
from about 0.1 to about 99.7 wt % of the aqueous insoluble lignin;
from about 0.1 to about 99.7 wt % of the random tetracopolymer;
from about 0.1 to about 99.7 wt % of the polyvinyl acetate; and
from about 0.1 to about 99.7 wt % of the surfactant composition, wherein the total wt. % is 100 wt. % of the additive composition.
8. The composition of claim 1 , wherein the aqueous insoluble lignin comprises Kraft lignin.
9. The composition of claim 1 , further comprising one or more additives selected from the group consisting of defoaming agent, dispersant, free water control agent, and combinations thereof.
10. The composition of claim 1 , wherein the surfactant composition further comprises an ionic surfactant.
