Abstract
Methods and compositions for treating subterranean formations to mitigate lost circulation are provided. The methods of the present disclosure include forming a treatment fluid including one or more geopolymer lost circulation materials; introducing the treatment fluid into at least a portion of a subterranean formation that includes at least one loss zone; activating the geopolymer lost circulation materials to form a geopolymer that imparts a thixotropic property to the treatment fluid; and allowing the treatment fluid exhibiting the thixotropic property to at least partially reduce a rate of loss associated with the loss zone.
Claims20
A composition comprising:
- a base fluid;
- and
- one or more geopolymer lost circulation materials, wherein the geopolymer lost circulation materials comprise:
- an aluminosilicate source,
- a metal silicate source;
- an activator;
- and
- water,
- wherein the composition has a crush strength of about 72 psi or less when measured after 7 days.
A composition comprising:
- a base fluid;
- and
- one or more geopolymer lost circulation materials, wherein the geopolymer lost circulation materials comprise:
- an aluminosilicate source,
- a metal silicate source;
- an activator, wherein the activator is present in an amount of 1.4-2.9% activator based on a total amount of the aluminosilicate source;
- and
- water,
- wherein the composition has a thixotropic rate of from about 27.6 lbf/100 ft2/min to about 50 lbf/100 ft2/min.
