Abstract
The invention discloses a method of treating a subterranean formation of a well bore: providing a treatment fluid made of: a fluid; a particulate material, and a viscosifier material; wherein the viscosifier material is inactive in a first state and is able to increase viscosity of the treatment fluid when in a second state; introducing the treatment fluid into the wellbore; and providing a trigger able to activate the viscosifier material from first state to second state.
Claims51
A method of treating a subterranean formation of a well bore, comprising:
- a. providing a treatment fluid comprising a fluid, proppant, and a viscosifier material, wherein the viscosifier material is inactive in a first state and is able to increase viscosity of the treatment fluid when in a second state;
- b. introducing the treatment fluid into the wellbore;
- and,
- c. providing a trigger able to activate the viscosifier material from first state to second state.
A method of reducing the settling rate of a treatment fluid with proppant comprising:
- a. providing the treatment fluid comprising the proppant;
- b. providing a viscosifier material in the treatment fluid;
- c. providing a trigger able to activate the viscosifier material to increase viscosity of the treatment fluid such that the settling rate of the proppant in the treatment fluid is reduced.
A method of avoiding the settling rate of a treatment fluid with a particulate material and a degradable material comprising:
- a. providing the treatment fluid comprising the particulate material and the degradable material;
- b. providing a viscosifier material in the treatment fluid;
- c. providing a trigger able to activate the viscosifier material to increase viscosity of the treatment fluid when the degradable material dissolved in the treatment fluid, such that the settling rate of the particulate material in the treatment fluid is unchanged.
