The present invention relates to aqueous compositions for forming a foam, comprising a surfactant and a particulate inorganic material, and optionally one or more polymers, such as soil conditioning polymers, and/or viscosity increasing polymers. The present invention further relates to the use and application of said aqueous compositions.

A method includes treating a reservoir with a damaged near wellbore region (NWR), including introducing a liquid foam treatment into a wellbore proximate to the damaged NWR, where the liquid foam treatment has a solution medium and nanobubbles, transmitting an acoustic wave towards the damaged NWR such that the nanobubbles collapse, causing fluid flow pathways to form for hydrocarbon production.

A system includes a solution generation tool for generating a liquid foam treatment, where the liquid foam treatment has a solution medium and nanobubbles, where the nanobubbles migrate along a concentration gradient, and an acoustic signal generator transmits an acoustic signal. The system also includes a downhole tool signally coupled to the acoustic signal generator fluidly coupled to the solution generation tool, and the downhole tool transmits an acoustic wave into an NWR and introduces the liquid foam treatment into the wellbore proximate to the NWR.

Compressed lost circulation materials for use in subterranean formations are provided. In some embodiments, the methods include: introducing a treatment fluid that includes a base fluid and a compressed lost circulation material into a wellbore penetrating at least a portion of a subterranean formation including a loss zone, the compressed lost circulation material including a binding material and a compressed material; allowing the binding material to at least partially degrade or dissolve; and allowing the compressed lost circulation material to at least partially expand in the subterranean formation.

Insulating fluids for use in drilling, production, and other applications are provided, the insulating fluids containing a porous medium (such as a sponge or foam) to limit the mobility of the liquid phase of the insulating fluid. The porous medium in the insulating fluid provides a mechanical means for reducing convective heat transfer, as the small pore spaces within the porous media create tortuous paths for the liquid moving therethrough. Methods include introducing the insulating fluid into an annulus of a drilling, riser, production, packer, or pipeline assembly to reduce heat transfer therethrough.
