Certain foamed gel treatment fluids and methods of using the treatment fluids in wellbores penetrating subterranean formations are provided. In one embodiment, the treatment fluids comprise: an aqueous base fluid, a gas, a plurality of particulates, and a plurality of swellable particles each comprising a material having a first monomer, a second monomer, and a third monomer comprising a foamable surfactant. In one embodiment, the methods comprise: preparing a treatment fluid comprising an aqueous base fluid and a swellable particle that comprises a material having a first monomer, a second monomer, and a third monomer comprising a foamable surfactant; introducing the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation; and blending the treatment fluid while in the wellbore to form a foamed gel.

The present specification refers to a patent of invention for a foam formulation and its use in the temporary plugging of pipes, where the foam has volumetric and time stability, is prepared from a solution containing surfactant, co-surfactant, alkaline substance and LDH nanoparticles, is able to have its viscosity increased over time and remain intact for 8 hours or more even under pressure differences of up to 0.1 bar and a temperature of 60° C. and then it is able to disperse simply by using water or even the fluid transported in the pipeline. The LDH nanoparticle reinforced foam of the present invention can be applied in pipes that need to be plugged when they are undergoing maintenance, either to prevent incandescent soldering splashes from coming into contact with an explosive atmosphere or to avoid contamination in the pipe interior, among other applications. The present invention belongs to (but is not limited to) the field of plugs for pipes with explosive atmospheres and can be applied in systems that require temporary plugs that can be easily remover by using water or another solvent.

A method of treating a lost circulation zone may include positioning a cured lost circulation material composition in the lost circulation zone of a subterranean natural resource well to produce a barrier operable to mitigate wellbore fluids from passing into the lost circulation zone. The cured lost circulation material composition may be a foam comprising a gas phase and a liquid phase. The cured lost circulation material composition may include a cured bisphenol epoxy resin, one or more surfactants positioned at the interface of the liquid phase and the gas phase of the foam and carbon dioxide in the gas phase of the foam. The cured bisphenol epoxy resin may be a reaction product of a bisphenol epoxy resin system including uncured bisphenol epoxy resin, one or more curing agents, and optionally, a diluent. The carbon dioxide may be a reaction product of one or more carbon dioxide gas-generating compounds.

Various embodiments disclosed relate to compositions including mycelium and methods of treatment of subterranean formations with the same. In various embodiments, the present invention provides a method of treating a subterranean formation including placing in the subterranean formation a composition including a mycelium.

A subterranean system including a tunnel network, a plurality of syntactic foam panels, and a wireless communications network is disclosed. The wireless communications network comprises a plurality of wireless transceivers positioned throughout the tunnel network. The wireless communication range defined by communicatively coupled transceivers is a function of signal strength attenuation in a wireless signal traveling between the communicatively coupled transceivers. The tunnel network comprises tunnel support structure that contributes to the signal strength attenuation and a plurality of support apertures formed in the tunnel support structure. The syntactic foam panels are secured to the tunnel support structure to cover at least some of the support apertures and the composition and configuration of the syntactic foam panels are such that the panels do not make a significant contribution to the signal strength attenuation between communicatively coupled transceivers.
