Systems and methods for hydrofluoric (HF) acidizing compositions compatible with sensitive metallurgic grades. The systems and methods may include preparing an aqueous acidizing composition comprising one or more acid components, hydrofluoric acid, and one or more corrosion inhibitors; and injecting the aqueous composition into a subterranean formation containing sensitive metallurgic components via a wellbore.

Methods of treating a subterranean formation penetrated by a well bore, by diverting treatment fluid stages from zones of higher permeability to zones of lower permeability with an acid precursor material and fibers. The acid precursor material has an average particle size less than 1000 microns.

A mining machine applicable to fluidized mining and a mining method therefor are provided herein. A microwave transmitting mechanism, a liquid jet drill rod and a cutter-head are arranged at the head of a first excavation device of the mining machine. The ore body in front is first processed by the microwave transmitting mechanism and the liquid jet drill rod to reduce the strength of the ore body, which facilitates subsequent mining of the ore body, lowers the hardness requirements of the cutter-head, and reduces the wearing of the cutter-head. With this mining machine mining the ore body, the mined ores can be directly converted, under the ground, into resources in the easily transportable form, without transporting the ore to the surface for conversion, which saves the cost of transporting the ore to the surface.

A wellbore isolation device comprising: a material that dissolves via corrosion when in contact with a wellbore fluid, a surface of the material, wherein the surface of the material is altered via a surface treatment, and wherein the altered surface delays corrosion of the material for a desired amount of time. A method of removing the wellbore isolation device comprising: contacting or allowing the wellbore isolation device to come in contact with a wellbore fluid; and causing or allowing at least the portion of the material to dissolve.

A method for the fracking or stimulation of a hydrocarbon-bearing formation, said method comprising the steps of: providing a wellbore in need of stimulation; inserting a plug in the wellbore at a predetermined location; inserting a perforating tool and a spearhead or breakdown acid into the wellbore; positioning the tool at said predetermined location; perforating the wellbore with the tool thereby creating a perforated area; allowing the spearhead acid to come into contact with the perforated area for a predetermined period of time sufficient to prepare the formation for fracking or stimulation; removing the tool from the wellbore; and initiating the fracking of the perforated area using a fracking fluid. Also disclosed is a corrosion inhibiting composition for use with the acid composition.

A method of solution mining a subterranean mineral ore deposit such as trona ore in which a borehole is drilled from a subterranean mechanically-worked mineral ore mining operation to connect a mineral ore bed to be solution mined, using subterranean drilling apparatus located proximate to the mechanically-worked mineral ore mining operation. The mineral ore bed is isolated from the mechanically-worked mineral ore mining operation by passage of the drilled borehole through an impermeable layer adjacent to the mineral ore bed to be solution mined. The mineral ore bed is then solution-mined using a mining solvent introduced into the mineral ore bed to solubilize the mineral and form a mining solution, and the resulting mining solution is withdrawn from the mineral ore bed.
