An apparatus usable with a well includes an explosive pellet that is adapted to be communicated into the well via a fluid and includes an explosive material that is adapted to be detonated downhole in the well. The apparatus further includes an encapsulant to encapsulate the explosive pellet to inhibit unintended detonation of the explosive material. The encapsulant is adapted to be at least partially removed from the explosive pellet in response to the explosive pellet being communicated into the well.

Encapsulated explosive pellet

A method of forming a wellbore fluid, the method including introducing a hydratable polymer and introducing a crosslinker comprised of at least a silica material, the crosslinker having a dimension of from about 5 nm to about 100 nm.

A method of treating a subterranean formation penetrated by a wellbore of a well having iron-containing components is carried out by introducing a treatment fluid into the wellbore of the well. The treatment fluid is formed from an aqueous solution, a mineral acid, a viscoelastic surfactant gelling agent and corrosion inhibitor system containing at least one of an alkyl, alkenyl, alicyclic or aromatic substituted aliphatic ketone and aliphatic or aromatic aldehyde. The treatment fluid is substantially free of any formic acid or precursor formic acid. In certain embodiments, the corrosion inhibitor system comprises a mixture of at least one of an alkenyl phenone or &#x3b1;,&#x3b2;-unsaturated aldehyde, an unsaturated ketone or unsaturated aldehyde other than the alkenyl phenone and &#x3b1;,&#x3b2;-unsaturated aldehyde, a dispersing agent, an extender and an alcohol solvent. A corrosion inhibitor intensifier may also be used in certain embodiments, which may include a mixture of cuprous iodide and cuprous chloride.
