Abstract: A treatment fluid for treating a portion of a subterranean formation comprises: a base fluid, wherein the base fluid comprises a hydrocarbon liquid; and a gellant, wherein the gellant: is a polymer; and is activated at an activation temperature, wherein the thermal activation of the gellant causes the treatment fluid to become a gel. A method of treating a portion of a subterranean formation includes introducing the treatment fluid into the portion of the subterranean formation, wherein the subterranean formation is penetrated by a well, wherein at least a portion of the well has a bottomhole temperature greater than or equal to the activation temperature, and wherein the step of introducing comprises introducing the treatment fluid into the portion of the well.

Abstract: A treatment fluid comprises: a base fluid; and at least one additive, wherein the additive: (i) comprises a fluorinated compound; and (ii) is a lubricant that is surface active. The additive can reduce the coefficient of friction between two or more surfaces. The surfaces can be the surface of a wellbore component. The additive can also be a corrosion inhibitor. A method of treating a portion of a well comprises: forming the treatment fluid; and introducing the treatment fluid into the well.

Abstract: A method of converting an inactive biocide into an active biocide comprises: contacting the inactive biocide with an activating agent, wherein the activating agent is capable of chemically reacting with the inactive biocide; and causing or allowing a chemical reaction to take place between the inactive biocide and the activating agent, wherein the chemical reaction produces the active biocide. The methods can also include deactivating the active biocide via a chemical reaction between the active biocide and a deactivating agent.

Abstract: Fluids and associated methods useful in subterranean applications are provided. More particularly, methods of reducing drill string sticking are provided, which include: providing a spotting fluid composition comprising a water insoluble external phase fluid, a water soluble internal phase fluid, and an ether carboxylic acid emulsifying agent; introducing the spotting fluid to the vicinity of a desired portion of a drill string; and allowing the spotting fluid to interact with a portion of material surrounding the desired portion of the drill string spotting fluid. Compositions are provided that may be useful in subterranean applications for addressing, among other things, drill string sticking problems. Additional optional components may be used, such as viscosifiers, weighting agents, and wetting agents.

Abstract: A method for the removal of soluble metal ion contamination from fluids is disclosed. The method includes passing the contaminated fluid through a filter medium comprising a reducing metal and a filter aid, such as diatomaceous earth, and collecting a filtrate with lower concentration of soluble metal ion contamination. The reducing metal can have a reduction potential of from ?0.50 volt to ?3.10 volt and can be capable of reducing the soluble metal ions to insoluble metal, which can then be entrapped in the filter medium or otherwise separated.
