Compositions and methods for removing scales within a subterranean environment are provided. The method includes placing a treatment fluid into the subterranean environment containing oil-laden scales and dissolving the oil-laden scales by contacting the treatment fluid to the oil-laden scales. The treatment fluid contains a solvent mixture containing a pyrrolidone and a terpene, an emulsifier, and a chelate mixture containing hydrochloric acid and a chelating agent that contains methylglycine diacetate.

Downhole fluid for removing scales and methods thereof

The present disclosure relates to acidizing treatment fluids for use in subterranean formation, such as wellbore, operations for dissolving iron sulfide scale, such as iron sulfide scale in sour conditions. Such treatment fluids comprise an aqueous base fluid; an acid; a chelating agent of methylglycine diacetic acid trisodium salt; and a hydrogen sulfide scavenger blend comprising 3-hydroxybutanal, crotonaldehyde, acetaldehyde, and a solvent base fluid.

Acidizing treatment fluids for use in subterranean formation operations

A composition and method for treating a subterranean formation that includes preparing a treatment gel of aqueous fluid, a thickening agent soluble in the aqueous fluid, sand/gravel, and micro fibrous cellulose. Placing the treatment gel in at least a portion of a subterranean formation.

High temperature gravel packing fluid system

Methods for stabilizing a formation containing water sensitive materials include forming a composition including at least one amido-amine based cationic gemini surfactant and treating the water sensitive materials with an effective amount of the composition.
