Abstract: Particles that comprise calcium methylglycine diacetic acid salt (“Ca-MGDA salt”) may be useful for fluid diversion in subterranean operations. In some instances, the particles may be formed in the subterranean formation. For example, a method may involve introducing a treatment fluid into a wellbore penetrating a subterranean formation, wherein the treatment fluid comprises an aqueous base fluid, MGDA or salt thereof, and an acid in an amount of about 3% or greater by weight of the aqueous base fluid; acidizing a portion of the subterranean formation comprising calcium carbonate resulting in a concentration of calcium in the treatment fluid that exceeds about 50,000 ppm; and precipitating a plurality of particles that comprise a Ca-MGDA salt in the portion of the subterranean formation, thereby reducing fluid flow therethrough. In some instances, the particles that comprise Ca-MGDA salt may be included in a treatment fluid before introduction into the subterranean formation.

Abstract: A package is disclosed for housing a trap-sealed blister card within an outer housing with an optional window (142) for viewing a product (P) in the blister (300).

Abstract: A method for acidizing subterranean formations may include providing a treatment fluid comprising an aqueous carrier fluid, an acid, and a chelating agent comprising N-(phosphonomethyl)iminodiacetic acid, the treatment fluid having a pH at or below that at which carboxylic or phosphonic acid groups of the N-(phosphonomethyl)iminodiacetic acid are protonated and the chelating agent is ineffective for complexing a metal ion; introducing the treatment fluid into a wellbore penetrating a subterranean formation comprising a carbonate mineral; reacting the acid with the carbonate mineral in the presence of the chelating agent, such that the acid at least partially spends as the pH of the treatment fluid rises; and complexing a metal ion with the chelating agent once the pH of the treatment fluid rises above a pKa value for one or more of the carboxylic or phosphonic acid groups of the N-(phosphonomethyl)iminodiacetic acid.

Abstract: A package is disclosed comprising an outer blister portion and an inner blister portion, each blister portion having a flange, the flanges enclosed between paperboard cards, arranged so that upon rotation of the outer blister portion access is obtained to compartments within the inner blister portion. The compartments may hold product items.

Abstract: Security packages are disclosed having features that give increased resistance against theft by preventing or slowing opening of the package.

Abstract: A package is disclosed which includes hingedly connected front, back, and side panels, the package being held securely closed by a pair of sealing panels. The package is opened by a folding and pulling action.

Abstract: An inner sleeve having an interior chamber comprised of a bottom panel (12), a top panel (14), a pair of side panels (16,18) and a sealed front end formed by a pair of front closure panels (28, 30) and a pair of front closure flaps (32, 34). A locking flap (36) extends from the opposite end of the bottom panel and can be folded back over the bottom panel such that it will catch when inserted into an outer sleeve. An internal glue flap forms a barrier preventing contents inserted into the inner sleeve from inadvertently slipping out the rear end. A retaining flap (26) extends from the opposite end of the top panel and can be folded inward to create a one way gate that allows a blister pack to be inserted into the interior chamber without allowing it to be withdrawn.
