Abstract: Provided is an acid retarder composition, a well treatment fluid, and a method of treating a subterranean formation for slow-reacting acidizing operations. An acid retarder composition for acidizing a subterranean formation includes a nitrogen-containing derivative of carbonic acid, a quaternary ammonium compound, and a surfactant. Well treatment fluids include an aqueous medium, an acid, and an acid retarder composition including a nitrogen-containing derivative of carbonic acid, a quaternary ammonium compound, a surfactant. Methods of treating a subterranean formation include injecting a well treatment fluid including an aqueous medium, an acid, and an acid retarder composition including a nitrogen-containing derivative of carbonic acid, a quaternary ammonium compound, and a surfactant into a subterranean formation.

Abstract: A system is disclosed that obtains an image of an apparel item and text describing the apparel item. The system also determines descriptive metadata of the apparel item by extracting information from the text. Further, the system further determines categorization metadata of the apparel item by analyzing the image. Additionally, the system stores the image, the descriptive metadata, and the categorization metadata in a virtual closet. Moreover, the system provides a recommendation of an outfit from a stylist to a user based on the virtual closet.

Abstract: The flow of a fluid may be diverted from a high permeability zone to a low permeability portion of a subterranean formation by use of particulates comprising dicarboxylic acid, ester or an anhydride of the formula: or an anhydride thereof, wherein R1 is —COO—(R5O)y—R4 or —H; R2 and R3 are selected from the group consisting of —H and —COO—(R5O)y—R4, provided both R2 and R3 are —COO—(R5O)y—R4 when R1 is —H and further provided only one of R2 or R3 is —COO—(R5O)y—R4 when R1 is —COO—(R5O)y—R4, R4 is —H or a C1-C6 alkyl group, R5 is a C1-C6 alkylene group, and each y is 0 to 5. The dicarboxylic acid, ester or anhydride may further be admixed with an aliphatic polyester having the general formula of repeating units: where n is an integer between 75 and 10,000 and R is selected from the group consisting of hydrogen, alkyl, aryl, alkylaryl, acetyl, heteroatoms, and mixtures; thereof.

Abstract: A fluid-impermeable barrier, used to isolate stimulated intervals in a reservoir during a multi-zone fracturing operation, may be removed from the wellbore which penetrates the reservoir using a circulating fluid containing dissolvable solid particulates. The dissolvable solid particulates bridge perforation clusters during clean-out of the wellbore and thus inhibit passage of the circulating fluid into the fracture network through the perforation clusters.
