Abstract: The invention provides a dust repellant and anti-reflective inorganic coating and the method for preparing the coating. The dust repellant and anti-reflective inorganic coating includes nano-porous silica (SiO2) network of about 5 nm to about 35 nm and is characterized by cracks. The method of preparing the dust repellant and anti-reflective inorganic coating on a substrate includes mixing of aqueous SiO2 solution with a solvent. The aqueous SiO2 solution with the solvent is stirred to form a solution. The solution is coated on the substrate to form a film on the surface of the substrate. Thereafter, the film is annealed by heating the film to a temperature of about 500° C. to about 700° C. within a period of about 2 minutes to about 2 hours. Finally, the film is allowed to cool down.

Abstract: A method for reducing condensate in a subsurface formation is disclosed. The method comprises introducing a first reactant and a second reactant into the subsurface formation. The first reactant and the second reactant produce an exothermic reaction that increases temperature and pressure in the subsurface formation to greater than a dew point of the condensate. Increasing the temperature and pressure in the subsurface formation to greater than the dew point of the condensate vaporizes, and thereby reduces, condensate in the subsurface formation.

Abstract: A polymer gel composition for treating an aqueous zone of a subterranean formation may include a base polymer, a cross-linking agent, and an adsorption system. The adsorption system may include one or more silane compounds or a combination of silane compounds and silicates. The adsorption system may improve bonding of the polymer gel composition to the pore surfaces of the rock in the aqueous zone. A method of treating an aqueous zone of a subterranean formation may include injecting the polymer gel composition into the aqueous zone of the formation and allowing the polymer gel composition to cure to form a cross-linked polymer gel matrix that provides a barrier that reduces or prevents the flow of aqueous materials from the aqueous zone to the wellbore.

Abstract: A system and a method for applying 13C or 1H NMR spectroscopy to a sample of oil in order to calculate and assign an indicative property such as cetane number, pour point, cloud point, aniline point and/or octane number of a gas oil or naphtha fraction of the crude oil.

Abstract: The maxillary frenum clamping tool includes two articulating members, each of the members having a clamping end and a gripping end. The clamping ends of the articulating members are curved to retract the upper lip while clamping the maxillary labial frenum and have blunt tips to minimize damage to the surrounding tissue. Immediately below the blunt tips, each member defines a jaw section having a serrated inner edge. The outer edges of the jaw sections define guide indentations for guiding a curved suture needle. The gripping end of each member defines a finger loop and part of a ratcheting lock mechanism for locking the members at set positions. During use, the clamping too may be used to clamp the maxillary frenum with the jaw portions so that the clamped tissue can be easily sutured using the guide indentations.

Abstract: The composition for enhanced oil recovery includes metal oxide or carbonate nanoparticles capped or encapsulated by a water soluble poly(ionic liquid) (PIL). The nanoparticles may be, e.g., CaCO3, TiO2, Cu2O.Fe3O4, or ZrO2. The poly(ionic liquid) may be a copolymer of 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) with N-isopropyl acrylamide, N-vinyl pyrrolidone, methacrylic acid, or acrylamide. The composition is made by synthesizing the metal oxide or carbonate nanoparticles in the presence of the PIL. The resulting nanocomposite or nanomaterial alters the wettability of carbonate rock in a carbonate reservoir, releasing asphaltenic crude oil from the surface of the carbonate rock and replacing oil in the pores of the rock, thereby enhancing secondary and tertiary oil recovery.

Abstract: A hydrocarbon feedstock is hydrocracked in a hydrocracking zone and the effluent is fractioned to recover a light fraction, a middle fraction containing aromatic compounds and a heavy fraction. The heavy fraction is recycled to the hydrocracking zone for further hydrocracking. The middle fraction is introduced to an aromatic separation zone. A product stream is recovered from the aromatic separation zone comprising a middle fraction having a reduced content of aromatic compounds as compared to the middle fraction recovered from the fractionator. Aromatics from the aromatic separation zone are recycled to the hydrocracking zone for further hydrogenation and cracking.

Brine is added to the oil-emulsifier mixture to form the acid emulsion. Preferably, the brine has a salt concentration of about 20 kppm, and is added such that the volume ratio of the brine to the oil is about 70 to 30.
