A method to reduce the deposition of solid sulfur (S.sub.8(s)) in a natural gas producing well is described where hydrophobic surface modified silica nanoparticles are added into the tubing string, and the hydrophobic surface modified silica nanoparticles interact with the gaseous sulfur (S.sub.8(g)) present in the gas resulting in the reduction of the deposition of solid sulfur (S.sub.8(s)), The hydrophobic surface modified silica nanoparticles are selected from the group that includes silica, alumina and silica-aluminate. The hydrophobic surface modified silica nanoparticles may be added to the tubing string either dry or mixed first into a carrier fluid, which carrier fluid may be a liquid or a gas.

An additive composition for a well fluid and method of use. The additive composition is formulated to remove contaminates, such as hydrogen sulfide, asphaltenes, and paraffins from well fluids and improve well yield during oil and gas recovery and production operations. The additive composition is also used to clean and lubricate oil production equipment associated with the oil and gas recovery and production operations. A drip system may be used to introduce the additive composition into an oil well, tank, or pipe. Alternatively, a processing tool may be used to inject and circulate the additive composition into a tank to precipitate solid waste, heavy metals, and oil out of the well fluid

Solvent mixtures for downhole elemental sulfur removal and formation stimulation, and methods for utilizing such solvent mixtures, are described herein. One method includes providing a solvent mixture that includes an elemental sulfur solvent fraction and an odorant fraction that includes a lactate ester solvent. The method also includes injecting the solvent mixture into a hydrocarbon well such that the elemental sulfur solvent fraction of the solvent mixture dissolves elemental sulfur deposited on well components, and contacting the solvent mixture with water such that the lactate ester solvent within the odorant fraction reacts with the water to generate lactic acid. The method further includes stimulating a formation through which the hydrocarbon well extends by flowing the solvent mixture including the lactic acid through the hydrocarbon well and into the formation.
