A method to reduce the deposition of solid sulfur (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) present in the gas resulting in the reduction of the deposition of solid sulfur (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.

Using silica nanoparticles to reduce the deposition of solid sulfur in natural gas wells

A method to reduce the deposition of solid sulfur (Ss(s)) in a natural gas producing well, is described wherein the inside of the pipes used in the well are coated with a coating comprising polar surface treated nanoparticles. The polar surface treated nanoparticles interact with the sulfur gas and interfere with the deposition of solid sulfur onto the surface of the pipe. The polar surface treated nanoparticles are selected from the group consisting of silica, alumina and silica-aluminate, metal sulfates and metal oxides.

Provided herein are methods of increasing production from a hydrocarbon containing formation by adding a proppant to the formation, wherein a treatment fluid comprising a colloidal silica nanoparticle is added to the formation before, during or after the time the proppant is added to the formation.

Enhanced oil recovery using treatment fluids comprising colloidal silica with a proppant

This invention describes and claims the stimulation of several Wolfcamp and Bone Springs targeted wells in the northern Delaware Basin using fracturing treatments and a new method employing relatively small pre-pad pill volumes of Brine Resistant Silicon Dioxide Nanoparticle Dispersions ahead of each stage of treatment have been successfully performed. The invention includes a method of extending an oil and gas system ESRV comprising the steps of adding a Brine Resistant Silicon Dioxide Nanoparticle Dispersion ('BRINE RESISTANT SDND') to conventional oil well treatment fluids. The invention also includes a method of increasing initial production rates of an oil well by over 20.0% as compared to wells either not treated with the BRINE RESISTANT SDND technology or treated by conventional nano-emulsion surfactants. The Method focuses on the steps of adding a Brine Resistant Silicon Dioxide Nanoparticle Dispersion to conventional oil well treatment fluids.
