  • Patent number: 11619113
    Abstract: Exemplary embodiments seek to eliminate or reduce fouling enabled by atmospheric oxygen entering the airspace of the well column. An inerting gas is used to flush atmospheric oxygen out of the well airspace. Once atmospheric air in the well gas-column has been replaced with an inerting gas, the well is sealed and pressurized with the inerting gas. The introduction of atmospheric oxygen back into the system through leaks is overcome by keeping a small, positive pressure-differential between the well-column gas pressure and the atmosphere. Results, as described herein, have shown the removal of atmospheric oxygen from the system can greatly reduce, or eliminate, both chemical and biological fouling as well as reduce or eliminate the need for well cleaning treatments.

  • Patent number: 11203709
    Abstract: Disclosed herein are compositions and methods for increasing recovery, or flowback, of hydrocarbon compounds from hydrocarbon-containing subterranean fractured rock formations (tight shale reservoirs). The flowback compositions include an anionic dimer surfactant, an anionic monomer surfactant, and a demulsifier. The flowback compositions convert oil-wet rocks to water-wet, yet exhibit a low tendency of composition components to sorb to the rock. The flowback compositions do not cause formation of emulsions with hydrocarbon compounds within the subterranean fractured rock formations. The flowback composition are useful for increasing the yield of hydrocarbons recovered from tight shale reservoirs.

  • Patent number: 11162016
    Abstract: This invention is broadly concerned with compositions and processes for oilfield applications. More specifically, this invention relates to novel polymer constructed packages that, when pumped into a petroleum well, provide tunable characteristics of transformation and delayed self-assembly with each other under reservoir conditions to yield strong, elastic, bulk gel materials. The compositions comprise a polymer, assembling agents, and optional additives used for the re-assembly stage are uniformly-distributed within the initial gel particles. The polymer particle packages absorb water and swell upon exposure to water, thus exposing the “assembling agents” that enable re-assembly. Both swelling and re-assembly are proportionally controlled via compositions to be tunable to allow functional dispersion and subsequent self-assembly under various reservoir conditions.
