摘要： Copolymers containing acryloylmorpholine and vinylimidazole, and optionally vinylcaprolactam and/or n-vinyl pyrrolidone, have shown superior results in hydrate inhibition tests at conditions of 7° C. subcooling dosed at 1 vol % based on the water cut of the system fluids. The copolymer product has also passed high TDS (total dissolved solids) brine compatibility tests and secondary property tests including foaming and hot injection tests which make it useful as a kinetic hydrate inhibitor in gas production systems susceptible to the formation of natural gas hydrates.

摘要： In a method for optimizing gas lift operations in the production of crude oil, a surfactant is injected into the an oil well such that the surface tension between a lift gas and the formation fluid being produced is reduced and/or a lift gas-formation fluid foam is formed. The reduction in surface tension and/or foam formation increases the efficiency of the lift gas for lifting the formation fluid to the surface. The surfactant is a silicone resin which may be combined with other surfactants, in some embodiments.

摘要： An oxygen scavenger composition is effective in reducing oxygen-induced corrosion in aqueous systems that contain water, oxygen and a significant proportion (at least about 20 wt %) of a glycol, such as monoethylene glycol (MEG). The oxygen scavenger composition contains a sulfite, a transition metal salt, and a stabilizer to enhance the kinetics of oxygen removal (scavenging). The oxygen scavenger composition is particularly suitable when the transition metal salt component includes at least two different transition metals together, such as Ni and Co, or Ni and Mn.

摘要： Multi-valent metals, such as iron, may be removed from crude oil by introducing at least one metal removal chemical to the crude oil before, during or after the crude oil is charged to a settling tank. After mixing the metal removal chemical with the crude oil, the crude oil is kept still or held quiescent for an effective period of time to allow the metal species to settle to the bottom of the tank. Oil having reduced metal content may be removed from the top of the tank and/or metal-rich oil may be drained from the bottom of the tank or both. The crude oil having reduced metal content will cause fewer problems downstream in the refinery.
