摘要： The present invention provides the use of surface-modified nanoparticles in fluids used to recover hydrocarbon from underground formations. The use of surface-modified nanoparticles in such fluids provides foams that are stable under pressure yet have a shorter foam lifetime than typical surfactant-stabilized foams after the pressure is released or lowered.

摘要： A wellbore fluid including a peroxide degradable polymer and an encapsulated peroxide source. The peroxide degradable polymer may be a polysaccharide. The peroxide source may include an inorganic peroxide, including zinc and alkaline earth metal peroxides, such as magnesium peroxide. The encapsulating material may be a polymer, including enteric polymers. The release of peroxide, from peroxide source generally, can be controlled by means of pH such that peroxide source can be activated, and peroxide released, by a change in pH. In a wellbore, this pH change can be effected by using produced fluids to lower the pH of a more basic wellbore fluid.

摘要： The present invention relates to well bore operations, and more particularly, to contained micro-particles, and methods for using such contained microparticles in cementing operations. An exemplary method of facilitating the use of microparticles in a well bore fluid comprises the steps of providing contained micro-particles, and adding the contained micro-particles to the well bore fluid. In an exemplary embodiment, the well bore fluids of the present invention comprise encapsulated micro-particles. In another exemplary embodiment, the well bore fluids of the present invention comprise pelletized micro-particles.

摘要： Disclosed is a method for introducing additives into an oil, gas, or water injection well or pipeline in solid form at a location other than at the bottom. The method is practiced using pellets having a density sufficient to suspend the pellet at a top phase, bottom phase or at the interface of two phases of fluid within a wellbore. The pellets are prepared from a pellet matrix, such as an ethoxylated wax, and a weighting agent as well as an additive. By varying the amount of weighting agent, the density of the pellet can be varied to suspend it at a desired point to for a time sufficient to deliver the additive to the desired point within the wellbore.
