摘要： The present systems and methods utilize a polyamic acid solution as a precursor to form a polyimide bead having desired properties. The polyamic acid solution may be formed into a polyamic acid droplet. The polyamic acid droplet is then processed to form a polyamic acid bead, such as by extraction of solvent to concentrate the polyamic acid or by partial chemical imidization of the polyamic acid. The polyamic acid bead is then better able to retain its shape during subsequent processing steps, such as drying and pressurizing, before final thermal imidization.

摘要： A method and system for drilling a wellbore is described. The system includes a wellbore with a variable density drilling mud, drilling pipe, a bottom hole assembly disposed in the wellbore and a drilling mud processing unit in fluid communication with the wellbore. The variable density drilling mud has compressible particles and drilling fluid. The bottom hole assembly is coupled to the drilling pipe while the drilling mud processing unit is configured to separate the compressible particles from the variable density drilling mud. The compressible particles in this embodiment may include compressible hollow objects filled with pressurized gas an configured to maintain the mud weight between the fracture pressure gradient and the pore pressure gradient. In addition, the system and method may also manage the use of compressible particles having different characteristics, such as size, during the drilling operations.

摘要： The present invention relates to a latex comprising water and a layered material intercalated with a polymer. The invention also relates to a nanocomposite material comprising a layered material intercalated with a polymer. The latex can be produced by forming a dispersion of layered material in water, adding surfactant, polymerizable monomer or monomers, and a polymerization initiator to the mixture and then polymerizing the monomer to form a latex. The latex can also be formed from preformed polymers. Composite materials formed from latexes produced by either method have improved mechanical properties and reduced air permeability.

摘要： The synthesis, preparation and utilization of cationic viscoelastic monomer fluids mixed with cationic-alkyl containing copolymers are described. These fluid mixtures possess dramatic rheological behavior at very low concentrations as compared to the two individual components or even in comparison with most conventional water soluble polymers. Marked changes in solution properties are exhibited with minor modifications in the structure of the polymers, monomer structure, and monomer stoichometry.
