Patent number: 7244693Abstract: A method for the treatment of a hydrocarbon well comprising administering down the well polymeric particles impregnated with a well treatment chemical or precursor or generator thereof. The particles have a pore volume of at least 20%, and are prepared by a process which comprises preparing an aqueous dispersion of polymer particles containing from 0.05 to 10 times by volume, based on the polymer, of one or more specific first material(s) adding a partly water-soluble second material having a water-solubility of at least ten times that of first material(s) under conditions which prevent or hinder transport of first material(s) through the aqueous phase, whereby second material diffuses into the polymer particles swelled with first material(s) and increases the volume of said particles by from 20 to 1000 times, based on the polymer.Type: GrantFiled: November 19, 2001Date of Patent: July 17, 2007Assignee: Statoil ASAInventors: Hans Kristian Kotlar, Olav Martin Selle, Oddvar Arnfinn Aune, Lars Kilaas, Anne Dalager Dyrli

Publication number: 20040074646Abstract: Gelatin capsules containing oil field chemicals, preferably weighted with a heavy metal compound, are made more stable under certain conditions by the incorporation of a strong chelating agent. The microcapsules can provide an extended treatment period since many materials that would damage the microcapsules are controlled by the chelating agent.Type: ApplicationFiled: October 27, 2003Publication date: April 22, 2004Inventors: Hans Kristian Kotlar, Olav Martin Selle, Oddvar Arnfinn Aune, Lars Kilaas, Anne Dalager Dyrli

Patent number: 6160061Abstract: A process for preparing an aqueous emulsion with a narrow droplet size distribution of an oily material comprising one or more highly water insoluble substances, wherein the oily material is homogenized in a hydrophilic phase in which the oily material is more soluble than in water, but still so insoluble that an emulsion is formed by the homogenization, and the emulsion is subsequently diluted with a high proportion of water to form a stable emulsion of the oily material having the desired narrow size distribution. The stable emulsion may be mixed with an excess of a partly water soluble material which becomes absorbed by the droplets of the oily material. Said partly water soluble material may comprise a polymerizable monomer, and polymerization is subsequently effected to prepare a dispersion of polymer particles, and if desired, the polymer particles are recovered from said dispersion.Type: GrantFiled: March 4, 1999Date of Patent: December 12, 2000Assignee: Nyfotek A/SInventors: Arvid Berge, Kari-Anne Leth-Olsen, John Ugelstad deceased, Anne Dalager Dyrli, Steinar Pedersen
