Patent CA-2485492-A1 (CA)
Title: Apparatus and method for analyzing well fluid sag
Inventor: MURPHY ROBERT J JR
IPC: E21B49/00
Filed: 2003-05-21
Abstract: An apparatus and method are disclosed for measuring or analyzing dynamic and static sag caused by settling of weighting materials in drilling fluids or other solids bearing fluid. The apparatus comprises a tube and shear shaft assembly (30) that allows for a controlled rate of shear to be applied to a sample of the fluid for testing. During a test, the assembly is placed on a pivotal holder (1) at an angle. The assembly has pistons (9) at the pivot center of the assembly which accommodate expansion and contraction of the test fluid due to changes in temperature and pressure, thereby allowing the test fluid to be heated, cooled and pressurized to simulate subterranean wellbore conditions without changing the center of mass of the test fluid. When weight material settles down the inclined assembly, the center of mass of the assembly changes resulting in changing torque or moment about the pivotal holder. The resultant moment is measured by energizing external coils (42) arranged to provide a uniform magnetic field. The bulk average settling rate is determined using the measured coil current rate of change.

Title: Hyperbranched polymers
Inventor: SODERGARD ANDERS
IPC: C09J167/04
Filed: 2003-05-30
Abstract: The present invention is directed to a process for preparing a hyperbranched polymer having a weight-average molar mass of at least 30,000, comprising coupling a first prepolymer having at least three functional end groups with a second prepolymer having at least two functional end groups by a dehydration condensation reaction between the end groups in the prepolymers. According to the present invention the number of arms and/or molar mass of the functionalized prepolymers can accurately be adjusted, thus affecting the properties of the resulting hyperbranched polymer in a desired way. Thus the polymer can be equipped e. g. with hydrophobic and hydrophilic parts. Also, the number of functional end groups, that optionally can be used for further chemical reactions, in the hyperbranched polymer can easily be adjusted to a desired level. The hyperbranched high molar mass polymer can be prepared in high yields without the use of organic solvents or linking compounds, which is advantageous from an environmental as well as an economical point of view.

Abstract: La présente invention concerne des procédés et systèmes permettant de traiter un flux de déchets (202) dans un système de retraitement des déchets (204). On a recours à cet effet à un process distinct (206) par lequel on met le flux de déchets (202) en contact avec un gaz riche en gaz détonnant (214) produit sur site par un générateur ad hoc (207). Le fonctionnement de ce générateur (207) fait appel de préférence à l'utilisation d'un signal électrique pulsé appliqué à une série d'électrodes qui sont peu espacées les unes des autres et plongées dans le flux de déchets (202). Ce process permet de dissocier du courant de déchets (202) un composant aqueux, en dégageant en même temps un gaz riche en gaz détonnant (214, 220). Le fonctionnement du générateur de gaz (207) dans le courant de déchets (202) peut donner lieu à un ou plusieurs process distincts (206) de traitement des déchets, et notamment le conditionnement, la stabilisation, l'épaississement et la déshydratation. Une partie au moins du gaz riche en gaz détonnant (220) peut être reprise pour une deuxième utilisation (222) dans le système de retraitement des déchets, et servir de source de combustible pour l'incinération ou la production d'énergie.
