  • Mapping fracture dimensions
    Patent number: 7134492
    Abstract: Hydraulic fracture dimensions and, optionally, fracture closure pressure and time are determined by adding particulate matter that discharges to create an acoustic signal to the proppant, allowing the particulate matter to discharge, and detecting the acoustic signal with geophones or accelerometers. The particulate matter may be spheres or fibers. The discharge may be explosion, implosion, detonation, or rapid combustion or ignition. The discharge may be triggered by fracture closure or by chemical reaction.
    Type: Grant
    Filed: April 14, 2004
    Date of Patent: November 14, 2006
    Assignee: Schlumberger Technology Corporation
    Inventors: Dean Willberg, Jean Desroches, Kamal Babour, Kais Gzara, Christian Besson
  • Use of glycol ethers as biodispersants in heating and cooling systems
    Publication number: 20060251692
    Abstract: Disclosed is a method for controlling the formation of biofilms in cooling water systems or closed systems wherein water is cooled, heated and recirculated, by injecting a glycol ether or mixture of glycol ethers as biodispersant in the water of such systems. The glycol ethers are chosen to be soluble in water. The preferred glycol ethers result from the reaction between one or more alcohols with one or more epoxides, preferably chosen from ethylene oxide and propylene oxide.

  • Method and Apparatus to Isolate Fluids During Gravel Pack Operations
    Publication number: 20050252657
    Abstract: The present invention provides for an apparatus and method to displace fluids and to prevent the mixing or bypassing of fluids used in gravel pack operations. A moveable plug is used to create a physical partition between fluids.
