  • Monitoring wireline coupling and distribution
    Patent number: 10316641
    Abstract: Apparatus and methods for acquiring strain profiles of an optical conductor of a wireline cable in a wellbore, either while the cable is lowered and/or at intervals during the lowering when the cable is briefly stationary. Changes in the acquired strain profiles are utilized to infer or otherwise determine changes in the disposition of the cable.
    Type: Grant
    Filed: March 20, 2017
    Date of Patent: June 11, 2019
    Assignee: SCHLUMBERGER TECHNOLOGY CORPORATION

  • Microhydraulic fracturing with downhole acoustic measurement
    Patent number: 9477002
    Abstract: Methods and related systems are described for measuring acoustic signals in a borehole during a fracturing operation. The system includes a downhole toolstring designed and adapted for deployment in a borehole formed within a subterranean rock formation. A downhole rock fracturing tool opens and propagates a fracture in the subterranean rock formation. Dipole and/or quadrupole acoustic sources transmit acoustic energy into the subterranean rock formation. A receiver array measures acoustic energy traveling through the subterranean rock formation before, during and after the fracture induction. Geophones mounted on extendable arms can be used to measure shear wave acoustic energy travelling in the rock formation. The toolstring can be constructed such that the sources and receivers straddle the fracture zone during the fracturing.
