20130120093Downhole Inductive Coupler Assemblies - An inductive coupler assembly for use in a downhole environment and related methods are described. An example indicative coupler assembly includes a first inductive coupler having first and second magnetically coupled coils and a second inductive coupler having third and fourth magnetically coupled coils. The first and third coils are coupled to a first pair of signal lines and the second and fourth coils are coupled to a second pair of signal lines. The first inductive coupler is to magnetically convey a differential communications signal between the first and second pairs of signal lines, and the second inductive coupler is to magnetically convey a common mode power signal between the first and second pairs of signal lines.05-16-2013
20130181799Inductive Couplers for Use in A Downhole Environment - Inductive couplers for use in a downhole environment are described. An example inductive coupler for use in a downhole environment includes a body defining a cavity and magnetic material positioned in the cavity. The example inductive coupler also includes a coil adjacent the magnetic material, the coil formed with a number of turns of wire, and a first metal cover coupled to the body to enclose the cavity. The metal cover being electrically coupled to the body to form a substantially contiguous electrically conductive surface surrounding the cavity.07-18-2013
20140374085Apparatus and Methods for Testing Inductively Coupled Downhole Systems - Apparatus and methods for testing inductively coupled downhole systems are described. An example inductive coupler assembly for use in a wellbore includes an inductive coupler fixed to a completion in the wellbore, a drill pipe, a portion of which is to be located adjacent to the inductive coupler, and a sleeve surrounding the portion of the drill pipe to reduce a reluctance of a magnetic circuit including the inductive coupler.12-25-2014

20110100136METHOD OF DYNAMICALLY CORRECTING FLOW RATE MEASUREMENTS - A flow rate of a fluid flowing in a tubing is determined using a flow meter. The flow meter measures a value related to the flow rate. The tubing has a valve for controlling the fluid flowing through the flow meter. The method of determination of the flow rate includes closing the valve and measuring a first zero flow rate value at a first time and a second zero flow rate value at a second time, estimating an error of the value measurement based on the first and second zero flow rate values, opening the valve and measuring value of the flowing fluid, applying an error correction to the measured value of the flowing fluid, and calculating a corrected flow rate based on the corrected value of flowing fluid.05-05-2011
20110100642INSTRUMENTED TUBING AND METHOD FOR DETERMINING A CONTRIBUTION TO FLUID PRODUCTION - An instrumented tubing for determining a contribution of a given zone to fluid production of a reservoir, the instrumented tubing including a tube having an open end for collecting a fluid flowing from the given zone and a port for coupling the tube to a production tubing for letting the collected fluid flow into the production tubing, and a sensor for measuring a parameter of the collected fluid, wherein the sensor is connected to an electronic unit for determining the contribution of the given zone to the fluid production of the reservoir based on said measured parameter.05-05-2011
20120041681 Water Fraction Measuring Sensor and Method - A sensor for measuring water fraction in a fluid mixture flowing in a conductive tubing within a borehole. The sensor comprises: an active probe, a reference probe, and an electronic unit. The active probe includes a first electrode and a second electrode isolated from each other by a first insulating layer, the first and second electrodes are preferably in contact with the fluid mixture. The reference probe is formed from an internal wall of the conductive tubing contacting the fluid mixture and isolated from the reference probe by a second insulating layer. The electronic unit is coupled to the first and second electrodes, and to the reference probe, the electronic unit preferably includes a capacitance module for measuring a capacitance between the active probe and the reference probe.02-16-2012
