Patent number: 9714562Abstract: A downhole communications module for connecting with a string of downhole logging tools includes an optical annunciator and a communications port deployed in corresponding apertures in a tool body. The aperture housing the annunciator is sealed by a port plug having an optically transparent window. The aperture housing the communications port is sealed by a removable plug. A controller is deployed in the tool body and includes a memory module in electronic communication with the communications port. The controller is further configured to control operation of the annunciator.Type: GrantFiled: January 22, 2016Date of Patent: July 25, 2017Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Jonathan Yeboah, Sebastine Ujereh, Emil Steve Macha, Laurent Villegas, Christopher S.

Patent number: 9347277Abstract: A wireline configurable well logging instrument is connected to a drill pipe carrier and movable from a retracted position to an extended position. The drill pipe carrier is positioned on a pipe string that may comprise a portion of wired pipes communicatively coupled at each joint. Communication between the drill pipe carrier and the well logging instrument includes the use of inductive couplers, wires and combinations thereof.Type: GrantFiled: March 22, 2010Date of Patent: May 24, 2016Assignee: Schlumberger Technology CorporationInventors: Reza Taherian, Harold Steven Bissonnette, Chris Del Campo, Laurent Villegas, Shardul Sarhad

Patent number: 9217325Abstract: Methods and systems for determining whether a tool has been deployed below a drill pipe are provided. A downhole tool can measure various characteristics, which then can be analyzed to determine the likelihood of a tool having been deployed below the drill pipe. For example, density and porosity measurements can be affected by the presence of casing or drill pipe, and thus such measurements can provide an indication of whether the tool has been deployed below the drill pipe.Type: GrantFiled: August 18, 2013Date of Patent: December 22, 2015Assignee: Schlumberger Technology CorporationInventors: Laurent Villegas, Christopher S. Del Campo, Christian Stoller

Patent number: 8708041Abstract: A wellbore instrument system includes a pipe string extending from earth's surface into a wellbore. At least a portion of the pipe string includes a signal communication channel having a cable, such as an electrical conductor or an optical fiber. At least one wireline configurable wellbore instrument is coupled to the pipe string and has at least one sensor therein for measuring a physical parameter. The at least one instrument is in signal communication with the signal communication channel in the pipe string. The system includes a controller functionally associated with the at least one instrument and configured to initiate operation of the at least one sensor upon detection of a command signal.Type: GrantFiled: August 20, 2009Date of Patent: April 29, 2014Assignee: Schlumberger Technology CorporationInventors: Laurent Villegas, Christopher S. Del Campo, Shyam B. Mehta, Reza Taherian, Jean-Marc Follini

Patent number: 7812609Abstract: Improved receiver antennas are disclosed for long offset tensor induction army logging tools. The disclosed antennas include a bobbin which accommodates a ferromagnetic core. The outer surface of the bobbin is wrapped around a binding so that winding is thicker or includes more turns towards a center of the bobbin and is thinner or includes less turns towards the outer ends of the bobbin. The result is that the primary winding with a curved or parabolic profile that enhances the effective magnetic permeability and magnetic moment of the antenna. A secondary winding may also be utilized for flux feedback compensation. The elimination of winding turns towards the ends of the magnetic coil result in reduced DC resistance and the reduction in parasitic capacitance of the antennas. The disclosed antennas may be used in x-y-z receiver arrays.Type: GrantFiled: December 20, 2007Date of Patent: October 12, 2010Assignee: Schlumberger Technology CorporationInventors: Ismael Martinez, Dean M. Homan, Laurent Villegas, Gary A. Hazen
