Patent number: 8848485Abstract: Methods and apparatus for performing sonic well logging within a wellbore based on optical Distributed Acoustic Sensing (DAS) are provided. A sonic well logging system based on DAS may be capable of producing the functional equivalent of tens, hundreds, or even thousands of acoustic sensors. In this manner, the emplacement of the sonic well logging system based on DAS may not be nearly as complex or expensive as emplacing a sonic well logging system based on traditional methods. Furthermore, multiplexing may be simpler, downhole electronics need not be used, and the sonic well logging system may be used in extreme, high temperature environments.Type: GrantFiled: May 12, 2011Date of Patent: September 30, 2014Assignee: Weatherford/Lamb, Inc.Inventor: Francis X.

Patent number: 8496053Abstract: A method and apparatus for preventing erosion of a cable for use in a wellbore is described herein. The cable has one or more optical fibers adapted to monitor and/or control a condition in the wellbore. The cable includes a layer of elastomeric material at least partially located on an outer surface of the cable. The elastomeric material is adapted to absorb energy due to the impact of particles in production fluid or wellbore fluid against the cable.Type: GrantFiled: March 1, 2007Date of Patent: July 30, 2013Assignee: Weatherford/Lamb, Inc.Inventors: Jeffrey J.

Publication number: 20120092960Abstract: Methods and systems are provided for performing acoustic sensing by utilizing distributed acoustic sensing (DAS) along a length of a conduit, such that the sensing is performed with the functional equivalent of tens, hundreds, or thousands of sensors. Utilizing DAS in this manner may cut down the time in performing acoustic sensing, which, therefore, may make acoustic sensing more practical and cost effective and may enable applications that were previously cost prohibitive with discrete acoustic sensors.Type: ApplicationFiled: October 19, 2011Publication date: April 19, 2012Inventors: GRAHAM GASTON, Francis X.

Patent number: 7475732Abstract: The present generally relates to apparatus and methods for instrumentation associated with a downhole deployment valve or a separate instrumentation sub. In one aspect, a DDV in a casing string is closed in order to isolate an upper section of a wellbore from a lower section. Thereafter, a pressure differential above and below the closed valve is measured by downhole instrumentation to facilitate the opening of the valve. In another aspect, the instrumentation in the DDV includes sensors placed above and below a flapper portion of the valve. The pressure differential is communicated to the surface of the well for use in determining what amount of pressurization is needed in the upper portion to safely and effectively open the valve. Additionally, instrumentation associated with the DDV can include pressure, temperature, seismic, acoustic, and proximity sensors to facilitate the use of not only the DDV but also telemetry tools.Type: GrantFiled: May 3, 2007Date of Patent: January 13, 2009Assignee: Weatherford/Lamb, Inc.Inventors: David G.
