Patent number: 8947974Abstract: A downhole tool starts recording seismic energy. During the recording time, a surface seismic source is activated a specified number of times with a nominally defined separation between successive. The downhole sensor receives seismic waves resulting from the activation, but the time of the shooting sequence is not known downhole. The recorded data stream is processed and converted in real-time into seismic traces. A predefined number of traces are stacked and the quality of this sliding stack is used to detect time of the shooting sequence. The method could be used to detect one or several shooting sequences during a measurement window.Type: GrantFiled: June 15, 2010Date of Patent: February 3, 2015Assignee: Baker Hughes IncorporatedInventors: Radu Coman, Michael Neubert, Holger Mathiszik, Michael Koppe

Patent number: 8055448Abstract: A downhole acoustic logging tool is used for generating a guided borehole wave that propagates into the formation as a body wave, reflects from an interface and is converted back into a guided borehole wave. Guided borehole waves resulting from reflection of the body wave are used to image a reflector.Type: GrantFiled: June 13, 2008Date of Patent: November 8, 2011Assignee: Baker Hughes IncorporatedInventors: Holger Mathiszik, Tim W.

Patent number: 7954560Abstract: A wellbore drilling system utilizes optical fibers to measure parameters of interest and to communicate data. One or more electrical conductors are used to provide power to the components of the drilling system. The acquisition electronics for operating fiber optic sensors can be positioned at the surface and/or in the wellbore. In some embodiments, one optical fiber includes a plurality of sensors, each of which can measure the same or different parameters. A multiplexer multiplexes optical signals to operate such sensor configurations. Optical fiber sensors for acoustic measurements can include a cylindrical member wrapped by one or more optical fibers. The sensors can be configured as needed to provide a 3D representation of the pressure measurements.Type: GrantFiled: September 13, 2007Date of Patent: June 7, 2011Assignee: Baker Hughes IncorporatedInventors: Holger Mathiszik, Sebastian Csutak, Volker Krueger

Patent number: 7770663Abstract: Measurements are made continuously with a seismic while drilling (SWD) system and the measured data are stored in a working memory of a downhole processor along with quality control (QC) measurements. The QC data are analyzed and based on the analysis, portions of the data in working memory are recorded in permanent memory for retrieval. Alternatively, QC measurements are made substantially continuously predictions are made when data quality for SWD measurements are likely to be good. Recording of SWD data are then started based on the prediction.Type: GrantFiled: November 27, 2007Date of Patent: August 10, 2010Assignee: Baker Hughes IncorporatedInventor: Holger Mathiszik

Patent number: 7730967Abstract: A drilling system includes a control unit and a bottomhole assembly (BHA) coupled to a drill string. The control unit uses measurements from sensors distributed throughout the drill string and BHA to determine the physical condition of the drill string and BHA and to determine whether drilling can be optimized. The drill string sensors are housed in receiver subs and optionally can be positioned on extensible members. The receiver sub also can include a short-hop telemetry module, a processor module, and a clock module. In one embodiment, the receiver subs include seismic sensors for enabling vertical seismic profiling. During operation, the processor visually presents to the operator via one or more graphical user interfaces a dynamically updated pictorial image representing the drilling system. The image is annotated with an appropriate visual signal to indicate a determined physical condition at a given location or component.Type: GrantFiled: June 22, 2004Date of Patent: June 8, 2010Assignee: Baker Hughes IncorporatedInventors: Ray Ballantyne, Holger Mathiszik, Michael Neubert

Patent number: 7633834Abstract: A procedure to determine VSP-WD (Vertical Seismic Profiling—While Drilling) first breaks in absolute time is described. By combining a seismic surface source and firing complex seismic pattern unique in time (with a highly accurate surface—downhole time reference system), an automatic downhole procedure for first break detection on the downhole data, even under harsh conditions (low signal to noise ratio), is established. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).Type: GrantFiled: November 8, 2007Date of Patent: December 15, 2009Assignee: Baker Hughes IncorporatedInventors: Holger Mathiszik, Graham A.

Publication number: 20090205899Abstract: Acoustic measurements made in a borehole using a multipole source are used for imaging a near-borehole geological formation structure and determination of its orientation. The signal to noise ratio (as defined by the ratio of the signal radiated into the formation to the axially propagating signal) depends upon the type of source (force or volume) and its position in the borehole (on the tool, in the fluid or on the borehole wall).Type: ApplicationFiled: February 18, 2009Publication date: August 20, 2009Applicant: Baker Hughes IncorporatedInventors: Tim W.
