Patent number: 7379180Abstract: A fluid analysis system for use downhole comprises an input light signal that is directed through a fluid sample housed in a sample cell. The input light signal may originate from a plurality of light sources. An output light signal from the sample cell is then routed to one or more spectrometers for measurement of the represented wavelengths in the output light signal. The output of the spectrometers is then compared to known values for hydrocarbons typically encountered downhole. This provides insight into the composition of the sample fluid. Additionally, the light from the light sources can be routed directly to the one or more spectrometers to be used in calibration of the system in the high temperature and noise environment downhole.Type: GrantFiled: January 26, 2006Date of Patent: May 27, 2008Assignee: Schlumberger Technology CorporationInventors: Stephane Vannuffelen, Akira Kamiya, Masaki Miyashita, Kentaro Indo, Reinhart Ciglenec, Tsutomu Yamate

Patent number: 7154411Abstract: A remote sensing unit for sensing subsurface formation is provided. The remote sensing unit is an active device with the capability of responding to control commands to determine subsurface formation characteristics, and transmitting corresponding data values. Some embodiments of the remote sensing unit include a battery, or a capacitor for storing charge. The embodiments that include the capacitor receive RF power that is converted to a DC signal for storing charge on the capacitor. When the charge is depleted to a specified point, the remote sensing unit prompts the wellbore tool to transmit additional RF power to recharge the capacitor. The remote sensing unit is provided with RF power to wake it up and to place it into an operational mode, and/or to send modulated data values that are then transmitted to the surface where operational decisions for the well may be made.Type: GrantFiled: May 28, 2002Date of Patent: December 26, 2006Assignee: Schlumberger Technology CorporationInventors: Reinhart Ciglenec, Jacques R.

A piston is positioned in the chamber and has a rod extending into the opening. The piston is movable between a closed position with the rod filling the opening, and an open position with the rod retracted into the chamber to form a cavity for receiving downhole fluid. A sensor is positioned in the rod for collecting data from fluid in the cavity. The apparatus may also be provided with a probe and/or hydraulic circuitry to facilitate the collection of data.Type: GrantFiled: February 18, 2003Date of Patent: January 17, 2006Inventors: Reinhart Ciglenec, Albert Hoefel
