Patent number: 6627873Abstract: A logging while drilling and wire line system for analyzing the concentration of carbon dioxide or another substance, in a sample down hole in a bore hole. A chamber is filled with a sample that may be fluid, or condensate and gas. The interior chamber volume is selectably expandable for decompression of the sample. The sample may alternately be decompressed by allowing a sample at formation pressure to enter the chamber at a lower pressure, thereby decompressing the sample. A sensor measures the absorbance, transmittance or attenuated total reflectance of the infrared light. Mid and near infrared light is utilized to identify carbon dioxide, water and a plurality of hydrocarbons. A wiper cleans the transmitter and sensor between readings to reduce measurement error caused by fluid sample contamination.Type: GrantFiled: April 16, 2001Date of Patent: September 30, 2003Assignee: Baker Hughes IncorporatedInventors: Borislav J. Tchakarov, Rocco DiFoggio, Stanislav W. Forgang, Otto N. Fanini, Marcelo F. Civarolo, James C. Hunziker

Patent number: 6218662Abstract: A logging tool system for analyzing the carbon dioxide concentration in a fluid sample downhole in a borehole. A chamber is filled with the fluid sample and is closed to isolate the fluid sample from the borehole. The interior chamber volume is expanded to decompress the fluid sample, and a transmitter discharges light in the mid-infrared range. A sensor measures the absorbance of mid-infrared light by the decompressed fluid sample and generates a signal representing the carbon dioxide concentration. Mid-infrared light absorbance in the range between 4.1 and 4.4 microns can be analyzed by the processor to identify the carbon dioxide concentration in the fluid sample, and infrared absorbance in the mid-infrared range between 3.2 and 3.6 microns can be analyzed to identify methyl and metheylene components. A wiper cleans the transmitter and sensor between readings to reduce measurement errors caused by fluid sample contamination.Type: GrantFiled: April 23, 1998Date of Patent: April 17, 2001Assignee: Western Atlas International, Inc.Inventors: Borislav J.

Patent number: 6116337Abstract: An articulated connector for providing electrical insulation between downhole well equipment such as logging sondes suspended by a wireline. Articulated joints are connected to the well equipment to provide for the desired movement, and the joints are connected by a central housing. The housing is configured so that a nonconductive element interrupts electrical conductivity through metallic components of the housing. The housing uniquely combines with the articulated joints to provide an articulated connection between the well equipment while providing electrical insulation therebetween.Type: GrantFiled: June 17, 1998Date of Patent: September 12, 2000Assignee: Western Atlas International, Inc.Inventors: Marcelo F.

Patent number: 5411106Abstract: A method and apparatus for acquiring a plurality of sidewall cores from an earth formation intersected by a wellbore while a coring tool is located downhole. A sidewall coring tool is provided having an internal core receptacle for receiving and storing sidewall cores in serial orientation. The coring tool incorporates a movable bit box providing rotary support and linear coring and retracting movement of a rotary coring bit. A bit box tilting and rotation actuator is incorporated within the coring tool for achieving breaking at the core sample from the formation and for selectively positioning of the bit box and rotary coring bit at a coring position where the bit is oriented in normal relation with the axis of the wellbore and a core ejecting position where the rotary coring bit is positioned in registry with the internal core receptacle for deposit of cores in serially oriented relation therein.Type: GrantFiled: October 29, 1993Date of Patent: May 2, 1995Assignee: Western Atlas International, Inc.Inventors: Jacques Maissa, Marcelo F.
