DRILLING, COMPLETION AND MECHANICAL: PIPE RECOVERY

• Free Point Indicator Tool (FPI)
  The Free-Pipe Indicator (FPI) instrument is part of a system used for recovering free drill pipe/casing/tubing that is stuck in a borehole. The primary function of the instrument is to find the free point; i.e., the downhole location where the drill string or tubular is not stuck. After the free point has been found, the FPI system can be used to separate the free portion of the string from the stuck portion. One procedure utilizes the Free-Point instrument to detonate an explosive charge at the collar immediately above the free point.
• MagTec Free Point (FPI-C)
  The Magna-Tector™ instrument provides highly sensitive and accurate measurements of both stretch and torque movement in a string of stuck pipe. The measurements are transmitted through a conductor cable to a surface panel. This instrument accurately locates the lowest point from which a string of pipe; e.g., drill pipe, casing, or tubing, can be successfully recovered.
• TriMag Free Point (FPI-D)
  The TriMag-Tector™ instrument provides highly sensitive and accurate measurements of both stretch and torque movement in a string of stuck pipe. The measurements are transmitted through a conductor cable to a surface panel. This instrument accurately locates the lowest point from which a string of pipe; e.g., drill pipe, casing, or tubing, can be successfully recovered.
• Free Point Indicator Tool - Nautilus HPHT (FPI-HPHT)
  Nautilus is Baker Atlas' range of high pressure and high temperature logging instruments, designed for performance and reliability in the most extreme conditions. New exploration horizons are extending the limits of borehole depths. As these limits are extended, the pressures and temperatures encountered become more challenging. Nautilus Hostile instrumentation is available for conditions up to 500 degrees F (260 deg C) and up to 30,000 psi (206 MPa). Nautilus delivers high-pressure, high-temperature reliability and performance, coupled with the measurement integrity and accuracy already delivered by our standard range of instrumentation. To qualify for the NAUTILUS signature, instruments must be rated above 400 deg F (204 deg C) and/or 20,000 psi (137.9 MPa). To find out if Nautilus HP, HT or HPHT instrumentation will meet the challenge of your next ultra hostile well, speak to a Baker Atlas representative.
• Spring Tector Free Point (FPI-B)
  The Spring Tector instrument employs a microcell that accurately measures both stretch and torque movement in a string of stuck pipe and transmits the measurements through a conductor cable to a surface panel.
• Pipe Recovery Log (PRL)
  The Pipe Recovery Log is an acoustic measurement using a 3-ft-spaced transmitter and receiver configuration. Acoustic pulses initiated at the transmitter travel down the pipe and are measured at the receiver. The energy level of the acoustic waves at the receiver is proportional to the degree of sticking. Similar to conventional cement bond log measurements, low attenuation readings indicate free pipe and high attenuation readings indicate stuck pipe.
• String Shot Back-Off (BO)
  This wireline-conveyed pipe recovery tool uses a precise quantity of explosive detonating cord to produce shock waves.
• Jet Cutter-Tubing and Casing (JCS)
  Jet cutters are available for severing practically any size downhole tubing, drill pipe, or casing. The cutting action is produced by a circular-shaped charge. This type of cutter typically leaves a flare on the severed pipe string. In order to perform subsequent pipe recovery operations, it is necessary to smooth the top end of the fish with an internal mill, usually run with an overshot. Caution should be exercised while running the jet cutter to avoid damage to adjacent tubing and casing strings and to minimize debris that could hinder subsequent wireline operations.
• Chemical Cutter (CCS)
  The chemical cutter has been successfully used in pipe recovery operations for many years. This tool will cut through tubing, casing, or drill pipe in a fraction of a second without damaging an adjacent string. The cut is flare-free, burr-free, and undistorted. This allows easy engagement of an overshot without having to dress the fishtop.
• Electromagnetic Fishing Tool (EMT)
  The Electromagnetic fishing tool is designed to recover metallic (magnetic) debris from cased and open hole wellbores, such as drill bit debris. The EMT uses a powerful electro magnet focused on a flat surface perpendicular to the tool axis.
