FORMATION EVALUATION: AUXILIARY DOWNHOLE EQUIPMENT

• Temperature, Tension, Resistivity Mud (TTRM)
  The TTRM (Tension, Temperature, Resistivity Mud) sensor sub monitors the tension/compression forces on the downhole instrument string while logging, and provides a better knowledge of the force on the cable- head tensile bar when the tool is sticking. In addition, the sub provides information about forces on the logging string during pipe-conveyed or coiled tubbing operations. It is compatible with the new logging technology as well as with conventional services.
• FOCUS Tension, Temperature, Resistivity of Mud, Accelerometer (FOCUS TTRMA)
  FOCUS, from Baker Atlas, is the latest in high efficiency premium open hole logging systems. All of the downhole instruments have been redesigned, incorporating advanced downhole sensor technology, into shorter, lighter, more reliable logging instruments, capable of providing formation evaluation measurements with the same precision and accuracy as the industry?s highest quality sensors, at much higher logging speeds. Logging speeds are up to twice the speed of conventional triple-combo and quad combo logging tool strings. The logging system consists of the four standard major open hole measurements (resistivity, density, neutron, acoustic) plus auxiliary services.
• Orientation Tool (ORIT)
  The Orientation Tool is a general purpose borehole orientation instrument. It continuously establishes the position of the toolstring with respect to vertical and magnetic north.
• Cable Head Tension (CHT)
  The CHT (Cable Head Tension) sensor sub monitors the tension/compression forces on the downhole instrument string while logging, and provides a better knowledge of the force on the cable- head tensile bar when the tool is sticking. In addition, the sub provides information about forces on the logging string during pipe-conveyed or coiled tubing operations. It is compatible with the new logging technology as well as with conventional services.
• FOCUS Two Arm Caliper (FOCUS TAC)
  FOCUS, from Baker Atlas, is the latest in high efficiency premium open hole logging systems. All of the downhole instruments have been redesigned, incorporating advanced downhole sensor technology, into shorter, lighter, more reliable logging instruments, capable of providing formation evaluation measurements with the same precision and accuracy as the industry?s highest quality sensors, at much higher logging speeds. Logging speeds are up to twice the speed of conventional triple-combo and quad combo logging tool strings.

• Well Geometry Instrument (WGI)
  High-resolution and Versatile Six-arm Caliper Measurement Service
  
  The Baker Atlas Well Geometry Instrument^SM (WGI^SM) measurement service brings a new dimension to open-hole caliper measurements by acquiring high-resolution data while running in and out of the hole.
• 3-Arm Caliper (3CAL)
  The Caliper Log is a continuous profile of the borehole wall showing variations in borehole diameter. Caliper Logs can be recorded using 2-, 4-, or 6-arm instruments. These measurements and their average accurately define the hole shape and size, especially in deviated and elliptically shaped holes.
• 4-Arm Caliper (4CAL)
  The Caliper Log is a continuous profile of the borehole wall showing variations in borehole diameter. Caliper Logs can be recorded using 2-, 4-, or 6-arm instruments. These measurements and their average accurately define the hole shape and size, especially in deviated and elliptically shaped holes.
• 6-Arm Caliper (6CAL)
  The Caliper Log is a continuous profile of the borehole wall showing variations in borehole diameter. Caliper Logs can be recorded using 2-, 4-, or 6-arm instruments. These measurements and their average accurately define the hole shape and size, especially in deviated and elliptically shaped holes.
• PCL Equipment (PCLS)
  High-angle, extended reach, and horizontal drilling technologies have created new requirements for the conveyance of wireline logging instruments. Even in straight-hole drilling, difficult hole conditions such as washouts, bridges, key seats, dog legs, etc., present obstacles to standard wireline methods.
