SITAN MP43-CGW casing collar location/temperature/gamma ray logging tool for production logging operates as part of a tool string and derives power and control from a suitable system controller. The sensor of the temperature is a platinum resistance wire housed in an Inconel needle and measure the borehole fluid temperature. SITAN MP43-CGW casing collar location/temperature/gamma ray tool is fast reacting, accurate,stable and repeatable. SITAN MP43-CGW casing collar location/temperature/gamma ray tool comprises a Sodium Iodide scintillation crystal and photomultiplier to measure incident gamma radiation. This detector is unshielded and will thus accept radiation from any direction. The device responds to changes in metal volume such as at tubing collars and perforations. The line conductor passes through the tool from upper to lower heads.
Application:
1. Depth control in casing or tubing
2. Location of casing or tubing damage
3. Confirmation of perforation depths or intervals
4. Lithology Identification
5. Depth Correlation.
6. Location of fluid entry, gas leaks and injection zones.
