Quartz Pressure & Casing Collar Locator

Quartz Pressure & Casing Collar Locator

Depth correlation and pressure measurement. The QPC is a short combination tool consisting of two sensors: a quartz pressure sensor and a CCL (Casing Collar Locator).

APPLICATIONS

The CCL is a depth correlation tool. The tool responds to changes in tubing metal volume, and can detect collars and indicate perforations or damage. The pressure sensor consists of a quartz crystal and is used for downhole flowing and shut-in pressure measurements. The QPS is also a quartz sensor measuring the wellbore pressure. The tool is used as a second pressure sensor in the toolstring and has the same specifications as the pressure sensor in the QPC-tool.

KEY FEATURES

• Depth correlation
• Location of severe casing or tubing damage
• Confirmation of perforation depths
• Combinable with other GE Ultrawire™ tools
• Memory or surface read-out operation

Pressure data can be used to:

• Determine the efficiency of the well and the performance of the reservoir
• Convert flow rates from down hole to surface conditions
• Monitor well stability
• Estimate density (fluid identification)
