Cased Hole Logging

GAMMA RAY/GAMMA GUN

Image

The Dialog gamma ray service measures naturally occurring gamma ray levels within the well bore.  Available in both a stand alone service and also in conjunction with our explosives operations, the log is used for identification of the formation lithology.

TEMPERATURE LOG

Image

The Dialog temperature log service records a survey of the wellbore temperature.  The temperature log service is often run in conjunction with a noise log service.

24 Arm Tubing Caliper

Image

The primary function of the 24-Arm Caliper is to detect the deformation, bending, fracture, perforation, rod wear and inside corrosion of tubing or casing with 24 caliper fingers that are in close contact with the inner wall of the casing. All logging data, including 24-channels of borehole diameter is processed by the computer software, the diagram of borehole inner diameter and a 3-D image of pipe are created to intuitively demonstrate the condition in detail of downhole tubing or casing. This caliper measures pipe ID from 1.77″-7.09″.

40 Arm Casing Caliper

Image

The 40 Arm Caliper is a mechanical downhole well logging tool. The primary function is to detect the deformation, bending, fracture, perforation and inner wall corrosion of casing with caliper fingers that are in close contact with the inner wall of the casing. Each caliper finger is connected to an independent non-contact displacement transducer that features small sizes, long service life, and high measurement accuracy. It measures pipe ID from 3.11” to 8.25”. After data is processed by the computer software, the diagram of borehole inner diameter and a 3-D image of the casing are created to intuitively demonstrate the damage details of downhole casing.

56 Arm Casing Caliper

The 56 Arm Caliper is a mechanical downhole well logging tool. The primary function is to detect the deformation, bending, fracture, perforation and inner wall corrosion of casing with 56 caliper fingers that are in close contact with the inner wall of the casing. Each caliper finger is connected to an independent non-contact displacement transducer that features small sizes, long service life, and high measurement accuracy. It measures pipe ID from 3.94” to 9.625” and out to 13.625” with extended length fingers. After data is processed by the computer software, the diagram of borehole inner diameter and a 3-D image of the casing are created to intuitively demonstrate the damage details of downhole casing. 

Spinner LOG

Image

Dialog Wireline’s spinner/temperature survey Production Logging Tools measure reservoir performance, identify fluids, and detect leaks in connections or in situations that are too small to detect by caliper tools. This saves an enormous amount of time in lieu of relocating plugs and packers off tubing.

X/Y OPEN HOLE CALIPER

Image
The X-Y caliper accurately measures two axes of the well bore allowing for an accurate cross-sectional area to be used in flow rate calculations, rather than a nominal diameter that may not be correct.

Cement / Radial bond log

Image
The Dialog Cement Evaluation Service is used evaluate the cement bond and the existence of hydraulic zone isolation.  Depending on the applications, the cement evaluation service is performed with a single receiver bond tool, dual receiver bond tool or a radial bond tool.
