A leaking well can damage the environment and result in production loss. The Noise Tool houses a

sensitive hydrophone that is highly effective in the detection of flow inside and outside the cased well. It

uses a piezoelectric sensor to detect downhole audio frequencies and amplitude variations due to fluid

and gas movement. The audio sound from the tool through a surface module allows the operator to

monitor well conditions.

The Noise Tool is combinable with Cement Bond Tool, Caliper Tool, Metal Thickness Tool, and etc. to offer

clients different service purposes.

Noise interpretation software analyses frequency spectrum, which

provides reference for production evaluation, leak detection and

channel location, etc.

Description

Interpretation Report


Analysis

The stationary logging file shows strong noise around 2890m, and

full frequency range is displayed. This is not a perforated zone and

there is no special structure in the pipe column. Therefore, it is

identified as the leak point.

Result

The interpretation result clearly shows noise frequency spectrum

imaging at 2890m, where there should be the leak point.

Noise Case No. 1: Locating Fluid Loss from Producers

Purpose of the logging is to know the injection into each zone in injection

profile.

Description



Analysis

The stationary logging file shows low-frequency noise is absent from

1005m-1020m, while fairly strong mid-frequency noise is present.

Result

The interpretation result shows noise signals are clearly presented

between the two producing zones, and the frequency falls into that of

behind-casing noises. Therefore, there should be cementing issues ie.

channelling, between the zones.

Noise Case No. 2:

Purpose of the logging is to know the packer effectiveness in injection profile.

Description



Analysis

The stationary logging file shows there is fairly strong noise around 4543m,

where the packer has been deployed.

Result

The interpretation result shows very clear noise where the packer has been

deployed, which means the packer has a problem.

Noise Case No. 3: Packer Effectiveness Testing


Purpose of the logging is to verify sand entry point and proportion in

production profile.

Description


Analysis

Based on stationary measurement documents, it is observed that there are

obvious noise wave above the depth 665m in this well.

Result

The interpretation result shows there is oil and sand entry above 670m,

and sand entry is serious at 600m and 422m.
