Downhole video involves lowering a
camera downhole on a well and viewing the images in real time. Critical
information can be readily obtained such as:
the exact location of reservoir
fluids
the fluid turbulence and flow
direction
the deterioration of the water
quality
The rock fractures
and faults
A part of the above applications, the
downhole video method can be used to identify the presence of
different type of deteriorations occurred in a water well. These
deteriorations can be caused from:
Biofouling (the growth of
bacteria in the filter screens)
Broken casing
Sand problems
etc ...
Based on the principle "One
picture is a thousand words" this method can give solutions to all
difficult water well operations.
