IMAGING


Washpipe Conveyed SpectraScan Imaging
Introduction
One of the
major advantages of memory logging devices is that they can
be deployed by a variety of mechanisms. The patented
SpectraScan® Imager can be deployed with slickline, coiled
tubing, electric wireline, and can now be washpipe-conveyed.
The tool is calibrated and run downhole inside the washpipe
to a point at or below the sump packer. The tool
"idles," awaiting the start of the frac-pack
procedure. At the preprogrammed time after the tool is
placed downhole, or through the use of a time delay after
the tool’s pressure gauge recognizes the procedure has
begun, the tool begins recording data to memory. The
washpipe or workstring is tripped out of the hole during the
recording so that a SpectraScan® Image is obtained as the
tool passes the stimulated interval. No additional rigtime
or logistical effort needs to be expended, which leads to
substantial savings in time and money in the deepwater
arena.
The Washpipe-Conveyed
SpectraScan Imager, depicted to the right, illustrates the
memory SpectraScan tool placed at or below the sump packer
with a perforated sub used to communicate bottomhole
pressures to the pressure gauge at the bottom of the SpectraScan Imager.
