SpecialReport: Completion Technology
Upon flowback, the shallow interval was
responsible for the highest water and oil
returns. Figure 6 shows the returns from
the three-interval treatment. Since all of
the intervals were subjected to the same
acid treatment, the PGT diagnostics were
able to determine which interval contributed
the highest returns of water and
oil tracer. This would have not been possible
by batch tracing the acid on surface.
PGT provides a way to inject tracers
down to the cluster-level of resolution. It
is a highly versatile technology that can

SQUIRES
Chris Squires is the regional engineering adviser for ProTechnics, a division of Core Laboratories, in
Pittsburgh. He works with operators to interpret the results of tracer diagnostic projects used to evaluate
completions designs and hydraulic and hydrocarbon communication between wells. Squires started working
in the energy industry in 2007 as an engineer for the cementing, fracturing and acidizing business units for
Halliburton Energy Services in the Appalachian Basin. Squires then worked as the senior completions engineer
for Consol Energy (CNX Resources) during the development of its early Marcellus and Utica wells.
He holds a degree in mechanical engineering from Pennsylvania State University.
be used with perforation guns containing
numerous combinations of number of
holes, entry-hole diameters, shaped charges
and phasing. It is especially well suited
for scenarios such as refracturing or highintensity
perforating, where multiple open
clusters of perforations are subjected to
the same treatment fluids. Without PGT,
a determination of which clusters are returning
the most oil or water and which
clusters may not be returning at all would
require permanent monitoring hardware
or an intervention for production logging.
In addition, PGT also can be used to
obtain flow assurance, well-to-well communication
and even FDI diagnostics.
The tracers inside the PGT system are
shelf-stable and can be stored and used
when ready, and do not require a dedicated
on-site representative.

Technical Conference & Exhibition.
