HOUSTON--(BUSINESS WIRE)--Nov. 20, 2014--
ExxonMobil Upstream Research Company has awarded Delta Screens &
Filtration LLC a limited international license to ExxonMobil’s Alternate
Path technology patent portfolio for gravel packing cased and openhole
completion wells.
Alternate Path is a patented technology developed by ExxonMobil to
improve the reliability of wells completed in sand-prone reservoirs. The
technology provides alternate flow paths called shunt tubes in the
downhole tool used for packing gravel in the producing sections of a
well. The shunt tubes enable the Alternate Path packing operation to
continue when sand prematurely blocks the well annulus, which would stop
a conventional packing operation. The shunt tubes divert the gravel
slurry around sand blockages and through distributed portholes to fill
voids in the annulus until a complete pack is in place.
“Alternate Path technology is one of several sand control completion
technologies developed by ExxonMobil to improve reliability of
sand-prone production wells,” said Sara N. Ortwein, president of
ExxonMobil Upstream Research Company. “When the geology and the
economics of a development call for openhole completions, Alternate Path
technology is the technique preferred by ExxonMobil.”
The Alternate Path license allows Delta Screens to produce and deploy
Alternate Path technology for ExxonMobil affiliates around the world and
for ventures in which ExxonMobil participates.
“Alternate Path technology gives us a more reliable way to gravel pack
wells where we need sand control,” said Delta Screens President, Richard
Grifno. “Alternate Path is field proven and we’re very pleased to be
approved as a licensee for ExxonMobil.”
