Weatherford awarded alternate path technology license by ExxonMobil
HOUSTON -- ExxonMobil Upstream Research Company has awarded Weatherford International Ltd. a limited international license for the company’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. Alternate Path 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.
The Alternate Path license allows Weatherford to produce and deploy Alternate Path technology for ExxonMobil affiliates around the world and for ventures in which ExxonMobil participates.
