Alternate PathTM technology for gravel packing services ensures full gravel pack in cased and openhole completion wells
Improves long-term reliability of sand control and reduces workovers
Developed and licensed by ExxonMobil Upstream Research Company
HOUSTON – ExxonMobil announced today that it has awarded Baker Hughes Incorporated a limited international license to ExxonMobil’s Alternate Path technology patent portfolio for services of gravel packing cased and openhole completion wells. Alternate Path technology was developed and patented 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 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 well packing license allows Baker Hughes to produce and deploy Alternate Path technology and gravel packing services for ExxonMobil affiliates around the world and for projects in which ExxonMobil has an interest. “Alternate Path technology uses a field-proven design that is widely accepted by the industry,” said Zac Crouch, vice president, completions and wellbore intervention at Baker Hughes. “The screens extend our robust sand control portfolio, which helps operators reduce uncertainty and maximize sand-free production. We are pleased to partner with ExxonMobil through this license agreement.”
