Gravel packing long

wells is no easy task.
As openhole wellbores increase
in size and complexity, so do
gravel-pack operations.
When operating in high-cost offshore
applications or in small field developments,
achieving a complete and uniform gravel pack
is crucial to avoiding sand control failure, and
helps ensure sustainable, profitable wells.3 Your investment isn’t the only thing at risk. Gravel-pack systems have evolved to include Systems with secondary flow paths are complicated secondary pathways to help carry slurry past and time consuming to rig up, and viscous fluids wellbore obstructions. And viscous fluids help cause voids, add operational requirements, and keep proppant suspended during pumping to increase health, safety, and environmental (HSE) enhance pack efficiency.
