Although water injection has improved recovery in vertical wells, they are still inefficient.
This diagram illustrates the waterflood pattern from a vertical injection well to a vertical production well. The red areas represent bypassed oil.
This diagram illustrates the waterflood pattern from a horizontal injection well to a horizontal production well.
Varying reservoir permeability and pressure drops within the horizontal well mean that oil is still bypassed.
SmartWell® Solution
A combination of SmartWell® and horizontal well technology enables:
Balanced water injection, resulting in higher pressures that force more water into the lower permeability intervals
Effectively-managed production, with drawdowns balanced to ensure the even advance of the flood front, achieving the most efficient sweep possible
This diagram illustrates the waterflood pattern from a horizontal injection well to a horizontal production well with both wells using SmartWell® technology to regulate flow.
Varying reservoir permeability and pressure drops within the horizontal well can be accommodated and managed, delivering the most effective possible sweep.
