Unconsolidated zonal isolation and control |
摘要 |
A system for enhancing oil production and reducing contamination thereof by such things as water breakthrough in unconsolidated horizontal wells comprises gravel packing, zonal isolation and selective flow control in combination. The significant control provided by the system enables the well operator to create a uniform pressure drop form heel to toe of the horizontal well and avoid commonly experienced water coning and early breakthrough at the heel of the horizontal borehole. |
