Abstract

Inflow control devices, (ICD's) are used in horizontal sand control applications to delay the onset of water and gas coning. ICD's function by restricting the inflow at multiple locations into a horizontal completion to minimize localized regions of low pressure where gas or water may "break-through" and dominate the production flow regime. The restricted access from the sand control filter to the base pipe in ICD-equipped screens offers an ideal geometry in which to include a temporary plug. Once plugged, an ICD-equipped screen is hydraulically identical to production tubing, allowing hydraulic operations, such as circulating or setting open-hole packers, to be conducted. It is envisioned that the temporary plug used in ICD-equipped screens would be comprised of one of the soluble sealing polymers being developed
