Increased completion of ultra-deep,high-pressure and high-temperature wells is driven by the growing demand for hydrocarbons.Extreme pressure frac screens(XPFS)have been developed to handle the higher loads and conditions.An XPFS is a high-pressure-rated sand control screen capable of withstand-ing up to 15 ksi burst and collapse.The XPFS utilizes engineered,high-strength disintegrating materials (HSDM)to operate as a fluid-loss barrier that can be run-in on the liner.This new technology combines ease of use with a controlled delay in the activation that opens the screen to flow.The HSDM covers and seals over a bonded bead matrix that,when the HSDM dissolves,acts as a screen equal in filtration performance,but better than current sand control alternatives in its erosion resistance.The beaded matrix can be customized to ensure filtration through a wide range of particulate sizes and prevents passage of 85 to 90%of all particulates larger than 53 m.The HSDM covering the beaded matrix is formulated to corrode in the presence of brine and/or acid and provide access to the sand control media,enabling normal well production.The system increases the efficiency of hydraulic fracturing treatments,and can be installed in a steerable drilling liner.Alternatively,the beaded matrix can be replaced with a solid HSDM plug,thus acting as a fluid-loss friendly;solid-base pipe during run-in and leaving a pre-drilled liner after the HSDM dissolves,eliminating the expensive need to later perforate the pipe.This paper presents the pressure rating,dependability,and sand control capabilities of a liner that provides operators with an interventionless ability to complete ultra-deep,high-pressure high-temperature wells.
