In the Silvertip field, where Schlumberger completed Perdido’s first two development wells, the narrow pressure window is so low that conventional open-hole gravel pack treatments would be at risk.

The cased hole, by application, is expected to be the largest market from 2020 to 2025 The report segments the sand control solutions market, by application, into open hole and cased hole.

An extensive test program to evaluate a concentric annular packing system (CAPS) also expanded knowledge of horizontal gravel packing.

Perforation Cased-hole completions require casing to be run into the reservoir. In order to achieve production, the casing and cement are perforated to allow the hydrocarbons to enter the wellstream.

The hole is currently cased to a depth of 1200 meters (4000 feet), and efforts are underway to wedge through casing to test bedrock at an estimated depth of 1280 meters (4200 feet).
