Sand screen isolation
Splitting long lengths of the annulus into shorter sections to improve flow control and prevent sand migration. Challenge Horizontal completions are becoming more extended and more sophisticated, often through different formations….
Turn the reservoir into selective producing zones for better control Challenge When you need to isolate producing zones for selective EOR purposes, the annulus can be sealed and divided into selective producing…
Compartmentalized isolation with annulus packers for selective acid stimulation Challenge Matrix acidizing requires precise flow and pressure control. Saltel Expandable Steel packers placed along the casing string to split the long…
Horizontal completions are becoming longer and more sophisticated, often through different formations. Different openhole completions are being used, with many types of slotted pipe or sandscreens, often combined with sophisticated ICD’s.
To isolate “wet” zones or to segment the production zone to be able to modify the production profiles and shut-off potential water or gas breakthrough, it is essential to create an effective barrier between completion and borehole without using cement.
