Open Hole Ball-Drop Multi-Stage Fracturing
Provide immediate efficient seal, whatever the fluids or the temperature cycles*
Openhole isolation is challenging, especially with irregular borehole geometries. With the high flow rates used during hydraulic stimulation, the temperature can drop in elastomer sealing elements, causing thermal contraction and leaks.
Saltel Steel FracPacker has no moving parts and is set almost instantly by pressuring-up the casing.
The strong mechanical structure will allow the string to be rotated, reciprocated and together with the large clearance will avoid any damage running in hole. The self-centralization will reduce the number of centralizers.
The steel packer will also be able to self-adapt to irregular borehole geometry, and to re-energise as soon as pressure is used in the interval. A pressure compensation system improves the seal as the frac pressure increases.
