Frac Safer with expandable steel open hole Packer
Challenge
Openhole multistage (OHMS) fracturing guarantees improved production rates and recovery in various types of reservoirs. Important criteria affect the results of OHMS stimulation. Among numerous factors, the choice of the open hole packers is critical.
Solution
Specially designed for OpenHole Multistage Fracturing, Saltel Expandable Steel FracPackers are a simple alternative to existing solutions.
Saltel Xpandable Packers provide
- high-pressure differentials
- high-temperature ratings
- short-length designs in 2.5ft, 4ft and 8 ft
- Reduced running diameter with no ID restriction to be run in long horizontals.
The expandable metal sleeves are expanded between the casing and the borehole by applying pressure in the casing, sealing is immediately achieved after expansion, and the well is ready for selective stimulation.
