Downhole Products' Expand-O-Lizer ‘Standard Service’ is a one-piece semi-rigid bow type centralizer, manufactured from spring steel to allow for a degree of flex when passing gauge hole applications, where the operator is concerned that swelling/shifting shales are present that could impede a solid blade centralized string from getting to T.D.
Features/Benefits
Non-welded, robust one piece design
Suitable for rotation due to axial rigidity
Restoring forces up to 3 times greater than API
Spring steel flexible design significantly reduces running forces and allows easy passage through well-bore obstructions
Gauge hole OD offering maximum stand-off
Suitable for onshore installation reducing rig time costs and HSE exposure
Options
Dedicated engineering support team
Centralizer placement / T&D analysis available upon request
Sizes range 2-7/8” - 20”
New sizes designed and tested within two weeks
