Cost-Benefit Analysis of Sleeve Stabilizers and Integral Stabilizers

Upfront Cost
·Integral stabilizers are cheaper per unit but must be entirely replaced once worn or damaged.
·Sleeve stabilizers have a higher initial cost due to their modular design but offer extended usability.

Maintenance & Lifespan
·Sleeve stabilizers allow for sleeve-only replacement, reusing the mandrel multiple times.
·Integral tools are one-time-use per section or hole condition.

Logistics & Inventory
·Sleeve stabilizers reduce storage needs—operators can carry a smaller number of mandrels and multiple sleeve types.
·Integral stabilizers require carrying many full-size units for various hole sizes or formations.

Field Data Snapshot
In a West African offshore project:
·Switching to sleeve stabilizers led to 22% cost savings over 9 wells.
·Tool turnover dropped by 30%.
·Maintenance-related NPT (non-productive time) decreased by 18%.

When viewed holistically, sleeve stabilizers deliver strong long-term economic benefits, particularly in multi-well or extended-reach campaigns.
