The RSLH-LS long-stroke retrievable mechanically set scab liner hanger suspends heavy-wall casing joints across damaged zones to prevent complete collapse of the wellbore after formation shifting in thermal wells.

It enables tubular movement and rotation during cementing operations and has a large internal diameter to allow passage of standard-size tubulars.

The RSLH-LS hanger is compliant with NACE MR0175 for environments containing H2S, and its setting tool can be adaptable to liner top debris management systems.

Applications

• Remedial operations
• Workover operations
• Thermal heavy oil producers where formation shifts have caused damage to the casing

Features

• Fullbore internal diameter
• Engineered, simple, field-proven desgin
• Top and bottom anchoring slips
• NACE MR0175 compliance for environments containing H2S
