The RSLH 650 retrievable, mechanically set scab liner hanger is typically deployed after formation shifting in thermal wells to suspend heavy-wall casing joints across damaged zones and prevent complete collapse of the wellbore.

This hanger is designed to reduce your operating costs by minimizing the length of casing required to repair damage. It is ideal for thermal heavy oilproducers where formation shifts have caused casing damage. 

The large internal diameter of the RSHL 650 hanger allows passage of standard size tubulars, and retrieval is accomplished through use of standard fishing equipment and procedures.

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 design
• Top and bottom anchoring slips
• Retrivability with standard tools and spears
• NACE MR0175 compliance for environments containing H2S

Rated to 343 degC [650 degF]
