Anchor–Linear Actuator Tool
ReSOLVE Family instrumented wireline intervention services
Employ controlled high-force linear actuation with high-expansion anchoring capability.
Precise, versatile cutting for various downhole well intervention applications
In all well stages, slot cutting services are critical and required for enabling through-tubing pressure equalization, fluid circulation, and production enhancement for wells completed with sand screens. A high number of cuts may be required in a wide variety of casing types, grades, and potentially extreme downhole conditions.
The ReSOLVE iX™ intelligent extreme wireline intervention service has been customized for an extreme-performance slot cutter application. This instrumented and surface-controlled, nonexplosive mechanical slot cutter is an alternative solution to conventional explosive tubing punchers or other mechanical punchers, expanding the operational capacity of downhole cutting and perforating methods for increasingly complex well designs.
The award-winning ReSOLVE iX slot cutter consists of a scissor-opening assembly with a rotatable cutting blade on one arm, with a fixed anchor to stabilize the other.
The slot cutter configuration is extremely versatile, letting you combine up to eight slots simultaneously and up to 200 slots in a single run while maintaining cutting efficiency. The tool seamlessly combines with other intervention services, including logging, cleaning, cutting, and milling, as well as other mechanical intervention and production logging tools for combining multiple operations into one run.
The cutting process is controlled by using hydraulic pressure to open the cutter arms, with progress monitored in real time and the maximum depth of cut depending on the selected blade design. Controlling the precise cut depth and confirming completion significantly reduces the risk of damaging control lines or the annular tubing.
