MULTI-STAGE SLEEVE SYSTEMS
Field-proven ball-drop and next-gen collet-actuated sleeves for flexible completion designs.
Multi-Stage Sleeve Systems are engineered to streamline hydraulic fracturing operations in horizontal wells by enabling controlled, zone-by-zone stimulation without the need for wireline intervention or plug-and-perf techniques. These systems offer a cost-effective, time-saving alternative for operators seeking precision and operational efficiency in open or cased hole applications.
Ball-Drop Sleeves
Ball-drop systems utilize a progressive, toe-to-heel activation sequence, where each Ball-Open Frac Sleeve is opened by a precisely sized ball dropped into the wellbore. Once the ball lands on its designated seat, applied hydraulic pressure shifts the inner sleeve to establish communication with the annulus. This opens the flow path and initiates the fracturing treatment for that specific zone. Known for their simplicity and reliable mechanical actuation, ball-drop sleeves are ideal for operations requiring predictable, sequential stimulation.
Collet-Actuated Sleeves
Collet-actuated sleeves are designed for precision activation using coiled tubing or shifting tools. These sleeves incorporate a collet mechanism that selectively engages with each sleeve in the well, allowing operators to mechanically open individual sleeves without the need for ball drops or pressure differentials. This method is especially advantageous in wells with complex geometries, limited pressure windows, or when selective stimulation is required after drilling and logging.
Together, these sleeve systems offer tailored solutions for various well conditions—whether you need rapid, pressure-driven actuation or precise, tool-based zone access.
