Vigor Composite Cement Retainer

Vigor Composite Cement Retainer is a nonmetallic high-quality tool used primarily for cement squeezes. It has multiple uses, including primary and remedial cementing, well control, and temporary abandonment, thereby eliminating storage requirements if separate tools were required for each operation.

The composite retainer exhibits dramatically decreased removal times compared to standard cast iron retainers, resulting in longer bit life and decreased casing wear due to removal. This is achieved by the nonmetallic composition of the retainer, which provides faster drillability without sacrificing performance. The high-tech materials that make up the components of the composite retainer resist corrosion, are lightweight, and ensure a longer life in high-temperature wells. No adhesives are used to connect its components during construction.

The composite retainer easily converts to a bridge plug. The mating surfaces at the top and bottom of the plug rotationally lock drilled-out remnants, decreasing drillout time.

Fluid mixing in a wellbore can lead to a range of undesirable consequences, including the contamination of production fluids, compromised reservoir pressure, and the potential for wellbore damage. Cement retainers act as a barrier to prevent the migration of fluids between zones, ensuring that the produced hydrocarbons remain uncontaminated and maintaining the reservoir's natural balance. By halting the flow of water, gas, or other fluids across different formations, cement retainers contribute to the preservation of reservoir characteristics and the overall economic viability of the well.

- Compact design with high-pressure resistance.

- Easy drillability and milling.

- Single-trip operation enhances efficiency and reduces costs.

- Reliable bidirectional anchoring and sealing performance.

Vigor Composite Cement Retainer is run in conjunction with a setting tool and an insert pipe attached to the tool's front end. The insert pipe's inner bore is

equipped with a sliding sleeve valve, which is opened or closed by applying pressure from the work string via a drop ball, allowing bidirectional pressure control.

- Upon reaching the target depth, the squeeze path remains open for circulation.

- Before setting, a ball is dropped onto the sliding sleeve seat to seal the passage.

- When the applied pressure reaches a predetermined value, the retainer sets, and the sliding sleeve opens, initiating cement or plugging agent injection.

- After injection, the insert pipe is retrieved, and its front-end sealing plug closes the lower passage, isolating the cement/plugging agent below the retainer from the pressure and well fluids above.
