SecureTrac Compact Casing Shoe System
Maximize Efficiency in Unconventional Completions
The economics of unconventional wells demand a high degree of operational efficiency. The conventional option for stimulation remains pump-down operations which remove the need for a coiled-tubing unit or wireline tractor at the beginning of the fracturing operation as well as the extra costs and risks associated with those technologies.
For pump-down operations to be effective, communication with the formation is essential. You have multiple options available for creating a flow path at the toe of the well to enable the pump-down operations.
The Weatherford SecureTrac™ compact casing shoe system maximizes reservoir exposure while maintaining well integrity. Compared with other techniques for establishing communication with the formation, this innovative system minimizes the risk of mechanical failure and continues to function as a well barrier until the well is perforated.

Well Integrity
Designed with well integrity at the forefront to provide a gas-tight barrier even at low differential pressures.
Four independent Sure-Seal® 3 valves provide a gas-tight barrier even at low differential pressures.
Rated to 15,000 psi (103 MPa) and 400°F (204°C), the SecureTrac casing shoe system overcomes the challenges associated with unconventional wells, ensuring well integrity even when exposed to pressure from nearby wells undergoing stimulation work.
Operational Efficiency
The integral design shortens the length of the casing shoe as compared to conventional shoe tracks, increasing overall well efficiency and productivity.
Latch-in plugs ensure a positive pressure signal at the surface of full displacement and formation communications.
The integral design shortens the length of the wet compact shoe as compared to conventional shoe tracks, maximizing the length of the productive hole and increasing overall well efficiency and productivity.
Optimal Design
Extensive computational fluid dynamics simulations optimize laminar flow and decrease fluid velocities to reduce erosion and minimized back pressure.
Coupled with the proven Sure-Seal 3 valves and the internal steel components, the SecureTrac system’s optimal design exceeds the requirements of API 10F and retains full functionality and sealing ability even after circulation at rates of 10 barrels per minute for up to 62 hours and more than 1,100,000 lb equivalent sand content.
