Hydraulic activated тое sleeve with isolation valve
Max OD in:
5.500
Liner size in:
4.500
APPLICATION
Hydraulic Activated Тое Sleeve with lsolation Valve is designed to bе used as а first stage for multistage hydraulic fracturing. Hydraulic activated Тое Sleeve in terms of construction consists of an activation sleeve and а toe sleeve.
- Uncemented casing / liner applications.
- Vertical, directional and horizontal wells
- Acid-resistant design of all assembly elements (HCL 14%).
- Lock mechanism that prevents spontaneous closing of ports.
- Withstands high tensile loads and high differential pressures.
- Саn bе milled out after operations providing the fullbore ID.
- Re-closaЫe Тое Sleeve.
OPERATIONS SEQUENCE
- Activation Ball is pumped down to the landing seat to achieve bump pressure.
- After pressure increasing the inner sleeve is sheared down to close circulation ports in activation valve.
- Provide well casing and Тie-back Seal Assembly stab in.
- lncrease pressure to the desired value to open the circulation frac ports.
SUPPLY PACKAGE
- Hydraulic Activated Тое Sleeve with isolation valve.
- Activation Ball - primary.
- Activation Ball - back-up.
