• Hydraulically opening with internal pressure with no free fall opening device
• Not dependent upon hole geometry or mud properties to operate
• After closing no forces are applied to the tool which would open it again
• PDC drillable materials with high tech aluminum
• Emergency system allows tool to open mechanically with the use of a free fall opening device or opening plug
• High strength body lock ring prevents tool from reopening once its closed even while fracturing the formation
• Adjustable opening pressure
• Unique hydraulic method is disabled against the closing sleeve until closing plug is landed preventing premature closure
• Standard API threading available
• Superior Burst and Collapse
• Anti Rotation feature speeds drill out time
• Can be opened immediate upon completing first stage cementing
• Short internal aluminum sleeve and closing plug required to drill out after cementing is complete
• Tool is full opening after drill-out
• No internal lips to hang up retrievable packers after drill out
• Cannot be accidentally reopened
High Pressure
Hydraulic Stage Tool
with External Sleeve
• Used to cement casing in multiple stages
• Applicable in horizontal and deviated well bores and high angle inclination wells
• Allows operators great flexibility in controlling flow rheology, cement chemistry, and downhole hydrostatic pressures
• Used in conjunction with other stage tools for multiple stage cementing
• Often used as the lower stage on a multiple stage well because it requires no free fall opening device to open
• Can be used with Multi-Stage Cementing Swivels
• Used where a single stage cement job would result in breakdown of a weak formation causing cement losses
• Helps prevent contamination of the producing zone
