In the process of drilling and completing a well for production, it is often necessary to isolate sections of formation. Retrievable tools offer versatile and economical means to isolate portions of the well to perform remedial repairs.
•Multiple operations in one trip
•Variety of tool combinations
•Job flexibility
•Easy to reposition
•Drill out is avoided
•Fluid Placement
•Pressure control
•Zonal Isolation
CHAMP® IV Packer
This is a hookwall-retrievable packer with a concentric bypass. As the tool is lowered into the hole, a J-slot holds the bypass open and controls the setting of the packer. When the packer is set, a balancing piston activated by tubing pressure holds the bypass closed.
Each tool assembly includes a J-slot mechanism, mechanical slips, packer elements, hydraulic slips, and a bypass. Round, piston-like slips used in the hydraulic hold-down mechanism prevent the tool from being pumped up the hole. The bypass allows fluids to pass around the bottom of the tool when it is removed from the hole. This design eliminates accidentally opening a conventional bypass during circulation around the bottom of the packer.
Circulation around the CHAMP IV Packer is not interrupted if the packer element temporarily seals unintentionally, as when it passes through points of interference in the casing.

CHAMP® V Non-Rotational Packer
The CHAMP® V non-rotational packer is ideal for deepwater extended reach situations where getting enough torque down hole to manipulate the toolstring can be a major challenge.
The CHAMP V non-rotational packer consists of a hookwall retrievable packer with a concentric bypass and a continuous indexing J-slot.
Easily operated in extended reach or highly deviated wellbores
Requires no rotation to set the packer—picking the packer straight up (no torque required) opens the bypass
Can be easily relocated to multiple zones during a single trip for treating, testing, or squeezing
Temperature rating of 400°F (204.4°C)
RTTS® Packer
The RTTS® Packer is a full-opening, hookwall packer used for testing, treating, and squeeze cementing operations. In most cases, the tool runs with a circulating valve assembly.
The packer body includes a J-slot mechanism, mechanical slips, packer elements, and hydraulic slips. Large, heavy-duty slips in the hydraulic hold-down mechanism help prevent the tool from being pumped up the hole. Drag springs operate the J-slot mechanism on ≤ 3 1/2-in. (88.9-mm) packer bodies, while larger packer sizes (≥ 4-in. or 101.6 mm) use drag blocks. Automatic J-slot sleeves are standard equipment on all packer bodies.
Subsurface Control Valve III (SSC III)
The Subsurface Control Valve III (SSC III) is the only subsurface safety valve in the industry that will support up to a million pounds of drillstring, providing operators with a safe, efficient, and cost-effective means to secure rigs and to evacuate personnel when the threat of a hurricane or typhoon arises.
The SSC III storm valve is a combination ball valve and backoff joint with a unique retrieving head that allows operators to close in a well that is being drilled without having to pull the workstring. The valve reduces the time and risks when repairing blowout preventers or leaving all pipes standing in the derrick during a storm.
The SSC III valve (3.5-in. ID and 8.5-in. OD) supports a working pressure of up to 8,000 psi (55 158 kPa) with a working tensile rating of 1,000,000 lbs (453 592 kg). Published charts for hang-off weight and pressure test limitation show a tensile rating of 1,204,766 lbs (546 473 kg) with a maximum hanging weight of 1,000,000 lbs when used with the high-strength RTTS™ packer (13-3/8-in. casing) at 1,000 psi (6895 kPa). The SSC III valve features a unique overshot for non-rotating detachment, employing a right-hand quarter-turn torque to set and detach, then to reattach positively.
The SSC III valve reduces rig costs and personnel exposure time—two factors that become vital during hurricane season. Halliburton‘s subsurface control valves have proven reliability, successfully controlling more than three-quarters of the Gulf of Mexico wells during the 2005 hurricane season.
