Intelligent Completions allow for more efficient production of oil and gas by combining real-time monitoring with remote flow control capabilities. Data acquired during production permits the customer to alter the flow characteristics of the well without intervention.

To meet the needs of demanding intelligent well applications, WellRx has developed high performance “MATI” Series Intelligent Completion Packers with instrumentation and control line feedthroughs.

Features

• Eight Feedthrough Ports for instrumentation and control line feedthroughs like P/T monitoring, Chemical Injection Lines, Variable Sliding Sleeve lines etc.
• No mandrel movement in the packer allowing stacked completions.
• Shift to release and Cut to release feature eliminates premature unsetting of the packer.
• Single Trip System saves Rig time.

Application

• Intelligent well completions in which the packer is set after the well is flanged up, and multiple ports are needed for pressure/temperature monitoring, chemical injection, gas venting and hydraulic line access.
• Zonal Isolation.
• Deviated and Horizontal well Completions.
• With a large ID primary mandrel, up to eight control line feedthroughs and designed for ISO 14310 V0 standards, it is an ideal single string intelligent completion packer even for Deepwater and Subsea applications.

WellRx “PLUTA” Series ESP Completion Packers

The WellRx “PLUTA” series is a dual-string, hydraulic-set, double-grip retrievable, ESP production packer. The PLUTA is an ideal submersible pump packer, and is also available with additional bores for ESP cable, chemical-injection lines, control lines, and well-monitoring devices.

The PLUTA has a sure release sequential upper-slip releasing system that is designed to release each slip individually to reduce the pull required to release the packer. The angles on the slips, cone, and upper-slip body results in release forces that allow the penetration of the slips to be released smoothly from the casing.

Features:

• Sure release upper-slip releasing system.
• Tension force to release packer is easily adjusted before running
• All components locked to prevent preset
• Release shear pins not affected by differential pressures
• Short and compact, ideal for doglegs and deviated wells
• Setting cylinder below elements eliminates all of the critical O-rings after setting
• Straight-pull release
• Can be pressure-tested on location
• Multiple bores available
• No hydraulic hold-down buttons

Application:

• Submersible Pump Installations.
• High-volume instrumented applications.
• Deviated and horizontal wells.
• Monitoring, gas venting, chemical injection and hydraulic line access.
• Multiple zonal isolation.

WellRx “AVAYO” Series Dual/Multistring Packer

The WellRx “AVAYO” Series is a dual-string, hydraulic-set, double-grip retrievable production packer. The WellRx AVAYO Series is a dual-string hydraulic set packer is an ideal solution where production can be demanding from both strings, and is also available with additional bores for ESP cable, chemical-injection lines, control lines, and well-monitoring devices. The WellRx AVAYO Series has a sure release sequential upper-slip releasing system that is designed to release each slip individually to reduce the pull required to release the packer. The angles on the slips, cone, and upper-slip body results in release forces that allow the penetration of the slips to be released smoothly from the casing.

Features:

• Sure release upper-slip releasing system.
• Tension force to release packer is easily adjusted before running
• All components locked to prevent preset
• Release shear pins not affected by differential pressures
• Short and compact, ideal for doglegs and deviated wells
• Setting cylinder below elements eliminates all of the critical O-rings after setting
• Straight-pull release
• Can be pressure-tested on location
• Multiple bores available
• No hydraulic hold-down buttons

Application:

• High-volume instrumented applications.
• Deviated and horizontal wells.
• Monitoring, gas venting, chemical injection and hydraulic line access.
• Multiple zonal isolation.

WellRx “PARAM” Series HPHT Packers

The WellRx “PARAM” Series HPHT Packers come in two variations: Retrievable (PARAM-R) and Permanent (PARAM-P).

PARAM-R HPHT Packer combine the pressure and temperature ratings and reliability of a permanent packer with the convenience of a retrievable packer. It is designed using unique design features that result in a retrievable packer suitable for high differential pressure and high temperature applications. The Slip design offers near 360° casing contact which reduces slip-to casing stress and minimizes internal casing damage. Once this packer is run and set, it is released by cutting the mandrel. When the mandrel is properly and completely cut, the packer will release and all of the packer components along with the tailpipe can be retrieved from the well.

Features:

• The slip-element-slip configuration enables the packer to withstand pressures up to 15,000 psi and temperatures up to 450°F, and to achieve a reliable seal by locking the element in place under variable loads and pressure cycling.
• The slip design offers near 360° casing contact, which reduces slip-to casing stress and minimizes internal casing damage.
• The simple three-piece element design enhances tool reliability by incorporating a fold-backup system to provide extrusion protection.
• No mandrel movement allows for stacked applications.
• The option to set the packer hydraulically or hydrostatically enhances tool versatility.
• Large ID permits its use in mono-bore completions.
• Cut-to-release technology enables removal, even after the packer has been placed under extreme loads.
• An anti-reset mechanism prevents the slip or element from resetting during retrieval.
• Rotationally locked to facilitate milling, if necessary.
• Interlock available.

Application:

• HPHT and Subsea Completions.
• Hot, corrosive, deep, deviated, production or test completions.
• Wells where minimum casing deformation or damage is desired.
• Single-trip completions.
• Multi packer installations.
• Liner top isolation / mono bore completions.

WellRx “TAAP” Series Thermal Packers

The WellRx “TAAP” Series Thermal Packers is a reliable, high-pressure retrievable packer designed for high-temperature injection and production wells in thermal operations. The packers has been designed with rotationally locked components that facilitate milling operations when normal retrieval is impossible. The array system (high-pressure thermal packing element) provides a superior seal that enables the packer to packoff easily and resist swabbing. Packer is fitted with premium packing and sealing elements that are tailored to withstand elevated temperatures, up to 650°F (~343°C).

Features:

• The field-proven design with the slips below the element prevents the buildup of debris improving retrieval reliability.
• High Pressure Thermal Packing Element System.
• Available in many materials tailored for hostile well environments
• The components are locked to enable rotation into liner tops and horizontal sections, saving rig time.
• High Performance in Compact Size.

Application:

• Thermal heavy-oil recovery
• Steam Assisted Gravity Drainage
• Cyclic Steam Stimulation
• Steam flooding
• Geothermal production

WellRx “DRAV” Series Hydraulic Packers (Tubing Mounted)

The WellRx “DRAV” Series Hydraulic Set Packers (Tubing Mounted) range from Low-to-Medium-to-High-Pressure Applications. Drav Series Packers are compact, economical and the short body length makes it ideal for tight radius deviations and horizontal applications. Options are available in Single Grip and Double Grip systems. These Packers have no mandrel movement for setting, thus allowing stacked completions. Straight Pull releases the packer and bypass ports equalize pressure across the packer for ease in retrieval. The shear-release mechanism is isolated from the packer hydraulics to allow low release forces.

Drav series packers are also available in Shift to Release and Cut to Release options to cater to various well applications.

Features:

• No mandrel movement for setting.
• Low Setting Pressure.
• Straight Pull Release, adjustable.
• Short and Compact Design.
