LA0 Liquid Spring-Actuated Anvil® Plugging System The LA0 liquid spring-actuated Anvil®
plugging system is a pressure cycle-operated device that allows the operator to perform tubing tests or set
hydraulically activated tools and then have full tubing bore ID without wireline or coiled tubing intervention.
The operation of the liquid spring device is carried out by a ratchet mechanism that travels each time pressure is applied for the
predetermined number of cycles. When the predetermined number of pressure cycles has been applied, communication from the tubing to the control line is opened, allowing pressure to activate the Anvil plugging system.
Applications
This tool is ideally suited for deep, highly deviated, or horizontal wells, which would normally require coiled tubing to run plugs for setting hydraulically activated equipment and where it is necessary to apply a number of tubing pressure tests before
activation of hydraulically operated downhole tools.
Features
• Insensitive to changes in annulus pressure
• Control fluid sealed within actuation mechanism
• Solid metal barrier
• Surface indication of successful tool activation
• No waiting on plug to open
• No debris
• Circulating sub
• Mechanical override
• Easily millable
Benefits
• Control fluid in the actuation mechanism is sealed and therefore protected from contamination.
• Unlike nitrogen pre-charged systems, the liquid spring
mechanism eliminates well-specific setup and enhances long-term suspension capability.
• Fluid used to communicate with the hydraulically activated device is carried in with the liquid spring module and therefore remains separate from the tubing fluid at all times, reducing the chance of control line blockages.
• Prior to activating the release mechanism, a solid metal plate is in place to form a downhole barrier that satisfies most operators' plugging policy.
• Sudden pressure drop at the device at activation will be detectable at surface.
• The Anvil plug completely opens at the time of actuation. Controlled metallurgical and dimensional properties help ensure consistent and reliable full opening.
• After activation, the Anvil plug produces no residual debris to potentially cause problems during subsequent operations.
• To allow the tubing to self-fill while running, a circulating sub or fill up sub can be run in conjunction with the Anvil plug.
• In the event the plug does not activate normally, it can be mechanically overridden using a dedicated tool run on wireline or coiled tubing.
• The Anvil plug can also be milled with no rotating parts and only the metal plate to be removed.

LA0 Liquid Spring-Actuated Anvil® Plugging System
LS0 Liquid Spring Actuation Device
The LS0 liquid spring actuation device is a pressure cycle-operated, self-contained tool used to initiate any
hydraulically activated downhole device. The tool allows setting of equipment after the application of a predetermined number of pressure cycles. The operation of the tool is carried out by a ratchet mechanism that travels each time pressure is applied. When the predetermined number of pressure cycles have been applied, communication from the tubing to the control line is opened, allowing pressure to reach the target device.
Applications
The liquid spring actuation device is used when it is necessary to apply a number of tubing pressure tests before activation of hydraulically operated downhole tools.
Features
• No atmospheric chamber or nitrogen-charged chamber to limit time to actuation
• Actuation system is unaffected by changes in pressure in the lower annulus
• Control fluid in the actuation mechanism is sealed and therefore protected from contamination
Benefits
• Total interventionless actuation of hydraulically operated tools.
• Unlike similar actuation devices, the liquid spring is not affected by changes in pressure in the lower annulus.
• Unlike nitrogen pre-charged systems, the liquid spring mechanism eliminates well-specific setup and enhances long term suspension capability.
• Fluid used to communicate with the hydraulically activated device is carried within the liquid spring module and therefore remains separate from the tubing fluid at all times, reducing the chance of control-line blockages.
Mirage® Disappearing Plug The Halliburton Mirage®
disappearing plug is a plugging device designed to run as an integral part of the tubing. The plug can be used to set a hydraulic-set packer or to test the tubing string. It is activated by hydraulic pressure, eliminating the need to use wireline or coiled tubing to run and retrieve the plugging device. Once the plug has been expended, the plug material will dissolve and disintegrate leaving full tubing ID through the plug. A fill sub is run above the plug when tubing autofill is required.
The Mirage plug is available in two versions—the MPB multi-cycle version that allows six pressure cycles before expending and an MPR single-cycle type. The MPR Mirage plugs have no moving parts and use a rupture disk to select the expend pressure.
Applications
• Horizontal and high-angle wells where slickline or CTU intervention after completion is undesirable
• Setting production and isolation packers
• Testing tubing
• Wells where retrievable plug use is undesirable
Features
• Multiple pressure-cycle capability (MPB version)
• Automatic expend after last pressure cycle
• Maximum particle size after expending is less than 1 mm
• Helps reduce well risk; reduces number of slickline or CTU trips in the hole; allows multiple pressure tests before expending
Benefits
• Testing tubing can be accomplished without delay or problems
associated with other plugging methods
• Helps reduce completion costs by eliminating trips to install and retrieve plugging device
• Water used to dissolve plug is carried with the tool
• A diaphragm is run in the top of the tool to keep debris off plug matrix
• Full nonrestrictive ID after expending plug
• Maximum particle size after the plug material has disintegrated is 1 mm, eliminating any well debris
• Can be mechanically activated by wireline as a backup
