Completion & intervention horizontal tree systems

ELSA® HD (high debris)

ELSA® HD (Expro landing string assemblies) was specifically developed to operate in applications with highly aggressive erosive solids and deep water environments, offering exceptional reliability for all horizontal/vertical subsea xmas tree well completion and intervention operations.

The ELSA® HD comprises of a full suite of valve assemblies. The lubricator valve, retainer valve and subsea test tree provides a full range of well intervention, pressure control functions and disconnection capabilities for harsh completion installation, workover or intervention operations.

ELSA® DH (direct hydraulic)

These landing string assembles are designed for direct hydraulic completion and intervention applications and interface with all mono-bore completions when used in conjunction with horizontal and conventional subsea production trees.

The design incorporates control ports enabling tubing hangar running tools and other downhole functions such as subsurface safety valve (SCSSV) and chemical injection sleeves to be controlled monitored. In addition electric cabling can be run through the system to monitor downhole gauges or electric submersible pumps.

ELSA® HP (high pressure)

The ELSA® HP has been developed to service the high pressure horizontal tree completion and intervention market. With systems designed and qualified up to 15,000psi, 250°F and 10,000ft water depth, this landing string assembly provides our clients with the safety and reliability required to develop fields with these challenging conditions. Expro used the highly successful and field proven ELSA® HD design as the basis for the development of the ELSA® HP products.

ELSA® LBEH (large bore electric hydraulic)

These landing string assembles are designed for electro hydraulic completion and intervention applications and interface with all mono-bore completions when used in conjunction with horizontal and conventional subsea production trees.

The design incorporates control ports enabling tubing hangar running tool and other downhole functions such as subsurface safety valve (SCSSV) and chemical injection sleeves to be controlled monitored. In addition electric cabling can be run through the system to monitor downhole gauges or electric submersible pumps.

ELSA® CLV (cutting lubricator valves)

Cutting lubricator valves are used when coiled tubing and/or wireline cutting capability is required in addition to the more traditional requirements for Expro’s lubricator valves.

To facilitate the introduction of through-tubing tools (i.e. coiled tubing and wireline) into production strings longer than those acceptable in a customary derrick installed lubricator assembly and to provide a means of pressure testing the surface equipment and lubricator sections once the wireline tool string has been installed.

ELSA® CLV provides a method of isolating surface equipment from production flow and a pressure tight barrier between the well bore and BOP stack and/or marine riser.

This is supported by complementary control systems for completion and intervention applications.
