The ELSA-HP has been developed to service the high pressure horizontal tree completion and intervention market.  With systems designed and qualified up to 15,000 psi, 250 degF and 10,000 ft water depth, this landing string assembly provides our clients the safety and reliability required to develop fields with these challenging conditions.

Expro used the highly successful and field proven ESLA-HD design as the basis for the development of the ELSA-HP product line.  With an established excellent track record, proven reliability and designed for operations in deep water environment these systems were ideally suited for the high pressure market, of which the majority is located in the deeper waters of the Gulf of Mexico.

In addition to the higher pressure rating of the systems, a passive latch orientation mechanism is incorporated, negating the need to rotate the string upon landing string reconnect.

As more dynamic positioned vessels are being used for deep water completion operations, the likelihood of shear ram activation during completions has increased.  A mechanical latch retrieval tool has been developed for this event, allowing the latch assembly to be retrieved, enabling the system to be repaired, reinstalled and operations to be continued.

Both the valves in the subsea test tree have also been tested under hyperbaric conditions ensuring valve fail-safe closure with spring force only, while being exposed to maximum external pressures guaranteeing our clients the safety features required to complete wells in these harsh environments.
