Petrobras reduces operating costs, time with new pre-salt subsea deployment technique

摘要

At the end of last year, Petrobras deployed its first wet Christmas tree using cables in the pre-salt area. The main change involved was the use of a subsea equipment support vessel (SESV) to install the equipment rather than a traditional drillship. This result ed in a time saving of approximately 10 days, generating a gain of more than $5 million, according to the operator. The Christmas tree was installed using this technique on Well 7-SPH-2D-SP, which is located on the Sapinhoa field in the pre-salt layer of the Santos Basin, at a depth of 2,130 m.
