Endeavor Management proposes subsea decommissioning joint industry project

Offshore staff

HOUSTON – Endeavor Management has released a proposal for a joint industry project (JIP) to support global best practice development in subsea decommissioning.

The genesis of this JIP is the work completed for Petrobras by Endeavor Management to research global best practices for subsea decommissioning. This study benchmarked Petrobras and five additional operators. The initial study highlighted the need to perform more evaluation of specific subsea decommissioning topics, which are covered in this JIP.

Companies who join Endeavor’s JIP study will benefit from the study’s focus on these areas:

·         Develop an economic model to predict costs using three basic vessel types (riserless light well intervention; workover vessel with small bore riser; and MODU)

·         Achieve MODU capabilities for subsea well P&A at a lower price

·         Examine resins as a replacement for cements in well P&A

·         Evaluate ways to improve methods and equipment to flush subsea infrastructure during decommissioning

·         Identify industry capabilities to perform cement bond logging beyond the first casing string

·         Evaluate cutting through multiple casing strings and downhole control lines for P&A activities

·         Identify ways to sense conditions in outer annuli of existing subsea wells

·         Improve the design of OEM equipment and subsea systems for more effective P&A in the future

·         Identify ways to measure and deal with well contaminants such as mercury, arsenic, and NORM.
