Xodus reviews decommissioning options in Tunisia
Xodus Group has performed a decommissioning and abandonment study for wells, surface, and subsea facilities in Tunisia for local company Thyna Petroleum Services.
The six-week study involved developing a cost estimate for developing, among others, one offshore field and two onshore storage/processing sites.
Xodus undertook a risk and opportunities assessment and reviewed regulatory and environmental aspects of the facility and infrastructure removal program.
It also put together an asset register, an abandonment strategy and site remediation in line with current industry best practice and in-country regulations.
The study allows the joint venture partners to define their decommissioning cost liabilities and a timeline for the project. Thyna’s portfolio in Tunisia includes the offshore Cercina field, which has eight producing wells.
Nizar Taga, finance manager for TPS, said: “The study achieved the objectives it was set out and the Xodus’ project team was successful in applying its deep understanding of decommissioning to inform the JV partners the key drivers that can materially impact the overall decommissioning cost and schedule.
“Xodus highlighted the risks and mitigation strategies that, if implemented, would reduce several of the inherent uncertainties associated with decommissioning a multi-asset field.”
Last year, Xodus undertook a similar program for a large offshore complex in Tunisia.
It also performed a study that compared the country’s decommissioning procedures to those in the North Sea, analyzing the regulatory regimes and execution practices.
