The decommissioning project, which took place in 2014 in the South Timor Sea, overcame challenges such as unexpected hydrocarbons in a shut-in well, dilapidated tubing, and antique subsea trees, Pellegrini told DecomWorld in an exclusive interview.

AGR, a global engineering and software company, conducted the decommissioning operations for Sinopec Oil and Gas Australia (SOGA), and the issues encountered highlight the importance of detailed planning and accessible data.
