About This VILT

Using a mix of presentation slides, group exercises and break-out discussions, the course considers the immense task of reducing greenhouse gas (GHG) emissions whilst reducing dependence on hydrocarbons in a limited timeframe and whether the reuse of existing oil & gas networks can help in meeting this challenge. The characteristics of CO₂ and hydrogen and how they affect transport and storage operations are also discussed. Identifying assets and their associated infrastructure for carbon capture storage (CCS) operations in a mature producing gas region is presented, along with a forecast of corresponding abandonment expenditure (ABEX) liability should the redundant networks be considered unfit for reuse. The challenges of transporting hydrogen in existing natural gas pipelines are addressed, along with the pros and cons of producing hydrogen offshore vs. onshore. The options for the underground storage of hydrogen will also be reviewed. The potential to convert abandoned oil & gas wells for geothermal duty is covered in this course.

The fundamental decision of whether to repurpose or to decommission an asset is debated along with the use of simple screening and comparative tools to rank the increasing number of energy transition project opportunities. Finally, the need for measurement, monitoring and verification (MMV) is introduced and the potential conversion of existing wells to monitor future CO₂ injection will be discussed.
