P&A cost management: Some international experience and practical application in Vietnam
Abstract
The article analyses the factors affecting P&A (Plug and Abandonment) cost, which makes up a great proportion in the decommissioning cost structure. The authors review the P&A steps in theory, regulations, and practice. At the same time, factors affecting P&A decisions and P&A planning are studied in terms of work and cost as well. On that basis, the article presents some existing P&A cost estimation methods and their possible applications in Vietnam. Elements that may help optimise P&A budget in particular and decommissioning budget in general are also reviewed and presented.
