Executive Plenary Session: Doing the Right Thing Astral 3, Level 1

“Doing the Right Thing” post-production comes from leaving behind the best legacy for future generations' enjoyment of the environment, users of the seas, governments across the region and citizens of the planet.

That legacy may come from the total or partial removal of surface and subsea structures. The decision of what to remove and what can remain in situ is the result of a complex assessment of environmental impacts, available science, stakeholder input and government priorities. Achieving consensus in decommissioning amongst all stakeholders is a herculean challenge, however, regardless of a unified view, petroleum titleholders must be able to demonstrate that they are ‘Doing the Right Thing’. The government and regulators are responsible parties to deliver the final decision.

Titleholders must educate themselves and others on what “Doing the Right thing” looks like. The Environmental, Social and Governance (ESG) impacts focusing on decommissioning have never been sharper.

Panel Session: Regulatory Playing Field and Role of Government

Global oil and gas companies undertake billions of dollars of petroleum developments to stimulate economic returns for their shareholders and the stakeholders within jurisdictions. Competition exists not only between companies but between governments seeking to attract these investments. For most companies and governmental organisations, their knowledge, procedures and processes are geared to managing the project delivery and asset operation phases. Managing these phases is “Business as Usual” (BAU).

Decommissioning, by definition, occurs at the end of the life cycle of a project. Still, often, decommissioning is managed using BAU processes. Are these processes damaging decommissioning outcomes? The role of government in specific jurisdictions is to ensure the responsible development of natural resources to achieve the goals that its society finds important. The question is: “What does that society considers to be “Doing the Right Thing”?”

The role of government involves putting in place laws and regulations that set clear requirements to enable oil and gas companies to achieve the societal goals of “Doing the Right Thing”. In most jurisdictions, these goals include but are not limited to, responsibly maximising the economic benefits of natural resources, providing local jobs, and limiting the impacts on the environment and local communities. There are natural tensions between these goals. The trade-offs between these goals will set the playing field for industries in a specific jurisdiction.

All the players and stakeholders, but especially the regulators in each jurisdiction, have an important role in managing these tensions and clarifying the desired trade-offs. It is then imperative that the governmental agencies ensure a “whole of government” approach, which articulates the priorities, provides certainty to industry, helps stimulate areas of the economy to support these priorities, and minimises red and green tape.
