Once the hydrocarbon resources are exhausted or it becomes unviable to extract them further, the E&P project moves to an abandonment phase, and the project is decommissioned. Decommissioning ensures that the E&P installations and infrastructure are removed subsequent to their abandonment and the site is restored in an environmentally sustainable way.
