Water and drilling discharges: Informed decision-making with DREAM

Dose-related Risk and Effects Assessment Model
The dose-related risk and effects assessment model (DREAM) is a state-of-the-art tool for assessing drilling and produced water discharges.

DNV GL is a licence owner of the DREAM model and practised in applying it to different kinds of projects in both the planning and production phases. This includes running multiple single scenarios to generate reliable semi-stochastic results that can provide customers with a better foundation for decision-making.

Common areas of application include:

  • Planning spud location and measuring drilling discharge impact on sensitive areas:
    Combining the DREAM model results with DNV GL’s risk assessment methodology for vulnerable resources provides operators with an overall risk picture to support informed decision-making. This is helpful in coral and sponge areas, for example.
  • Assessing the general environmental impact of produced water and drilling discharges:
    Applying the built-in environmental impact factor (EIF) tool enables operators to model and measure the scale of environmental impact. This is particularly useful in environmental consequence assessments.
  • Environmental performance evaluation:
    DREAM enables operators to assess the environmental footprint of different discharge regimes; for example, chemical substitutions can be evaluated and ranked. This provides input and documentation for environmental performance and BAT evaluations.
