Hybrid analytical hierarchy process model for the optimisation of marginal field development in Nigeria.
The slow pace of marginal field development in Nigeria poses a critical challenge to the nation's energy security and economic stability, given the reliance on oil and gas revenues. This stagnation stems from the lack of a systematic decision-making framework to address uncertainties in planning …
