In the entire life cycle of the exploratory drilling campaigns, the technical and financial documents, Geotechnical Order (GTO), and Authorization for Expenditure (AFE) have a role in stakeholder and portfolio management, including investment opportunities. Executing GTO and AFE documents has challenges in committing huge capital outlays contributing to operational costs. Lack of operational awareness, manual documents, and disparate databases, including discrete accounting and reporting systems, make the upstream businesses challenging with shattered budgets. Other issues are intricate supply chains, disengaged standards, rigid government regulations, political uncertainties, and inconsistent fiscal systems. The authors investigate the existing inconsistent guidelines of exploratory drilling campaigns, information barriers, uncertainties, and bottlenecks of implementing Joint Ventures (JV) under the Production Sharing Contract (PSC) with stakeholders. We design Information System (IS) articulated techno-economic decision tree template and its associated multidimensional attribute journey modelling to integrate the technical and financial documents with exploration business knowledge. High-speed computing (HPC), Business Information Systems (BIS) and Cloud- and fog-computing services can be added tools for investments in the oil and natural gas industry. Customer Relations Management and Enterprise Resources Planning extranets can collaborate with the techno-economic framework and template. In addition, a multidimensional repository system with fine-grained data structures can attract the Exploration and Production (E & P) portfolios. The techno-economic facts-guided decision-tree template can digitally customize the exploratory drilling campaigns and make realistic technical and financial decisions. The methodology can deliver timely, valuable, and accurate information to explorers, investors and managers involved in the E & P projects, including two-way communication and business-to-business interactions. The decision-tree template can be reusable and interoperable in multiple domains of the E & P industry. The techno-economic decision tree template is usable in various oil and gas finds, easing stakeholder and portfolio management, including flexible GTO and AFE document structures.
