1)Integrated Services Drilling Contracts in Mature Fields – Multi-Dimensional Design Framework
This study synthesizes global ISDC and collaborative contracting experience in mature fields, showing that outcome based integrated models can cut well delivery times and unit costs by ≥10 % while stabilizing well quality when designed correctly. It develops a four dimensional framework (operational continuity, workforce architecture, commercial incentives and data driven practices) and demonstrates, from Oman to the Gulf of Mexico and Asia, that the best results come from multi year portfolios, blended teams, balanced KPI scorecards and robust digital infrastructures.
