Leveraging Multi-Well Pad Development to Maximize Value in a Deep Tight Gas Condensate Field: A Groundbreaking First in Oman

This paper presents the first full-scale implementation of multi-well pad drilling in Oman’s deep tight gas reservoirs, specifically within Block 10, targeting the Miqrat and Barik formations at depths of 4500–5000 meters. To address the challenges of low permeability, complex completions, and remote desert operations, the team adopted a multi-well pad strategy using S-shaped deviated wells and a walking rig, enabling efficient batch drilling. Each pad hosts three wells spaced 10 meters apart, matured in integrated clusters that streamlined planning and cut the maturation timeline by nearly one-third. Pad locations were optimized using high-resolution geological models to ensure effective reservoir drainage and minimal surface impact, while a 4-string slim well design with directional profiles up to 33° and step-outs of 1400 meters was employed. Completion and testing operations utilized a stack-frac approach with an Integrated Frac Services fleet, achieving significant reductions in mobilization time and enabling green completions with up to 90% GHG emission reduction. Operational synergies included shared BHAs, mud systems, and real-time benchmarking across wells. This project sets a new technical benchmark for tight gas development in Oman, demonstrating how integrated planning, pad optimization, and collaborative execution can deliver scalable, cost-effective solutions in complex onshore environments.
