Deep, applied knowledge of drilling and completion cost structures and production costs, including major and minor spend categories, engineering versus procurement trade-offs, completion strategies, well type and vintage economics, and failure modes and costs, sufficient to interrogate cost data and spot when a number does not align with industry practice or engineering logic. Delivering quarterly Executive Briefings that diagnose cost drivers, benchmark performance against market peers, and turn findings into actionable insights on specific operational questions (for example, engineering versus procurement cost drivers, well type and vintage stratification, vendor performance mapping, and failure modes and associated costs).
