Well Cost Estimation: Case Study, Calculation Framework, and Practical Exercise for Offshore and Land Drilling Projects
A well cost estimate turns a defined scope and schedule into priced quantities and services, then adds them up from […]
Advanced Subsea Completions: Wet Tree vs Dry Tree Architecture, Horizontal Christmas Trees, and Subsea Processing Systems
Subsea completions have grown from simple wellheads on the seabed into production systems that can separate, pump and compress at […]
Cost Reduction Strategies: Balancing Savings with Well Integrity
Most drilling cost depends on time, so the largest savings usually come from drilling the same well faster, not from […]
Risers and Flowlines - Flexible vs Rigid Riser Design, Vortex-Induced Vibration, Free Span Analysis, and Offshore Installation
Risers and flowlines connect seabed wells to the host facility. They are pressure containment, structural members loaded by weight, motions […]
Advanced Cost Management Techniques: Achieving Efficiency Through Technical Limit Drilling
Technical limit drilling is a planning and performance method that compares each operation with the best time it could take, […]
FPSO Design and Integration - Topsides Process Layout, Tandem Offloading Operations, Weathervaning Performance, and Hull Inspection
A floating production, storage and offloading (FPSO) unit processes well fluids, stores stabilised crude in its hull and exports it […]
Risk Assessment in Drilling Cost Calculations: Mitigating Cost Overruns with Proactive Strategies
A drilling cost estimate is a forecast of an uncertain quantity. A single number hides how wide the range is […]
Offshore Platform Design - Jacket, TLP, SPAR, and FPSO Concept Selection Based on Water Depth and Field Economics
Choosing an offshore development concept is one of the largest capital decisions in the industry, and once a structure is […]
Non-Productive Time (NPT) and Risk Management: Reducing Project Costs Through Efficiency
Non-productive time (NPT) is only useful as a measure when its reporting convention, activity coding and cost basis are clear. […]
Formation Pressure Evaluation - Pore Pressure Prediction, Overpressure Mechanisms, and Drilling Mud Weight Window Design
Formation pressure evaluation finds where pore fluids are above the normal hydrostatic gradient and estimates that pressure well enough to […]
