Measurement While Drilling (MWD) – Patenting and Technology Development Trends

Measurement While Drilling (MWD) – Patenting and Technology Development Trends

Measurement while drilling technology is a critical part of the oilfield drilling operations as it enables the driller to achieve precise well placement by efficient steering the drill bit in planned well path to reach the target in shortest possible time. Real-time formation evaluation measurements transmitted to the surface while drilling helps optimize drilling and improve recoverable reserves. Therefore recent development in MWD technology has been focussed on improving sensor capabilities together with advanced dual-telemetry systems. In this study, we cover technology development trends and stakeholder initiatives in moving away from traditional MWD methods towards a more accurate and high speed data acquisition and transfer technologies.
