The dynamic realm of offshore drilling and completion continually sees the development of innovative technologies aimed at enhancing safety, efficiency, and cost-effectiveness. This edition highlights three papers showcasing transformative potential within the industry.
The first paper explores the use of along-string measurements and high-speed telemetry to mitigate geohazards and improve risk management in drilling operations. This innovative approach has significantly improved operational efficiency and well placement in offshore environments. By leveraging real-time data and advanced telemetry systems, operators can make informed decisions that enhance safety and optimize drilling operations. Several case studies showcase the successful implementation and potential of this technology to revolutionize the industry.
The second paper introduces a pioneering digital shaker surveillance system using computer-vision technology on a deepwater rig. In an experimental trial, a computer-vision system monitored and measured drilled cuttings in real time. The system used an optical sensor and image-analysis software to quantify and qualify cuttings during drilling operations. Data collected revealed a strong correlation between cuttings load and drilling-parameter perturbations, improving assessments of hole cleaning and wellbore stability. The system aims to boost drilling efficiency, optimize penetration rates, and prevent packoff events by autonomously characterizing drilled cuttings.
The third paper discusses the evolution of riserless mechanical subsea intervention in the deepwater Gulf of Mexico through a 22-well, multiyear campaign. Advancements in deepwater subsea well-intervention technology have enabled operators to perform more-sophisticated mechanical interventions (with wireline and slickline) without the need for a riser, significantly reducing costs and operational complexity. Case studies demonstrate the benefits, challenges, and prospects of riserless well intervention.
