This session focuses on the latest developments in drilling applications used during exploration and development of wells. These applications are design specifically to improve well costs and schedules. The overall spectrum of well planning, engineering and design, execution will be covered; along with highlights on technical solutions of key challenges in our current drilling environment. The industry, utilises tool and equipment inspection (QA & QC) as an approach to achieve drilling assurance and reliability. Several examples of initiatives to reduce Non-Productive Time (NPT) through the application of geomechanical studies and the improvement of drilling practices to minimise operational problems related to well bore stability will be covered.
