As drilling of new oil and gas wells increase to meet energy demands, it is essential to
optimize processes to ensure the health and safety of the crew as well as the protection of …

Hydrocarbon exploration and production involve drilling through rock formations to reach
and access target hydrocarbon reservoirs deep below the ground in the safest and most …

Abstract Analysis of mechanical and thermal-induced wellhead growth and resultant loads is
critical for tubular stress design and failure analysis of offshore platform wells. A particular …

Oilfield economic conditions today continue to emphasize the need to recognize and
respond to drilling dysfunctions quickly to maximize performance and minimize well costs. It …

Stuck pipe and other related drilling hazards are major causes of non-productive time while
drilling. Being able to spot early indications of potential drilling risks manually by analyzing …

Despite the market up-cycle efficient use of CAPEX for upstream well construction projects
remain a key topic for E&Ps. Therefore, non-productive-time and invisible-lost-time (NPT & …

Decision making to optimize the drilling operation is based on a variety of factors, among
them real-time interpretation of drilled lithology. Because logging while drilling (LWD) tools …

Gas kicks occur frequently in deepwater drilling because of the extremely narrow mud-
weight window [minimum 0.01 specific gravity (sg)]. The traditional kick-detection method …

A fundamental component of a real-time drilling analytics system is automatic rig state
detection. High frequency time series data (typically one data point per second) from …

One technique useful in the testing and development of drilling automation system is to use
synthetic data. A good drilling time series simulator can enrich a dataset for testing, and …
