The complete paper presents a methodology designed for optimally matching drill bits, mud motors, and bottomhole-assembly components for reduced failure risks and improved drilling performance.

This paper explores the nature of the vibrational dysfunction known as BHA chatter. A field-proven frequency-domain model illustrates the cause of the dysfunction, its rotary-speed dependence, and mitigation methods and results.

The agreement will introduce rod couplings coated with nanolaminate technology with the goal of improving equipment reliability.

Achieving and sustaining performance drilling’s intended benefits—improved drilling efficiency with minimal downhole tool failures and the associated reductions in project cycle time and operational costs—requires new protocols in drilling-system analysis.

The practice of burning off natural gas is relatively rare in Colorado, but tough rules on flaring and venting may help the state meet greenhouse gas reduction goals.

Smartphone apps can help workers manage their own personal health information.

Canada’s methane emissions from the oil and gas sector in Alberta and Saskatchewan are almost twice as high as had been previously reported, according to a new study by federal government scientists.

Despite having strong wind resources and promising record-breaking capacity factors, most sites globally are unsuitable for bottom-fixed units. Floating wind will provide part of the solution for countries seeking to decarbonize their electricity.

Wind energy sources located offshore present challenges in transporting large amounts of energy. Energy transport through hydrogen molecules may be a solution. The PosHYdon project is intended to build experience with offshore H2 production and test power-to-gas technologies and integrated systems.

This paper’s intent is to provide a basic understanding of offshore renewable energy, including descriptions of wind and marine-hydrokinetic devices, with a focus on the physical and technical issues.
