Weatherford introduces intelligent MPD system

Weatherford has launched Victus, an intelligent managed pressure drilling (MPD) system that represents “a step-change in the way we do manage pressure drilling in the industry,” said Etienne Roux, President of Drilling and Evaluation for Weatherford. “It’s not just one widget that we added. It’s an all-encompassing system that will drive efficiency to both operators and drilling contractors in equal measure, and help them to be safer, faster and eliminate waste.” The software system is based on a sophisticated hydraulic model that incorporates all the MPD experience and data that Weatherford has gathered over the past 50 years. The accuracy of this model’s pressure predictions provides for not only early kick detection but also – due to the intelligence of ...

ExxonMobil to proceed with Liza Phase 2 development offshore Guyana

Exxonmobil said today it has funded the Liza Phase 2 development offshore Guyana after it received government and regulatory approvals. Liza Phase 2 will produce up to 220,000 bbl/day and further capitalize on the significant development potential of the Stabroek Block, where ExxonMobil estimates producing more than 750,000 bbl/day by 2025. A total of six drill centers are planned as well as approximately 30 wells, including 15 production, nine water injection and six gas injection wells. Phase 2 startup is expected in mid-2022 and will develop approximately 600 million bbl. Liza Phase 2 is expected to cost $6 billion, including a lease capitalization cost of approximately $1.6 billion, for the Liza Unity floating production, storage and offloading (FPSO) vessel. “With ...

BSEE finalizes improved Blowout Preventer and Well Control Regulations

The US Department of the Interior’s Bureau of Safety and Environmental Enforcement (BSEE) released the final improved Blowout Preventer Systems and Well Control regulations. BSEE’s final Well Control Rule – as the regulation is commonly known – removes unnecessary regulatory burdens to responsible offshore development while maintaining safety and environmental protection. The revised rule reflects the Trump Administration’s focus on smarter regulations that provide regulatory certainty, signal American competitiveness, advance energy security, and sustain economic prosperity while promoting safety. “Today’s final rule puts safety first, both public and environmental safety, in a common sense way,” said US Secretary of the Interior David Bernhardt. “Incorporating the best available science, best practices and technological innovations of the past decade, the rule eliminates unnecessary ...

A rising tide for offshore drillers

Cost cutting, technical innovations and better all-around efficiency position the offshore market for growth, even at lower prices By Katie Mazerov, Contributing Editor After years of market contraction and aggressive cost cutting, the global offshore oil and gas market is showing signs of an upward tick. Analysts are now projecting an increase in spending – even at oil prices considerably lower than those seen in 2014. However, as operators begin ramping up exploration and development campaigns in key basins, especially deepwater, the story looks markedly different from a decade ago. Back then, prices were well over $100/bbl, rig rates were at all-time highs, and shipyards were enjoying an unprecedented construction boom as contractors prepared for operators’ anticipated foray into complex, ...

Landing string buoyancy technology allows deployment of longer, heavier casing while reducing rig time

System uses buoyancy modules to provide uplift force that can offset landing string weight by up to 80% By Chris von Eberstein, Landing String The deepwater drilling industry has always required a variety of new and reliable technologies to push operational limits further as operators seek to explore deeper reservoirs around the world. As deeper waters are explored, casing design is also becoming more complex and casing strings becoming longer and heavier. The demand for deeper wells, combined with more complex well designs, are driving operators to either upgrade equipment or to design around current equipment limitations. While operators recognize the physical limitations of today’s mechanical systems and supporting structures, they are still aggressively pursuing new technologies with the potential ...
