New drilling dynamics tool eliminates need for downhole statistical down sampling

National Oilwell Varco (NOV) has introduced the BlackBox High Frequency drilling dynamics tool, which samples dynamics data at 1500 Hz and load data at 100 Hz and records all high-speed data to its 8 GB memory. Because there is no need for downhole statistical down sampling, all data can be analyzed at surface for the entire run. DC spoke with Steve Berkman, NOV Vice President of North America Dynamic Drilling Solutions, at the 2019 OTC about how the new tool functions and why it’s particularly useful in batch drilling operations. Watch the video for more information.

Electromagnetic signals bolster new look-ahead-while-drilling service

A new look-ahead-while-drilling service called IriSphere is combining directional measurements with advanced automated inversion to detect formation features ahead of the bit, by using multifrequency transmitter and multireceiver directional subs. According to Irlan Amir, Vice President of Marketing and Technology, Drilling and Measurements for Schlumberger, the technology uses electromagnetic signals that are sent from the transmitter into the formation and retrieved by receivers to enable the look-ahead sensitivity and resistivity profiles. In this video with DC from the 2019 OTC, Mr Amir also talks about high-potential applications and benefits for the technology, as well as results achieved in a recent deployment offshore Australia. Watch the video to find out more.

Active Control Device drills deepwater MPD section in Black Sea

AFGlobal recently completed the first MPD section in a Black Sea well for Shell on Noble Drilling’s Noble Globetrotter II drillship. Key to this project is the Active Control Device (ACD), which uses a non-rotating device with an actively pressurized, co-molded element to seal the wellbore annulus and divert returns. This eliminates complex bearing assemblies and high-wear rotary seal components found in traditional rotating control devices (RCDs). In this video at the 2019 OTC in Houston on 6 May, Austin Johnson, Lead Development Engineer with AFGlobal, explains how the system works and its potential benefits. Watch the video for more information.

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 announced 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 the government ...

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 ...

Shell’s DeWitt: In time of transition, industry should seize opportunity to transform

The oil and gas industry sits at a unique point in its history as the world transitions toward more sustainable sources of energy, even as both demand for hydrocarbons and society’s focus on climate change increase. It is now that the industry has the opportunity to re-create itself, said Mike DeWitt, VP of Operated Wells with Shell, at the 2019 SPE/IADC International Drilling Conference in The Hague on 5 March. How to thrive at a time when the traditional energy system is transitioning to more renewable forms of energy is both a great challenge and an opportunity, Mr DeWitt said. He also emphasized that although hydrocarbons will remain a part of the energy mix for the foreseeable future, the industry ...
