Friction reduction system aids optimized bent-motor BHA to drill Vietnam’s longest basement section

Operator drilled section to TD and connected all targets despite extreme difficulties encountered in this complex wellbore By Son Bui, Thang Long Joint Operating Company; Ngo Huu Hai, Petrovietnam Exploration Production Corp; Nam Nguyen, Geoff Blackwell and Jake Tretheway, National Oilwell Varco Thang Long Joint Operating Company (TLJOC) was operating a well in the Cuu Long Basin offshore Southern Vietnam and needed to more effectively drill through a difficult section. Granitic basement drilling, where the formation is very hard (35 to 40 kpsi UCS), presented major challenges, as PDC cutters could not drill through the formation, very high levels of vibration were encountered, and rate of penetration (ROP) was limited. Despite the inherent risk of drilling such a well, TLJOC ...

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, ...

Land market steadies after late 2018 dip

High-spec rig market recovering well, with both rig demand and dayrates expected to remain healthy for remainder of 2019, although contractors may delay rig upgrades as cash flows tighten By Linda Hsieh, Editor & Publisher When oil prices took a sudden and surprising dip in late 2018 after what had been a relatively strong and stable year, it caught the industry off guard. It also led to a bit of panic in the industry, with worries that the price slump would lead to another market downturn in 2019. “Fortunately, it did not. It rebounded,” Chris Menefee, Senior Vice President of Business Development for Independence Contract Drilling (ICD), said. “But it still caused some uncertainty… and it couldn’t have come at ...

Ben Ramduny, Seadrill: Drilling contractors seek support from industry suppliers for cost-effective, retrofittable security solutions

By Linda Hsieh, Editor & Publisher From bounty hunter to genetic engineer to salesman to tour guide, Ben Ramduny went through several childhood dreams, ambitions and life phases before finding his passion in information and cybersecurity. His affinity for computers began when he was a young child growing up in the English town of Crewe, playing with early-model home computers like Spectrum and Amstrad in the 1980s. This interest in computers continued throughout his childhood so that, by the time he was in his 20s, he had gained enough computer knowledge on his own to get a job on the IT help desk of Fujitsu Services. “This was 1999, when not everybody had a computer,” he recalled. Working for Fujitsu ...

Rig count rising: Bakken drillers appear positioned for fresh growth

Bakken rig count hits 60 for first time since 2015 just as production reaches record high By Julie Francis, Wood Mackenzie The state of North Dakota reached a milestone in the last week of March 2019 – the rig count rose to 60 for the first time since December 2015. The achievement comes on the back of another important breakthrough from January – Bakken production hit a record-high 1.376 mmboe/d. While 60 is the highest rig count for the state in more than three years, it’s still eclipsed by the levels reached before the oil price crash of late 2014. The downturn forced Lower 48 operators to improve their working practices: They hired fewer rigs and completed fewer wells. But ...

Rotary steerable technology helps operators to beat AFE timelines in Granite Wash, Midland Basin wells

Point-the-bit RSS proves value in drilling of complicated wellbore trajectories in harsh environments, saves 8 days of drilling in one well’s lateral section By John Evans and Brian Jansky, Gyrodata One of the most significant drilling advancements in the petroleum industry in recent years has been the development of rotary steerable systems (RSS), which have proven valuable for directional and horizontal drilling. The first commercial use of Gyrodata’s RSS tool was in 1993. At that time, it was called an automated guidance system. These systems use specialized downhole technologies to replace conventional directional tools, such as mud motors. RSS technology allows guidance of the well trajectory while the drill string continuously rotates. This eliminates the need for an operator to ...

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 ...

Overcoming learning curve leads to successful deployment of dissolvable plugs in Chinese shales

Understanding reasons why dissolvable frac plugs might not dissolve helps suppliers to address operational challenges, provide better operator experiences By Jack Wang, Vertechs Oil & Gas Technology Unconventional oil and gas development is on fast track. This is rapidly reshaping the technologies we know and continues to encourage performance, competition and innovation. But a learning curve must be overcome before a new technology can become an industry standard. This article will provide an introductory overview of dissolvable downhole technologies, particularly the challenges and failures that were encountered when they were introduced to the Chinese market in early 2016. Three years ago, China expanded the scale of its shale gas development. To maximize production, longer laterals were drilled. However, this came ...
