High-durability PDC bit designed for demanding applications

Ulterra Drilling Technologies has introduced its XP line of extreme-performance PDC bits. These bits are designed to provide improved results in the toughest drilling applications, including hard rock, transition zones and highly interbedded lithologies. The XP bit series is based on a bit body engineered to ensure structural integrity under extreme drilling conditions. This level of design allows the bit to withstand more demanding drilling parameters, including greater weight-on-bit (WOB), without sacrificing rate of penetration (ROP). Along with high structural integrity, the bits’ cutter positioning and force balancing are both optimized for reduced tangential overload, to deliver maximum stability under the load of high energy inputs.  XP drill bits are optimized for each application, and paired with the latest application-specific premium ...

Land drillers usher in era of super-spec rigs

Operator demands for repeatability, predictability lead contractors to push ahead on horsepower pressure ratings, hookload and pipe-racing capacity while adding smart, data-analytic functions to control systems By Kelli Ainsworth Robinson, Associate Editor, and Katie Mazerov, Contributing Editor With the industry’s steady, albeit gradual, emergence from the dark days of the downturn, onshore drilling contractors are seeing rig counts rise and dayrates climb. Increasingly, drilling companies are deploying fleets of upgraded rigs to meet operators’ demands to achieve more reservoir contact with longer laterals from bigger pads. Today’s unconventional challenges are a far cry from those of less than a decade ago, when a single shale well might have a 1,000-ft lateral and a few stages. Back then, the talk was all about ...

Automation of directional drilling system with remote supervisory control allows mile-a-day wells to be achieved in Appalachian Basin

Robust digital network enables reliable, real-time data transfer, allows experts to guide geosteering of horizontal wells from off the rig By John Macpherson and Sheldon Knight, Baker Hughes, a GE Company; and John Dewardt, Dewardt & Company Drilling is a highly dynamic process. Interrelated wellsite systems; geologic conditions that can deviate from expectations; operational variables that require continual adjustments, such as weight-on-bit and rotating speed; and the time lag between near-bit sensors in the subsurface and drilling control systems at surface all make automating a drilling operation as challenging as automating space flight. But driven by the promise of improved efficiencies, higher-quality wellbores, economics and safety, the development and adoption of systems automation is accelerating within the industry. The next generation ...

Trelleborg announces new rotary seal for high pressure oil & gas applications

Trelleborg Sealing Solutions has launched a new polytetrafluoroethylene (PTFE) based O-Ring energized single-acting rotary seal, the Turcon Roto Glyd Ring DXL. This seal is designed to meet the demands of high pressure rotary applications within the oil and gas industry. The product provides improved dynamic sealing efficiency and reduced friction by balancing the contact force on the dynamic lip under all service conditions, allowing for superior extrusion resistance and low torque. The seal is available in the company’s proprietary XploR range of NORSOK and API compliant materials. David Brown, Trelleborg Sealing Solutions Global Director – Lead Group Oil & Gas, said, “Trelleborg Sealing Solutions specializes in solving extreme oil and gas challenges, as evidenced by the new Turcon Roto Glyd Ring DXL. Compared to ...
