Drill bit adapts depth-of-cut control to mitigate stick-slip, enhance ROP

Mitigating vibrations during drilling remains a challenge for many fixed polycrystalline-diamond-compact (PDC) bits, particularly as drillers attempt to drill longer sections in a single bit run. Vibration arising from torsional stick-slip and impact loading in interbedded formation and transition can cause premature damage to a drill bit and other components in the bottomhole assembly (BHA) – ultimately hindering drilling performance....

Automation of surface equipment, dissolvable and shorter plugs push efficiency of fracturing operations

Increasing use of water due to longer laterals and higher stage counts are also driving demand for more cost-effective water management solutions By Kelli Ainsworth, Associate Editor As operators push the number of stages per well to upwards of 75 or even 100 in some plays, they’re also demanding step-changes in the efficiency of hydraulic fracturing technologies and equipment, including associated technologies like water management systems. A significant area of focus has been on reducing plug mill-out time, with more dissolvable technologies coming to the market, as well as the development of shorter plugs with less material to mill through. Technologies are also emerging to automate the surface operations of hydraulic fracturing. While the industry has made significant progress in ...

Selective standardization approach could help industry sidestep market barriers, achieve full automation

Drilling standardization, collaboration and automation have become major buzzwords in the industry in recent years, promising higher reliability, improved safety, increased efficiency and decreased costs. Due to the complexity associated with the automation of rig floor equipment, however, full automation of processes and equipment will not be possible until there is a higher level of collaboration and standardization...
