Industry seeks new ways to unlock data, drive optimization

More companies turning to AI-enabled and open-source platforms, both to gain insights from available data and to deploy those insights at scale By Stephen Whitfield, Associate Editor The drilling industry is now inundated with more real-time drilling data than ever before, collected through new and existing downhole and surface sensors. However, many organizations have been frustrated in their efforts to realize wide-scale benefits from this plethora of data in terms of improved performance, cost and time savings, often due to the difficulties in sorting and analyzing that data.  To help organizations accelerate the value generation from data, a host of new technologies and platforms have been developed in recent years focusing on real-time data management, remote operations and artificial intelligence ...

Nabors: Workflows must transform to maximize value of automation

Drillers should be given tools to automate repetitive tasks as rig environment becomes increasingly complicated By Drew Curran and Blakley Farrow, Nabors For decades, advances in the drilling industry have focused primarily on equipment that made manual labor more efficient and safer. But these days, all eyes are focused on automation. There is broad consensus that automation is the linchpin of the oil and gas evolution and that, when you seamlessly connect workflows, you take automation to a new level. Industrywide, companies have significantly improved the way they gather data that originate from workflows, but the reality is most companies have more data than they know what to do with. Consider the rig instrumentation and controls system that impact multiple ...

Expandable liner system mitigates geological challenges, predictably maintains hole size in Ekofisk wells

Expandable system proved to be key enabler for ConocoPhillips as it redeveloped parts of Greater Ekofisk Area Drilling the lower overburden section in specific parts of the Greater Ekofisk Area (GEA) in the Norwegian North Sea can be very troublesome. Wells in these parts may intersect shales with high gas content in the upper section (requiring high mud weight) and unstable zones with massive circulation risk (requiring low mud weight) near the base of the interval.  These challenges have brought forth the need for a contingency drilling liner to “split” the section in two parts. Rather than changing the basic well design, ConocoPhillips fronted the development of an 8 ⅝-in. expandable drilling liner with high collapse resistance for this purpose. This string provides an ...

Drill pipe logging sub uses real-time downhole data to improve liner, lower completion installations

Tool leverages wired drill pipe platform to eliminate guesswork at surface, reduce NPT By Kim Mathisen, Tore Sorheim, Vijay Kumar Keerthivasan and Dustin Young, NOV Completion; Stephen Pink, NOV Wellbore Technologies In the well construction process, after pulling standard instrumented bottomhole assemblies (BHA) to surface, the subsequent liner deployment typically happens without any sort of downhole sensors or diagnostics. The liner is often subjected to the most strenuous conditions during well construction, and an unsuccessful installation can add significant amounts of nonproductive time (NPT) and other costs for operators.  Surface data, torque and drag simulations, as well as previous experience, are commonly used to plan and facilitate liner installations. However, field development campaigns often present challenges that cannot be sufficiently planned for by ...
