Physics-based, deep learning model improves screen-out predictions

By Stephen Whitfield, Associate Editor Screen-out usually occurs when proppants carried in fracturing fluid create a bridge across the perforations in a fracture or a similar restricted flow area, creating a sudden and significant restriction to fluid flow that causes a rapid rise in pump pressure. This condition can cause significant disruption to a hydraulic fracturing operation, delaying the placement of subsequent stages and wellbore cleanout operations, and ultimately leading to lost production days.  Because of that potential impact, advanced warning of screen-out is critical to improving operational safety and efficiency, according to Dr John Sun, Senior Data Scientist at Noble Energy. Speaking at the 2020 Unconventional Resources Technology Conference (URTeC) in July, Dr Sun discussed how his company has ...

US Forest Service eyes drilling approval for Ruby Mountains

The US Forest Service is considering a proposal to allow oil and gas exploration in Nevada’s Ruby Mountains. The proposal would open more than 50,000 acres to drilling, with caveats that operators could not disturb the surface of the mountain range. The Forest Service’s proposal is detailed in a draft environmental assessment, which was obtained by the Center for Biological Diversity, an environmental group opposed to drilling. If the plan is adopted, drilling companies will be able to place rigs on adjacent BLM property and utilize directional drilling techniques to access any reserves under the mountains. The 75-mile long stretch of land being considered runs down the mountain range’s western slope, right through the middle of the Pine Valley play ...
