Weld County, CO: Perf & Stage Updates

NavPort’s most recent product update included enhancements to Colorado completion data, so this week’s blog will feature a few of the improved fields, specifically perf interval and stage data.  We decided to focus on horizontal Niobrara wells in Weld County, CO and look at changes in perf interval and average feet per stage since 2012.

Filtering down to wells with reported stage data, the average ft/stage has generally decreased from 2012 through 2015, while the average perf interval has increased by 31% over the same time period.

Table 2

Though the average ft/stage for HZ Niobrara wells in Weld County has decreased, viewing individual wells shows a consistent range for the majority of wells at ­~130-250 feet per stage.

CO Stage

Looking at individual wells, it appears that while perf interval has increased on average, wells have consistently fallen into three major ranges: ~3,000-5,000 ft, ~6,000-7,000 ft, and ~8,500-9,500 ft.
