RBN Energy: Which Bakken Operators Have the Biggest Inventories Of Top-Tier Drilling Sites? Link here. Archived.
Three-quarters of the Bakken's top-tier well sites may have already been drilled and the basin’s remaining inventory may be less than stellar, but a new AI-based analysis suggests that the quality of the locations held by each of the shale play’s top 10 producers varies widely. For a few, there are still plenty of spots that make economic sense to drill and complete, but activity may slow to a crawl for others unless crude oil prices rebound — and in a big way. In today’s RBN blog, we continue our look at Novi Labs’ intense examination of the U.S.’s second-largest onshore production area.
This is the second blog in this miniseries. In Part 1, we said that while Bakken crude oil production is humming along at a steady 1.2 MMb/d, about 75% of the shale play’s top-quartile locations have already been drilled and only 6,100 well sites — about six years of inventory at the current drilling pace — could generate a good return at the range of commodity prices we’ve seen the past couple of years. We also explained Novi’s data-based, machine-learning-enhanced approach to analyzing the many layers (aka benches) in the Bakken (and other shale plays) to determine not only how much crude remains underground but how much is likely to be produced under various price scenarios.
Put simply, machine learning crunches a wide range of geologic, operational and spatial data collected from thousands of drilled wells to recognize patterns and identify the primary drivers of well performance. It then enables operators to assess how changing variables (like drilling in a higher-pressure area, tightening well spacing or increasing proppant intensity) would affect production outcomes in wells yet to be drilled. And it gives operators guidance on how best to lay out, space and sequence the development of the benches.
More important for our purposes, this approach also reveals the relative quality of the rock in various parts of a shale basin and how much of the remaining resource is likely to be developed at various crude oil price points. Regarding rock quality in the Bakken, the basin’s existing and potential wells are separated into four quartiles or tiers, with Tier 1 wells being the juiciest and (generally speaking) the most economic and Tier 4 wells having the lowest quality and being economic only if oil prices are very high. Finally, we noted there are two common ways to assess whether it makes sense to drill and complete a well: using a straight two-year breakeven or using a more conservative NPV25 breakeven, with NPV referring to net present value. (See Part 1 for details.)
Last time, we took a big-picture look at the Bakken’s remaining inventory of drilling locations. In today’s blog, we shift to a company-by-company analysis that reveals significant differences in the quality of their yet-to-be-drilled sites.
