In the words of the authors of paper SPE 202460, one of three outstanding SPE conference papers selected by reviewer Gopi Nalla of DeGolyer and MacNaughton for this month’s feature, “As geological and completion complexity of oil and gas fields increases, building a fully representative predictive reservoir model can be arduous to almost impossible.” However, as we see in these papers, new tools and techniques are being developed to match the ability of engineers to meet the challenges posed by assets such as shale reservoirs and maturing fields.

The authors of paper SPE 200466 developed a novel method in which the results of assisted history matching are applied to well-spacing optimization in a shale development, using information extracted from uncertainty and the interpolated maximum net present value. Applied to a real shale well, it is determined by the authors to be reliable enough to apply to other wells.

Paper SPE 202460 exemplifies the accelerating development and popularity of artificial intelligence (AI) in industry applications as its authors outline what they call a top-down approach that uses AI and artificial neural networks to obtain good matching results for a geologically complex offshore Malaysian field.

Finally, the authors of paper SPE 199149 describe a work flow that uses a coupled hydraulic fracturing, geomechanics, and reservoir simulator to identify what they term rate-transient-analysis “motifs,” characteristics that aid in iteration and history matching of unconventional well models.

Thanks once again to all of our JPT reviewers and readers, who make certain that our members, and our industry, remain equipped to adapt to challenging conditions both below and above ground.
