I resigned my membership from the API RP-19 committee in the mid-1990's because I, as well as most of the other committee members at the time, knew that API Section 1 testing was completely misleading to operators trying to select the perforating system that would maximize their well's production. Now in 2017, It's time to stop wasting billions on developing perforating systems that shoot deep in concrete, API Section 1, and simply create plugged tunnels with heavy metals. Furthermore, it's time to stop misleading well owners into using inferior systems that reduce the NPV of their assets.

CASE HISTORIES AND TECHNICAL PAPERS
Mining the Bakken: Driving Cluster Efficiency Higher Using Particulate Diverters
Paul Weddle, Larry Griffin, and C. Mark Pearson, Liberty Resources
This paper focuses on the evolution of an advanced completion design utilizing solid particulate diverters resulting in a dramatic increase in the number of fracture initiation points as validated with radioactive (RA) tracers. The ultimate goal of this strategy is to increase capital efficiency by placing a dense fracture network more contained within the producing formation. The information contained in the paper should be of great benefit to completion engineers working across a variety of unconventional oil and gas basins.
It is generally proven that larger proppant volumes and more frac stages result in higher oil and gas recoveries, i.e., bigger is better. Practically, the number of stages for a 9,500 ft lateral (typical for the Bakken) is limited to 40 or 50 stages due to operational and cost limits. For advanced completion des...
Extreme Limited Entry Design Improves Distribution Efficiency in Plug-in-Perf Completions: Insights from Fiber-Optic Diagnostics
Kiran Somanchi, James Brewer, and Alan Reynolds, Shell Canada
Limited entry (LE) plug ‘n’ perf (PnP) fracture designs were pioneered in the early 1960s as a cost-effective technique to stimulate multiple pay zones with varying stress regimes (Murphy & Juch, 1960). Conventional completion techniques would involve blanket perforating the entire interval with 4 shots per foot. The technique was revolutionary in that it recommended "limiting" the number of perforations to distribute fracture stimulation fluids into multiple intervals with differing stress regimes. However, diagnostics have shown that LE treatment distribution during the slurry phase is uneven and is highly impacted by several key parameters that may change significantly during treatment. Several papers have been published on the inefficiencies associated with LE design...
