"FIRE IN THE HOLE" - INDUCED SECONDARY PERMEABILITY OF A LOW K FORMATION: WHAT A BLAST!
Luhrs, B. | RemTEC Summit, February 26-28, 2019, Denver, Colorado. 32 slides, 2019.

Wells at the Austin Chalk formation were taking ~6-9 months to recharge back to static water level after installation. In response to a shortened project schedule due to impending redevelopment, alternative and innovative options were explored to expedite remedial actions and enhance the success of treatment injections. Two approaches were used: hydro fracking and 198 focused explosive charges. Lessons learned range from types and amounts of charges, grid spacing, appropriate density of water-level measurements, changes to the vadose zone, and impacts to formation permeability. https://www.remtecsummit.com/ext/resources/Static-Pages/presentations/Bob-Luhrs.pdf
