Mini Massive Frac - A Stimulation Technique for Low Porosity, Low Permeability Zones (SPE 6627)

Summary

In the Ravencliff sandstone of West Virginia, a wells was frac'ed with up to 8 ppg sand, achieving three times the flowrate of typical offset wells with more modest stimulation treatments..

Abstract

Low-porosity, low-permeability zones are being successfully stimulated in the Appalachian Area by a technique termed Mini-Massive Frac. This technique combines several techniques commonly used to increase fracturing efficiency and improve results. These include methods to:

  1. Control fluid loss into hairline fractures.
  2. Control fluid loss into matrix permeability.
  3.  Control fracture height.
  4.  Achieve a deeply penetrating, packed fracture.

Use of the technique has provided productivity increases many times greater than conventional treatments, and these are proving to be sustained increases. This paper describes the mini-massive frac and its application to low-porosity, lowpermeability zones in other areas.
