					Unconventional Reservoirs Require Unconventional Solutions – Some Applications in Granite
Wash and Shale Reservoirs.

Charles H. Smith, Halliburton

Horizontal drilling into these reservoirs followed by intensive perforating and fracture treatment techniques
have been the accepted standard for producing these wells. The general thought process was that the
closer these perforations could be placed and treated, the greater the production rates.

Data published recently also show the plastic nature of these unconventional reservoirs. In one study, the
rock was placed in three-dimensional stress conditions and then perforated. Within 48 hours, the
perforation tunnel had closed off, eliminating the ability of fluids to migrate to the well, which could also be
a source of decreased production. A technique was required to find intervals of the well that could support
open perforations to maintain contact of the formation to the well.

Magnetic Resonance Imaging Logs and dipole sonic logs were added to the logging program to establish
additional parameters that could be used for reservoir description. The Bray-Smith equation, which has
been used for several years to describe permeability, was used as a base to define relative permeability
in these reservoirs. The Dipole was processed to define ability of the reservoir to accept fracture
treatment and the ability to maintain that treatment. This paper presents the results of these applications
in several unconventional reservoirs.

Charles H. Smith, Halliburton
Charles H. (Charlie) Smith has spent 30 years in the oil and gas industry.
He received a BS in Mining Engineering from the University of
Arizona and immediately started work for Schlumberger as a field
engineer. He worked there 20 years as field engineer, sales engineer,
district manager, regional manager and senior sales associate. In
1999, he left Schlumberger and has worked for Halliburton since that
time. He currently works as a Senior Account Leader in Oklahoma
City and spends most of his time focused on Magnetic Resonance
applications for the oil and gas business.
