Abstract

Unconventional reservoirs
are just that – unconventional. Extrapolation of techniques that have
been used for decades in conventional reservoirs to unconventional
reservoirs is dangerous and can prevent further development by providing
poor results and turning funding away to “safer” areas. In order to
avoid such misapplications, unconventional reservoirs call for
unconventional thought processes. In no place is this more evident than
in the area of hydraulic fracturing, where an entirely different mindset
has to be developed, not just for unconventional reservoirs in general,
but specifically for each individual type of unconventional reservoir
including shale gas, tight gas, and low permeability oil.
These changing approaches affect almost every aspect of
unconventional treatment design from fracturing materials to reservoir
management. Increased use of “slickwater” and other minimally-loaded
fracturing fluids can be directly related to the desire to minimize
damage in these tight, low permeability
reservoirs. However, these types of fluids have different
proppant transport mechanisms that must be considered. From a mechanical
aspect, fracture growth in unconventional reservoirs can be extremely
complex, beyond our current capabilities to completely predict, and
direct diagnostics coupled with mineback and laboratory experiments are
helping to improve the understanding of what causes these intricate
patterns. Even from a reservoir management standpoint, hydraulic
fracturing has become more of a tool rather than just an event.
Diagnostic injection tests can provide information on reservoir
characteristics; and reserve recoveries can be enhanced through
practices such as improved well spacing and reorientation of fracturing
treatments.
This presentation reviews these changing perspectives and
design considerations. The main “take-away” from this lecture is that
unconventional reservoirs have requirements very different and distinct
from conventional reservoirs and that we can improve our designs by
considering these unique requirements and “thinking unconventionally”.
