It is important to realize the
benefits of ongoing R&D efforts during high pricing periods.
Seven years ago, complex reservoirs like the Barnett Shale
unconventional gas play in Texas did not significantly register
on the USGS radar screen, but today it's one of the ten largest
gas plays in the United States. Technologies like horizontal
drilling, 3-D seismic and aggressive reservoir fracturing have
unlocked tight gas reservoirs that were uneconomical and thus
overlooked in the past. Encouraging results have opened up new
ways of thinking that allow industry to better understand
complex geologic environments.
Much of that domestically-focused
R&D will involve universities or geological surveys that provide
key support for the professionals of tomorrow. In many
DOE-supported projects, industry and academia work alongside
each other leveraging their respective strengths to reach
project goals. Beyond the research results themselves, the
involved students will enter industry with greater knowledge of
how to practically apply the concepts they learn. Those entering
the workforce are now expected to contribute from day one, which
requires both book learning and practical knowledge.
It is key to note that, although high energy prices are quoted
in the NYMEX, domestic producers are not guaranteed to share in
this run up. A quoted price in New York does not reflect what
regional price pictures dictate. Rather, a spread |
discount difference increases
with an increase in quoted NYMEX prices. For example, producers
in the northwest have experienced over a $22 per barrel
differential before a further discounted adjustment for crude
gravity and transportation. In the Appalachian region, $6 quoted
gas can net some producers in the range of $3 per mcf delivered.
On the other side of the
equation, direct costs have risen. Many operations are energy
intensive so producers who must use electricity, natural gas or
diesel for their enhanced production have seen expenditures
double, triple and even quadruple. The price of tubular services
including iron to drill, case and provide production tubing for
well completions has risen to historical heights. The charge for
other services is also rising with demand for production.
As the economics change, so do
the targets for reserve replacement. While the higher prices do
not drop directly to the bottom line, regional price pictures
vary widely when considering purchaser's midstream,
transportation issues and even international alternatives.
The U.S. has been a key
beneficiary of past R&D investment. Clearly, an investment in
technology by domestic industry in cooperation with state and
national governments will play a crucial role in the ability to
harvest these more difficult reserves in the future. |
