Abstract
In the latter part
of 1989, a new system for
energy
and power production was first tested in Texas.
A hybrid
geothermal
power plant was built, tested, and run for 121 days
producing electrical power that was sold to HP&L. While a technological success,
timing was poor for commercialization. Oil and gas were inexpensive. No
incentives existed for renewable
energy
production in the state, no one was
concerned about not having sufficient electrical
energy
for the economy, and
California and other parts of the country had yet to experience electrical power
shortages. Those times have changed.
The deep Permian
Basin is one of 5 regions within the state that has the potential for holding
vast amounts of renewable heat
energy
. Temperatures well in excess of 212F are
present in deep wells. This hot water, generally considered a liability when
encountered in the O&G drilling process, holds the key for a restoration of the
Texas oil and gas industry and its infrastructure for decades to come. Existing
technology can capture this heat and generate electrical power. Many 1,000's
Megawatts are probable from this heat
energy
. Conventional
geothermal
energy
companies have yet to target deep sedimentary basins due to a lack of
knowledge…knowledge of the available resource…knowledge of the subsurface
geological architecture…and knowledge of the data resources developed over many
decades of oil and gas production. The existing O&G industry is presently poised
to take advantage of this
energy
resource and begin developing heat
energy
concurrently with oil and gas production efforts. This presentation discusses
the available heat
energy
and its future development.
