QUALITY FIRST”
Overpressurized rocks threaten
every offshore drilling rig in Texas.
Dr. William R. Bryant, a marine
geologist, and Dr. L. J. Thompson,
a civil engineer, have been given
$50,000 by the U. S. Geological
Survey to find a solution.
“Overpressurized sediments
occur when the material being de
posited on the ocean floor starts to
consolidate and traps pockets of
water, ”, Thompson said. “As more
sand and sediment is deposited the
pressure on the entrapped water in
creases.
“Now when you drill into one of
these high pressure zones it tries to
blow the mud, drill stem, and ev
erything else out the top of the oil
rig, ” said. “These over pressures are
common to oil companies at great
depths.
“For example, from New Orleans
to Corpus Christi, there are many
such pockets at the 10,000 to 12,000
foot level,” Thompson said. “Re
cently, there was a blowout as shal
low as 3,000 feet.
“Not only that but overpressured
sediments are unstable and subject
to slides, he said. “An understand
ing of this phenomenon needs to be
developed if the overpressured
zones that constitute a hazard to
$25,000 for
alcohol study
granted
The Department of Health, Edu
cation and Welfare has awarded
more than $25,000 to TAMU to
study the effect of alcohol on the
brain.
Dr. W. R. Klemm, project head,
has made some interesting observa
tions on drug rats. He found he
could make them mentally alert
while intoxicated.
By injecting a drug, physostig-
mine, into drunken rats, the cortical
brain waves appear as those of ex
tremely alert rats. Meanwhile, they
physically bump into objects, fall off
the edge of the table, and topple
over.
Klemm hinted that this might be
a first step on the way to developing
an instant “sober-up” drug.
“This work reveals that ethanol
caused motor problems more or less
independently of cortical influ
ence,” Klemm said. The cortex of
the brain is where thinking proces
ses occur.
“To extrapolate this to normal
drinking in the human is not clearly
justified,” he said. “However, such
a relation would indicate that there
is a brief phase of the intoxicated
state when thinking is active.
“The fact that physical intoxica
tion persists when a major part of
the brain is protected by the drug
against alcohol, indicates that al
cohol acts on chemical processes in
the brain in ways which have yet to
be discovered,” he said.
offshore structures are to be lo
cated.
“As a result, we’ve laid out a
four-year program to attack this
problem,” Thompson said. “The
first year a theory needs to be de
veloped that will predict excess
pore pressures for the steady state
process. We’ve got to be able to
predict where they will occur.
“The second year’s task will be to
develop equipment, like a probe,
that will allow us to locate the high
pressure zones,” he said. “Also this
technique might have possibilities
as a mapping tool for shallow sedi
ments. The probe will use the rela
tionship between excess pore pres-
sure with temperature, electrical
resistivity, sonic velocity and poros-
ity.
“The third year will be spent con
structing the probe and the de
monstration of its use through map
ping continental shelf areas where
excess pore pressure might exist,”
Thompson said. “And, the final year
will be spent locating and mapping
the zones of high excess pore pres
sure. ”
The rest of the project staff con
sists of graduate students Phillip
and Robert Chen. Dave Powley,
from AMOCO Oil Company, will
serve as an unpaid consultant on the
project. He has examined over
4,000 well-records studying the
deep problem.
