we w

on interest of celebrating the birthof this nation and the freedom

as a result. It occurred to me then and has

lingered with m

any years ago.

In that sense, the Geophysical S

Abstract:

Within the G

ulf of Mexico, m

uch can be learned form the rock

property trends under normal com

paction versus over pressureconditions. O

f particular interest are the AV

O response character-

istics of pay sands within these tw

o environments. W

hile the shaledensity trend is generally higher than the sand density trend undernorm

al compaction conditions, the shale velocity trend “crosses

over” the sand velocity trend from the high side to the low

sideunder norm

al compaction. T

his gives rise to the progressive andpredictable changes in A

VO

class response with depth that is of-

ten anticipated and encountered.

The key ingredient to this predictability is the onset of over

pressured zones. Within an overpressure region the com

pac-tion behavior changes. T

he velocity and density trend with depth

no longer follows the norm

al compaction curve. T

his can causeunexpected A

VO

behavior.

The predictability of these changes based on trend analysis w

illbe com

pared to well log based synthetic m

odels. To demon-

strate this behavior two areas H

igh Island and South T

imbalier

are examined in detail. W

hereas the High Island area has a

more consistent behavior w

ith respect to geopressure, the SouthT

imbalier area is m

ore complicated. In fact four different re-

gions of overpressure behavior can be identified. Within each

of these regions, the shale velocity trend with depth has a very

distinct signature. Using this inform

ation about the local over-pressure environm

ent makes it possible to better predict A

VO

behavior.

Technical Luncheon continued from

for future oil supply on the petroleumindustry and on global society. T

here isno aspect of the energy industry – indeed,the future global econom

y – that will not

be affected by this debate. Long-term plan-

ning by oil and gas company m

anagement

– even continuance within the industry –

will hinge on w

hich side of the debate afirm

’s executive leadership comes dow

n.

Rather than w

eighing in with one side or

the other in the peak oil debate as tow

hether or not an oil supply crisis looms,

this presentation will advance the idea that

a trifecta of crises already looms, creating

a sort of “perfect storm” for the oil indus-

try that could spur the kinds of societalresponses that w

ould mirror a H

ubbert-style future even if the optim

ists on sup-ply are correct. T

he crises center on a lackof com

prehensive data about global oil re-sources, questions about capital availabil-ity, and tim

ing of future development to

match projected dem

and in the coming

decade.

Resolving the uncertainties are critical to

informing a debate that threatens to spin

out of control and thus serve as a politicaltool to bludgeon the oil and gas industryinto early extinction.

There is no greater m

oral imperative than

lifting the billions of the world’s poor out

of the depredations they suffer daily. This

task cannot be accomplished w

ithout low-

cost energy, and oil and gas currently topthe list of low

-cost energy sources that still

have broad public acceptance for expan-sion. T

he industry must resolve the uncer-

tainties on data, capital, and timing, so that

the world has a clear view

of what steps

are needed to help the desperately poorm

ake the transition to whatever energy

future lies ahead.

Abstract:

The relationships betw

een structurally andstratigraphically entrapped oil and gas fields andunderlying m

agnetic basement along the south-

ern margin of the East Texas B

asin and south-ern and eastern flanks of the Sabine U

plift intoLouisiana have been evaluated by integrating ahigh resolution aerom

agnetic survey with a com

-prehensive Low

er Cretaceous subsurface geo-

logic dataset. Well control and field studies con-

firm that structures and faults are instrum

entalin controlling reservoir entrapm

ent. The loca-

tion of fields in this system, along w

ith produc-tion from

a variety of Woodbine, A

ustin Chalk,

and deeper reservoirs, bears a direct relation-ship to deep, w

rench-fault related structures im-

posed on the basement during the O

uachita –M

arathon Orogeny, and since re-activated dur-

ing various episodes of readjustment through-

out the development of the G

ulf of Mexico.

The aerom

agnetic survey entails 25,000 linem

iles of high-resolution aeromagnetic data that

was flow

n with a half by one m

ile flight line grid.Flight altitude w

as 500 feet above ground. Sur-veying utilized G

PS navigation, digital diurnal

deculturing, profile analysis and grid filtering pro-duced im

pressive images of residual structural

and gray shade images highlight

the structure and fault trends at selected “pseudodepth slices”. D

etailed 2-D W

erner and 3-D Euler

depth estimation provide a series of fault picks

at different depths in the section.

The subsurface dataset incorporates over 40 se-

quence stratigraphic picks, net porosity evalua-tions from

over 1000 wells, and core descrip-

tions in East Texas and Western Louisiana. In-

terrelationships between oil and gas production,

aeromagnetic fault and structural patterns, and

isopachs and porosity patterns in high-resolu-tion sequence stratigraphic intervals in the Low

erC

retaceous indicate paleostructural trends thatexerted a strong influence on deposition, reser-voir developm

ent, and hydrocarbon entrapment.

These relationships also suggest that this ap-

proach can be utilized to define exploration leadsin other stratigraphic, structural, and fractureplays, both shallow

er and deeper, where subsur-

face control is sparse or non-existent. This inte-

grated approach is shown to be a good non-

invasive exploration tool for prospecting in ad-vance of leasing and acquiring 3D

seismic.

Abstract:

Elastic impedance is a relatively sim

ple concept, but is some-

what elusive in practice. Just as contrasts in an acoustic im

ped-ance profile, convolved w

ith a wavelet, generate norm

al inci-dence seism

ic data, there should be an “elastic impedance” pro-

file whose contrasts w

ould generate wide-angle reflections. T

heproblem

is that there is no simple closed form

expression forthis quantity. T

here are various ways to approxim

ate it. One is

to integrate Aki and R

ichards’ (1980) approximation for the

Zoeppritz equation (Connolly, 1999, and Sena, 1997). T

he re-sult is useable but unsettling, w

ith angle-dependent (or even depth-

dependent) fractional units. Later work introduced norm

aliza-tions that only partially alleviated the problem

s (Whitcom

be,2002). Subsequent to C

onnelly’s original paper, there have beensim

ilar formulations of a P

S elastic impedance (Landrø, et al,

1999) with the sam

e drawbacks as C

onnelly’s original PP

elas-tic im

pedance, i.e. fractional units. An alternative form

ulationof elastic im

pedance has also been proposed (VerW

est, 1998;and V

erWest et al, 2000) w

hich avoids the complications of the

Connolly form

ulation. In this presentation, a new derivation of

elastic impedance w

ill be shown w

hich yields an even simpler
