The document summarizes the history of gold mining in the Black Hills region and the town of Deadwood, South Dakota. It details how George Armstrong Custer's 1874 expedition discovered gold, launching the Black Hills Gold Rush despite the Fort Laramie Treaty guaranteeing the land to the Lakota people. The lawless mining camp of Deadwood boomed but also struggled with fires and declining resources until transitioning to hard rock mining. The Homestake Mine, founded in 1877, became the largest and deepest gold mine in America before closing in 2001, producing almost 40 million ounces of gold total from the Black Hills.

Waterflooding Petroleum Reservoirs in the Newcastle/Muddy Formation, Powder River Basin, Wyoming

What is a Waterflood?
Primary Production = extracting oil from a reservoir without any additives
Production usually declines over time, sometimes rapidly
Loss of reservoir pressure
20-30% recovery
Secondary Production = treating the reservoir to increase production
Injecting water or gas to push oil
Increases reservoir pressure
50% total recovery, or an extra 20-30%
Water injection = injecting water at higher pressure to push the lighter oil towards a producing well
History of Waterfloods
1860s: Oil fields in Pennsylvania had seeping groundwater
Ruin a well, but production jumped just prior
1880: John Carll announced that if water was deliberately introduced it would increase production
Not regulated, potentially hazardous to water supply
1921: Waterflooding legalized and regulated
1950s: Waterflooding became common practice in most oil fields
Patterns
Waterflood Problems
Reservoir already naturally flooded by formation water so nothing left to sweep
High cost depending on type of reservoir
Heterogeneous reservoir
Rock is mixed lithologies*
Intervals of very high and very low permeability*
High clay content*
* Powder River Basin sandstone intervals
Newcastle/Muddy Formation
In Wyoming (PRB), Montana (PRB, WB), North (WB) and South Dakota (BH)
Transitional marine
Series of fluvial and marine sandstone and shale intervals – very heterogeneous
Each sandstone separated by a shale bed
Oil producer
Different sandstone intervals have produced oil
Sandstone intervals are described separately
North Skull Creek Study Area
Why wasn’t the waterflood successful?
High permeability streaks allowed injected water to continue to sweep these zones leaving the rest untouched – Problem in Newcastle Fm
How to Fix it…
Mix polymers with water to plug up high permeability layers
Forces the injected water into untouched zones = more oil
Shrink/Swell Clays
Injected water makes clays swell
Plugs up formation so no more water can be injected
Add potassium hydroxide (KOH) before injection
Changes clay chemistry
Clays become stable
Common in the Newcastle Fm
Need to add KOH prior to injection – not in North Skull Creek
Conclusions
Extensive geological evaluation before starting a waterflood
Heterogeneity in lithology
Porosity, permeability for connectivity
Calculate pore volume to know how much to inject
Add KOH treatment prior to any injection to stabilize clays
Inject polymers to fix permeability
Increase production from 20-30% recovery to 50% recovery

Many computer program packages are available to utilize in geostatistical interpretation. These include VULCAN, PETRA, GEOGRAPHIX, and in the case of this example I will be using SGEMS - a freeware program. Kriging : Derives the best linear estimate of the variable over a given surface. Smoothing properties of interpolation algorithms replace local detail and replace with a good average. Geologists and reservoir engineers / mining conditions require finer scaled details of reservoir heterogeneity – Kriging is the average of numerous realizations, we may want to see these iterations to determine best fit scenarios

Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.

2. Between the U.S. and the Oglala, Miniconjou, and Brule Lakota,
Yanktonai Dakota, and Arapaho people
Signed at Fort Laramie April 29, 1868
Guaranteed Black Hills to the Lakota as well as hunting rights in the
area – Powder River Country was off limits to whites
Ended Red Cloud’s War over Powder River Country and Bozeman Trail
- ~300 dead
3.
4. People were living in the Deadwood area by the early 1870s
disputing the treaty
1874: George Armstrong Custer led an expedition out of Ft.
Lincoln into the Black Hills
5. Custer reported gold at French Creek (near Custer, SD)
All small quantities until November, 1875 – found gravels
with larger amounts in Whitewood and Deadwood Creeks
Deadwood turned from a few illegals to a camp of 5,000
people
By 1876, a wagon train was bringing people and supplies
1877 - the Black Hills were seized
French Creek
6. Several earlier reports of gold, but
nothing official
Last Testament of Ezra Kind found
in 1887 documented his trip in 1833
where they “got all of the gold we
could carry” – he was killed by
Indians shortly after
1860s, Father De Smet reported
seeing Sioux carrying gold they said
came from the Black Hills – he did
not pursue further
More rumors of gold existed
throughout the region from the early
1800s on
7. The discovery quickly turned into a full Gold Rush
Claims expanded from French Creek up into the rest of the
Black Hills
Charlie and Steve Utter’s wagon train brought in miners,
businessmen, gamblers, and prostitutes
30 wagons from Georgetown, CO to Deadwood, SD
They also created an express delivery to Cheyenne - 25¢ a letter
9. September 26, 1879 a fire broke out around Main St.
Destroyed more than 300 buildings including some
people’s entire belongings
The fire combined with declining placer deposits led many
to leave
Most businesses rebuilt better than before
Deadwood after rebuilding
10. Seth Bullock – Originally
came to Deadwood to open a
hardware store, eventually
became Sheriff and civilized the
camp
Sol Star – Opened a hardware
store with Bullock in 1876,
after it burned they built a
luxury hotel, Bullock Hotel,
which still stands – served as
both postmaster and later
mayor
Al Swearengen –
Infamous and brutal
owner of the Gem
Theater, he lured and
often beat women
into prostitution
11. Poker Alice – Cigar smoker
and prolific gambler, men
came from all over just to
challenge her
Potato Creek Johnny –
4’ 3” prospector who
found the largest gold
nugget ever in the Black
Hills
12. Wild Bill came to Deadwood via Utters’ wagon
train in July, 1876
August 2, 1876 Hickok was playing poker at
Nuttal & Mann’s Saloon
He normally sat with his back to the wall, but
he joined to game late and despite his pleas
with Charles Rich to change seats, he sat with
his back to the door
Jack McCall, a former buffalo hunter, pointed a
gun at Hickok’s head and yelled “Damn you,
take that!”
The bullet hit Hickok in the back of the head
killing him instantly
McCall was tried twice due to the legality of
Deadwood and he was hanged March 1, 1877
13. Came to Deadwood in 1877 and
opened a grocery with his brother
Adams Brothers Banner Grocery
In the fire of 1879, it burned to
the ground, but they rebuilt
better than ever
They made a fortune and W.E.
became one of the most
prominent citizens of Deadwood
He bequeathed his very large
house to Deadwood and now it is
a museum
14. Women were at first in high demand
Sarah Campbell was one of the first
non-native women in Deadwood
Daughter of a slave
On Custer’s 1874 expedition as a cook
She stayed and prospected, and later co-
founded the Custer Park Mining
Company
The wagon train brought in over 180
prostitutes, including Madam
Mustache, Dirty Emma, and Dora
DuFran who owned the most
successful brothel in Deadwood
Madam Mustache
Dora DuFran
15. Martha Bullock
Wife of Seth Bullock
Worked to educate and civilize
Deadwood
Opened the Deadwood library in
1895
Calamity Jane
Frontierswoman who wore men’s
clothes
Worked as a scout for the Army
Joined Utters’ wagon train and
befriended them and Wild Bill
Hickok
16. During the gold rush, ~500
Chinese resided in Deadwood –
mostly bachelor laborers
1883 flood destroyed much of
Main St. and they rebuilt on the
preexisting rock walls – created
a series of underground tunnels
The Chinese liked the tunnels
to move their goods due to an
ordinance that the Chinese
could not be out past dark
Tunnels also home to several
opium dens
17. Two of Deadwood’s haunted
buildings – The Bullock Hotel (1894)
and the Franklin Hotel (1903)
The Bullock is reportedly
haunted by Seth Bullock
himself as well as other
various apparitions and
ghostly orbs
18. Black Hills mining began from purely placer deposits
1874 – Custer reported gold near French Creek
1875 – John B. Pearson found gold in Deadwood Gulch
By 1876, miners had claimed all land around creeks in the Black
Hills
1,000s of people still flocked to the area
Over 7,000 miners came through and around $1.5 M of gold
extracted during the rush
19. Treasure Wagons like this one would carry as much as $250,000-$350,000 worth
of gold in one shipment to Cheyenne – Heavily armed, they were still a target for
bandits…heavy gold bricks were at least a deterrent - $350,000 = 1,000 lbs
20. 1888 – J.K.P. Miller
founded Deadwood
Central Railroad
New railroad replaced
previous methods of
bringing supplies,
people, and gold in and
out of the Black Hills
21. While most were looking
for the easy placer gold,
some went looking for
the source – the Mother
Lode
By 1880, the rush had
died down and mining
turned almost entirely to
hard rock
Once the transient placer
miners left, Deadwood
became a more
respectable town
22. Discovered by Fred and Moses
Manuel, Alex Engh, and Hank
Harney in April 1876
George Hearst and other
investors bought the mine for
$70,000 in 1877
October, 1877 Hearst took
over the property and began
hauling in equipment
Moses Manuel
George Hearst
23. 1878 – an 80-stamp mill
was erected and began
crushing ore
1879 – Homestake went
public, one of longest
lived stocks on the New
York Stock Exchange
Hearst began buying up
all claims around the mine
- one of his employees
supposedly killed a man
not wanting to sell
25. While most of the other mines closed in early 1900s,
Homestake kept on going
Due to size of deposit despite relatively low grade
During the Great Depression, Roosevelt raised the price of
gold to $35/oz to help the economy – Homestake had a boom
During World War II, government classified gold mining as
nonessential and Homestake closed
Homestake Mine- 1900
Typical Ore
26. After the war Homestake
reopened but struggled
due to the price of gold
Nixon removed
government control from
gold and the price
skyrocketed – Homestake
had another boom in the
1980s
Since then the price of
gold fell and Homestake
ceased operations in 2001
27. Black Hills were off limits, but we went in anyway
Custer found gold and set off a gold rush that led the
government to seize the land
Gold rush led to lawless atmosphere
Placer mining during the initial rush led to more
sophisticated hard rock mining, which also led to the
civilization of Deadwood
Homestake Mine, the largest of Black Hills mines, was also
the largest and deepest gold mine in America when it
closed
Almost 50 million ounces of gold extracted from the Black
Hills with almost 40 million from Homestake alone
