Juan José Arreola’s House in Ciudad Guzmán, Jalisco, Mexico: Visit on the 100-Year Anniversary of the Author's Birth

Juan José Arreola’s house sits perched on a hill with a stunning view of the city, the valley, and the Colima volcano. When you pass through the gates, you are in a walled garden, and a house that has many levels. It has been converted into a gallery and cultural center. When I visited, there was an exhibition of “papel picado” (pierced paper) the perforated paper flags that are hung across streets during holidays and fiesta. Most were celebrating Dia de los Muertos.

Juan Jose Arreola's home in Ciudad Guzman, Jalisco, Mexico

There are interesting pine trees and jacarandas, along with other flowering trees. Supposedly, Juan José rode around town on his bicycle, his wild hair flowing. He made an impression in the 1950s with his innovative fictions, which combined a kind of Borgesian surrealism with whimsy and irony. He is considered a quintessential Mexican writer who incorporated many of the traditions, values, and language of his home, Jalisco. Because of the Guerra de los Cristeros, Arreola had to drop out of school after the 4th grade, at age 8. After that, he taught himself everything he knew, which included acting, writing, and working with book construction.

Arreola was known for his prodigious memory for poetry and drama, which must have helped him develop his ear for language, and also to incorporate the world around him. Further, having such a deficit of formal education might account for Arreola’s flamboyant dress and behavior – it would provide armor in a very hierarchical and snobbish literary world.

At the same time, Arreola did appear on the scene at precisely the right time, when artists such as Diego Rivera and Frida Kahlo were championing the authentically Mexican. In being an autodidact, he reminds me of Charles Dickens. I had the good fortune to visit Arreola’s home on precisely the 100th anniversary of his birth, just when a reading / presentation was wrapping up.

My friend and I were both given a gift of his book of whimsical short stories, Confabulario. I’ve read a few of them. I find them absolutely delightful. “Rhinoceros” shimmers with a delightful schadenfreude as the divorced wife of a choleric and abusive judge (the “rhinoceros”) is tamed by a quick-witted (but selfish) new wife; he lives an enforced and circumspect life… only wonders why he allowed himself to be converted into a docile, slightly malnourished vegan.

For all who have had to deal with a brute, it has a Dantesque symmetry as the judge experiences his own “contrapasso.” There is tremendous wisdom in Arreola’s “beast fables” – here’s a quote from “Girafa” which perfectly captures the ironies of the human spirit, and the resulting divisions, splits, and double-edged blessings and gifts:

With such wasted technique, which makes it really challenging to both gallop about and to love, the giraffe represents better than anyone the delirious ravings of the spirit; it looks in the heights for what others find on the surface of the earth. (a loose translation of a paragraph from "Girafa") 

Another of my favorites is a discussion in a movie theatre about whether or not the devil got a good deal when he bought the soul of what the commentator in the story considers to be something of a ne’er do well spendthrift. It reminds me a bit of O. Henry’s “The Ransom of Red Chief” – kidnappers kidnap a child who is so annoying that by the end, they are paying the parents to take him back.

I breathe deeply and enjoy the woody, slightly spicy aroma of the woods and flowers. I realize we’re between the “sky islands” of mountainous pine forests, and then the chaparral scrub in the valley floor toward the Colima volcano. The volcano is active, the earth is capable of passion and violence, and, as in the Guerra de los Cristeros, is probably inevitable, but unpredictable in its impact.

A Probing Look at Bolivia's Energy Investment Opportunities

If global analogues such as the Permian Basin or West Africa are any indication, Bolivia’s certified reserves will undoubtedly increase dramatically with a better understanding of the geology and with the application of new technologies.

Bold New Exploration in Frontiers; Revitalization in Mature Fields
I recently had the opportunity to participate in the First International Forum for Gas, Petrochemicals, and Green Fuels, August 28 – 31, in Santa Cruz de la Sierra, Bolivia.

Foro Internacional del Gas, Petroquimica, y Combustibles Verdes / 28 - 31 Ago 2018 / Bolivia

A few months earlier, the American Association of Petroleum Geologists (AAPG) hosted its first ever Geosciences Technology Workshop in Bolivia. It took place June 6 – 8 in Santa Cruz. Some of the presentations are available here: http://www.searchanddiscovery.com/specialcollections/lar.htm

AAPG GTW June 2018

The August International Forum featured opportunities for investment in exploration and production of natural gas, infrastructure and marketing of gas, petrochemical production, and biofuels. http://www.energypress.com.bo/sugieren-una-sinergia-entre-ypfb-y-operadoras/

I was impressed by the opportunities to drill for new gas reserves in the southern part of Bolivia, to improve production in the mature fields, and to invest in gas pipelines.  I was also impressed with the biofuel (biodiesel and sugar cane-derived ethanol). LifeEdge inteview:

LifeEdge Interview, Chatting about Bolivia

The recent rise in the price of oil makes investment more attractive.  Here’s an article:http://www.lostiempos.com/actualidad/economia/20180903/precio-del-petroleo-es-oportunidad-mejorar-exploracion-bolivia

Transportation Hub in the Heart of Bolivia
Bolivia’s goal is to become a natural gas hub for all of South America. This is a very interesting plan, which takes advantage of the twin blessings of Bolivia: mineral resources and central location.

By having pipelines crisscrossing the country, it’s possible to have natural gas travel from fields in Bolivia to major markets, which include Brazil, Argentina, Chile, and Peru.  It’s also possible to facilitate the transport of gas from fields in Argentina to Peru, or from Peru to Brazil, etc.

Logistically, becoming a gas pipeline hub makes sense.

There are a few challenges, however:
1.  Pipelines need to stay full of gas.  Is there sufficient supply? Are there enough pipelines? Enough gas?  Enough pressure? There is for now, but the future will require more.

2.  Political stability is vital. Bolivia has a huge advantage in this area. For example, Ecuador is now experiencing problems in its petroleum-producing provinces.  Peru has become more stable than in the past, but there are still some outliers of violence. In Colombia, insurgents murdered three young professional petroleum geologists in September who were working in the Antioquia province. That said, there are some remaining issues with Chile (see article).

3.  Economic stability is critical.  If there is hyperinflation, there are always problems with day to day operations, as well obtaining spare parts, due to liquidity issues.

4.  Nationalization factor:  A plan to decrease the royalties (or taxes) paid to the government act as a tremendous incentive. If the government has (or states that it has plans to) nationalize foreign operations or companies, capital (as well as expertise) tends to flee the country.

5.  Transparency factor:  Governments that maintain transparency in the way that they attract investment, award contracts and concessions, are very likely to maintain stable investments.

6.  Wall of tariffs:  The world’s great empires tended to grow into empires through trade. Yet, paradoxically, when they feel threatened, they tend to engage in protectionism. Walls and trade barriers can be digital as well as physical and can apply to just about everything.

7.  Streamlining bureaucracy: Bolivia, like Peru, has done a great deal to streamline the process of doing business in Bolivia by reducing the number of permits needed.  It’s a good idea. After all, if you need 50 permits in Country X, while Country Y requires 5, where do you think people will likely do business? Time is money. Delays are painful, and, where there are tedious documents to be filled out and submitted through a bottleneck, there are often “facilitators.” So, requiring too many permit may trigger corruption.

8.  Natural gas can be used as feedstock for urea and other fertilizers. Special transportation is planned for urea, which will have a positive influence on the extensive agricultural sector near Santa Cruz.

9.  Natural gas can be feedstock for petrochemicals; specifically for low-density polyethylene (used for plastic bottles and bags) and also for polystyrene; used in cars, etc.

10.  Using sugar cane as feedstock for ethanol.  Being able to sell to more than one buyer creates a tremendous opportunity for small producers to diversify and also to justify much-needed capital improvements.

A Bright Future, Given Solid Governmental Partnering
The outlook for Bolivia looks very bright on many fronts.  In fact, one can already see progress as the city of Santa Cruz de la Sierra continues to experience tremendous growth, not only in natural gas, but also in the manufacturing and agricultural industries made efficient by the availability of energy.

AAPG Basic Wireline Log Interpretation (Petrophysics Technical Interest Group

The 2-day course "The Basic Wireline Log Interpretation" is designed to teach people who are not petrophysicists, but are in need of incorporating wireline log data and some basic log interpretation in their daily work.  The course will take place October 22-23 / Halliburton Campus Room TC-1214, 3000 N Sam Houston Pkwy E, Houston, TX 77032-3216 

(Note that the cost is only $300 for a full two-day course, with lunch and materials.)

Another goal of this course is to illustrate not only on how to understand the logs responses but also to know the wireline log data acquisition process.

The Course will begin with the principles and scope of the tools (gamma ray, resistivity, density, neutron, Sonic, image log, etc.). This will include the basics of the tool physics as well as how to apply the different responses to discern reservoir properties such as porosity, hydrocarbon pore volume, reservoir deliverability, etc.

There will also be some basic exercises that will be handed out to try real world problems using open hole wireline logs.

In addition, the class will take a field trip on Halliburton campus to the Test Well facility to see an actual logging job. While their wireline engineers will explain what one would need to know to acquire data correctly and instructors will explain how knowing this can be useful to log interpretation.

Lastly, the class will have an open forum for approximately an hour in talking about the challenges the students may be facing in their projects as well as viable solutions.

For the purposes of this class students will not need a computer for activities but as we as an industry are always on call computers are welcome in the class.

Additionally, no open toed shoes will be allowed for the field trip portion of the class.

Lunch will also be provided.

Machine Learning and Python: Interview with Patrick Ng

The United States is now the world's largest producer of oil and gas, and machine learning played a large role in the transformation, which has occurred because of new techniques and technologies.

Welcome to an interview with Patrick Ng, geoscientist and pioneer of innovative ways to use analytics and specifically machine learning, to find new oil and gas reserves and to produce them more efficiently and sustainably.

https://youtu.be/6uQR8PO3l3A

LIFE EDGE with Patrick Ng Chat 2018 Q&A Notes

Background - I am a geophysicist by training, and experienced A to Z in  geosciences. 1) As - AVO amplitude versus offset to reduce risk, azimuthal features to map natural fractures, 2) transform seismic to rock properties, and 3) prestack depth imaging / model building to map subsalt reservoirs leading to 3 giant discoveries total over 2.5 billion boe in the Gulf of Mexico, and 4) the Z is drilling wells and learning from the drill bit all the way to total depth (Z).

And I learn through the drill bit that we drill anything but an average well, or rather a range of IP initial productions. The risk lies in the spread, and I make it a business managing risk at Real Core Energy.

Q1: how about examples of using Python in industry?

The hackathon focus was production forecast of a well. Given the flow rate data (courtesy of Halliburton, sponsor) and Python Notebook as template, and bootcamp to bring everyone up to speed. The exercise is to try use geoscience in machine learning, and play with the number of layers and neurons in neural network, and improve the forecast accuracy.

Q2: why Python?

Python is like the foundation, that my teenage daughter uses for make up. Depending on the event, she will put on other colors and things (not sure what to call those… so I won’t).  And the real power of Python comes from a set of libraries. For example:

1) Numpy, numeric Python for vectorized numerical computation
2) Pandas for handling lots of columns and rows
3) SK learn for machine learning algorithms, ready plug-n-play.

Think of.Python example, say write a few lines of codes, in a loop do something to each element in an array one at a time.

Numpy can collapse that into a single line, operates on an entire time series as a vector all at one go.

Often we may have a thousand wells, each with its production profiles. Think of wells as columns across the top with number of barrels per day, week or month hanging down. Pandas can operate on the entire collection of series of data all at once, like getting the mean, median, statistics with one line on an entire group of data. We also get the top 25%, next 50% and bottom 25% percentiles. Quickly we get a feel for how well the producing assets perform.

Q3: why is Python so popular with  machine learning?

It has to do with the availability of powerful libraries like Keras and Tensorflow well suited for neural network and deep learning. While SK Learn has been around for some time, Tensorflow was released by Google to open source consortium in November 2017.

Lets take deep learning as example. Microsoft had success using 158 layers in a deep neural network. Using keras, we specify one layer at a time, and we’d have 158 lines of codes.

But with Tensorflow, we can do that in one line albeit a long line, by listing the number of neurons in all 158 layers all at once. Again fewer lines of codes. But if we want to customize, and tune each layer, then we can do so with Python in a more granular way.

So we go from Python (the foundation), to Numpy, Pandas, Keras and Tensorflow, each provides the tools to do more, faster with fewer line of codes. In a nutshell, Python opens up a whole new way for geoscientists to explore data, do rapid experiments and gain new insights.

Q4: can machine learning make the industry more safe and clean?

Here are two examples. First predictive maintenance, we can better anticipate and schedule downtime for routine maintenance and repairs of equipments. Just as we do annual check up for our AC in Houston and keep them running top shape. That will prevent potential leaks and minimize surprises, so keep us safe.

On cleaner environment, one possibility is that we drill fewer wells and produce the same volume, if we can better predict the outcome with machine learning. Doing so, we reduce the footprint and impact on the environment.

(One more thought came after the Chat, is refracking. If we can use machine learning to better identify refracking candidate wells, we shall improve recovery factor and may also drill fewer new wells. Again reduce footprint and lessen impact on the environment.)

Q5: is there benefit of reprocessing data and machine learning together?

Yes. It has been standard business practice that every few years, with improved algorithm, we reprocess data, get higher resolution and a more detailed look. Like going from 4K to 8K HDTV, instead of 80 to 100 feet resolution in seismic, we may get that down to 40 ft. With higher resolution data, we’d retrain machine learning and get better results. Both go hand in hand.

That brings up a good point. In the world of geoscience, if we change the model, we also get different resulting imaged data. Unlike typical data used to feed machine learning algorithm, say what I bought from Amazon or movies streamed from Netflix, what I read and watched became record. That won’t change. But when imaging seismic, the model and resulting data are tightly coupled. Change one, we change the other.

So learning with machine beats machine learning alone.

Before 1995, the thinking in Gulf of Mexico was that salt bodies would become detached because of buoyancy (density of salt is lighter than that of surrounding rocks). So over time in geologic scale (millions of years, not weeks), salt moved up from great depth and ended up what looks like cup cakes (picture inside the lava lamp). But with the Crazy Horse (now called Thunder Horse) discovery, we learn there is salt mountain that goes forty five thousand feet deep below the seafloor. No cup cakes.

Python is a tool that can geoscientists explore and test their ideas with data. Better understanding of the geology and producing more. Last but not lease, is that Python while really powerful for numerically intense applications, it can go all the way to voice. Using Python-Flask libraries, I put together numerically rigorous app and deliver via Alexa.  That I see can draw more highschool students interested in geoscience.

Closing

As a closing thought, remember the old saying “The journey of a thousand miles begins with one step.” I see learning python is the first step. Just do it!

 Thank you, Patrick! 

Bolivia Plans to Expand Gas, Electricity, Green Fuel, and Petrochemicals Exports

Bolivia intends to expand its exports of LNG, electricity, petrochemicals, and green fuels in 2019 and beyond, announced the Bolivian Vice President, Alvaro Linero Garcia. In addition, exploration to develop reserves of gas are being encouraged through partnering with companies to conduct studies and to drill exploratory wells. In addition, mature fields will be the target of study and investment to revitalize the reservoirs through enhanced recovery methods.

Panel discussion with Luis Sanchez, Minister of Bolivian Ministry of Hydrocarbons, with experts discussing opportunities and expanded reserves.

The announcements were made at the closing ceremony of Bolivia's First International Forum on Gas, Petrochemicals, and Green Fuels, a four-day event in Santa Cruz (August 28-31) that had as a goal to encourage investment, and in doing so, presented a wide array of potential game-changers for partner companies, investors, and Bolivia.

With a goal of stimulating investment in exploring for hydrocarbons, the Minister of Hydrocarbons, Luis Sanchez, detailed the opportunities to participate in more than 10 blocks in Bolivia, many in the prolific Tarija and Chuquisaca regions.
