Whiners Going on About Increasing Oil Production

[Note: Let’s get something straight here. I’m an industrial chemist and not a pencil-necked economist. I’m going to talk about some O&G economics from my industrial perspective. MAGA people are whining about increasing oil production to ease gas prices. My view is that these buggers are idiots, but I won’t say it like that. I’ll just discuss some pragmatics of oil refining.]

In an article published 10/1/24 in The Center Square the writer reports that a survey of voters in the key swing states of Arizona, Georgia, Michigan, Nevada, North Carolina, Pennsylvania, and Wisconsin that between 80% and 86 % of voters say that the price of daily necessities has gotten painful. Between 88 % and 94 % say they are concerned about inflation. This survey was obtained by Morning Consult/American Petroleum Institute poll obtained exclusively by The Center Square. “The poll surveyed nearly 4,000 registered voters Sept. 20-22 with a margin of error of 4%.”

From the article-

Some refining basics

I think there is some misunderstanding generally about how the oil & gas (O&G) business works. First off, it is a global market and is subject to supply and demand pressures from all over the world. Second, there is O&G supply and there is refinery capacity. One might suppose that increasing O&G production domestically would automatically lead to lower fuel prices at the retail level. However, refinery throughput is limited to its particular capacity and storage. And, why would O&G producers increase output to an excess just to lower prices at the retail level? Leaving money at the table is against the instincts of every businessperson and is contrary to the fiduciary responsibilities of executives to stockholders.

Refineries are usually operated at about 90 % capacity. Lest one think that refiners only need to tweak the throughput up a bit, it must be understood that it is unwise to operate a refinery or any other manufacturing plant at a constant 100 % capacity. Like any other factory, a refinery is subject to sudden or planned maintenance requirements, equipment failures, process upsets, variability in oil feedstock composition, hurricanes, variable demand in product spread or even infrequent operational error. A sudden unexpected shutdown can lead to a variety of complications as well as unleashing hazards at the large scale. Once a refining process line goes down, repair and restart can take one or more weeks to months to bring the process back to stable production.

A petroleum refinery is operated on a continuous throughput basis with series and parallel processing occurring simultaneously. Operating a refinery profitably is a complex job requiring a specialized skillset. As a PhD organic chemist, I am barely qualified to even set foot in a refinery, much less be of any kind of use there. Chemists may be found on site, but most likely in the quality control lab. These are the rarefied heights of the petroleum engineer.

A petroleum refinery is designed to take crude oil and gas inputs and shape them into an optimal spread of profitable products. The focus will be on maximizing the output of the most profitable products, especially motor fuels in the form of the various grades of gasoline and diesel. Your local gas station buys fuel from a wholesaler/distributor at a quoted price then sets a retail price depending on not just the wholesale price, but more importantly the local market prices and expected sales volume.

Operating a refinery is a continuous flow exercise and is a bit delicate. A refinery is a web of continuous unit operations each with an input stream from one unit operation and an output stream to another operation. Each unit operation has a specific task to perform safely and efficiently. These unit operations subject the input hydrocarbon stream to heating, fractionation by distillation, and each of the many distillate streams are then subjected to their own unique processing. Other operations include alkylation, hydrotreating, sulfur scrubbing, catalytic cracking, isomerization, catalytic reforming, heat exchange, more distillation, blending and finally transfer to storage. Each operation is designed to process throughput at high flow rates to afford the best production rate of finished goods.

Waste process heat is directed to certain operations and used for greater efficiency. Oil refining inevitably produces light hydrocarbons whose recovery produces diminishing returns for recapture or comes from pressure venting where the vented gases are not suitable for recycle. In this case these gases are sent to a flare tower and burned. The flare tower plays an important safety role as it burns away flammable hydrocarbon gases that might otherwise accumulate and spread near the ground, posing a serious fire and explosion hazard.

Naturally, this requires considerable coordination to manage the rate of output of one operation to the input rate of the next. In fact the whole plant requires coordination of rates of throughput, pressure and temperature. A refinery is constantly monitoring and adjusting individual parameters with automation and human oversight to remain in “tune”.

During the recent COVID-19 pandemic and the reduction in demand, a number of refineries were shut down for maintenance or upgrades and a few were shut down permanently. This created a bottleneck in refining capacity nationwide and there was a shortfall in overall refinery output, leading to higher retail pricing of fuels as demand eventually rose.

Today the USA both imports petroleum and exports it. The supply of crude oil and gas depends on contractual obligations and who is willing to pay the highest prices.

The United States in a net O&G exporter. Between imports and domestic output, the US is currently processing enough O&G for our needs with surplus to export. And what will an increase in domestic fracking really do for the US, again pricewise? It can increase the production yields at individual O&G wellheads bringing greater volume for the O&G producer over time. Done properly, fracking makes sense. However, if fracking provides a conduit for natural gas, oil or produced water into ground water, then it can be irredeemably harmful for those so affected.

Even if domestic O&G production is increased and released into the market, the near-term problem will be limited refinery capacity. The lead time for building a large oil refinery can be 4-5 years from design phase to commissioning. Permits, financing and societal pushback can add considerable time. Putting a complex refinery in the ground can cost $5-$15 billion. Startup and adjustment of a refinery is time consuming, complex and can be a bit hazardous. Accidents during startup and shutdown are not uncommon.

The politically popular opinion that what the US needs is an increase in oil production to drive down retail gas and diesel pricing rests on specious assumptions. The government provides regulatory oversight in many aspects of O&G production and refining. In my view, government oversight in regard to environmental protection and worker safety is of critical importance. Global free market control of O&G production and distribution, while often heavy handed and seemingly heartless, is the best model we have at present for production and distribution of hydrocarbon-based goods to consumers. For a historical example of government control of supply and distribution, we can look at the Soviet Union and its authoritarian centralized control of nearly everything. The Soviet model of governance and production of goods and services failed spectacularly by 1991. The leadership of the USSR dissolved the Soviet system themselves after concluding that it was no longer workable. For all of its many flaws, the overall western model of capitalism continued to thrive.

In short, it only makes sense to increase O&G production to keep retail fuel prices low if the refineries demand more crude to meet their distributor’s demand. Refined fuels could be imported for distribution here, but an uptick in storage capacity will likely be required. Refineries are fundamentally limited by their processing capacity. Refineries, like most manufacturing operations, are designed to provide an optimum output with the installed equipment. Greater throughput requires larger equipment or additional process streams

Anecdote: Every day I pass through the intersection of an east/west state highway and a north/south interstate highway. On the west side of this busy intersection there are four gas station/convenience stores competing for our gasoline and diesel business. Just a block to the west is a stoplight and at the four corners of this are three of the gas stations with direct access to the light. The fourth is not at the light so entry or exit to this station is not controlled by the light. During the early morning commute time, the four electronic signs indicate morning prices that invariably are $0.20 to $0.60 lower than mid-day prices. The tall electronic signs allow for convenient rapid response to competing prices. One station is beyond the single stoplight intersection, so both exiting eastbound vehicles and entering eastbound vehicles who need to turn left across uncontrolled heavy traffic have to wait for a break in the congested traffic. This is a competitive disadvantage for them. The other three stations have direct access to the stop light. Co-incidentally, the traffic-disadvantaged station nearly always has the lowest prices first. This tends to set the stage for a daily price war. This morning the 85-octane gasoline price was $2.719 at all four stations.

There are some plusses for the disadvantaged station mentioned above. Unlike the other three stations there is room for 18-wheelers to fill their tanks with diesel and park overnight next to a cheap motel and a Waffle House (Hey! Waffle House hash browns are the greatest). The left turn across traffic disadvantage to 4-wheelers is only a minor obstacle to the 18-wheelers using the station since they are apparently fearless in pulling into heavy traffic to execute a turn.

Econ 101 Conclusions

Like everything else, scarcity applies pressure on hydrocarbon prices up and down the supply chain- from wellhead to fuel tank. National politics can play a role in hydrocarbon pricing if it threatens to alter scarcity in some way. In chemical kinetics we are interested in finding the rate limiting step in a multistep chemical reaction. This step is the bottleneck that controls the overall reaction rate. In much the same way, a bottleneck in a supply chain will control the rate of output of a given product. The rate of delivery through the bottleneck controls the rate of wealth creation for those in the supply chain. To increase the rate of wealth creation, one must multiply the number of these bottlenecks in parallel or design a new bottle with a larger neck. Importantly, the rate of wealth creation can be a winning positive or a losing negative number. Excess capacity anywhere in the chain results from excessive money spent on unneeded production scale.

Note: There is much more to the macroeconomics of O&G production than what I have addressed. The economics of O&G production and distribution in the US depends on policy and regulatory factors as well as considerable anticipation and speculation (gambling) in the marketplace. Despite this, it is possible to make certain very broad statements in the context of general supply and demand principles. The finer, high resolution, details can be found elsewhere.

Zombie Oil & Gas Wells in Texas

Much has been written about the gas & oil industry in the US. My aim only is to highlight the leaking, not actively producing, oil & gas wells.

Many states have a problem with orphaned and zombie wells. Big ole Texas has a problem with orphaned and “zombie” oil wells also. Over time, oil and gas companies have been abandoning uncapped oil and gas wells in their eternal haste to produce “Black Gold, Texas Tea.” Inactive or non-compliant wells with delinquent organizational reports (Form P-5) for more than 12 months are called “orphan” wells in Texas. The state of Texas does have procedures for the disposition of orphan wells. Wells may be abandoned because of low output or the owners going bankrupt. It is possible to take over an orphaned well, though why would someone takeover a depleted orphan well or a low output well?

What’s worse, even the capped wells have begun to leak because of the corrosion and decay of well casings and plug material. The leak may be far down the hole or near the surface. These abandoned wells that are now leaking are called “zombie” wells. The zombie wells push up brackish water along with hydrocarbon liquids and vapors into the atmosphere and the surface soil as well as underground into the water table. Some underground flows are large enough that sinkholes form and fill up with polluted water.

The Oil & Gas division of the Texas Railroad Commission is responsible for “Regulating the exploration, production, & transportation of oil and natural gas in Texas.”

The Texas Oil & Gas Association has stated-

As can be seen, the Texas Oil & Gas Association seems to feel that it has done its job with orphaned wells. The Teflon-coated Texas Oil & Gas trade association did what trade groups are supposed to do- shield their members from public blame and immense liability.

One component of crude oil & gas is hydrogen sulfide (H2S) which resides in both the liquid and vapor phases. This component is capable of both oxidation in the air to form a series of variously oxidized sulfur products as well as elemental sulfur itself. Hydrogen sulfide is extremely toxic and prone to cause olfactory fatigue in humans. The odor threshold is extremely low which could lead one to safely vacate the area, but the “nose numbing” effect on the sense of smell can lead to a false sense of security and continued exposure. Most cases of intoxication occur in confined spaces, however.

In a way, drilling for and striking oil & gas is like opening Pandora’s box. The well can produce valuable oil & gas, but along with it comes produced water with undesired dissolved minerals, petroleum and drilling residues. It seems clear that the State has a compelling interest in the final disposition of the well. The driller or party who owns the drilling rights to the well should be financially responsible for its clean shutdown. Bankruptcy should not absolve a company from responsibility for trouble the well brings.

This post is limited to the issue in Texas but it can exist anywhere oil & gas drilling has occurred. Obviously, the oil & gas industry represents a massive amount of economic activity and consequently it has enjoyed a privileged position in American industry in terms of regulations. It is doubtful this will change but that doesn’t mean that the beady eye of scrutiny should blink.

Even if hydrocarbon vapors and other gaseous substances blowing out of wells were not greenhouse gases, can’t a case be made for capping-off wells just to prevent pollution? There is a mentality out there that holds that if some pollution action is not mandatory, then it is not necessary. Their response to a problem is often that they “met regulatory standards.” That is, they would have done less if they could have.

EIA Releases New Btu to kWh Energy Conversion Factor

The US Energy Information Agency, EIA, has just released a new energy conversion relationship for the British thermal unit (Btu) and the kilowatt-hour (kWh). It is 3412 Btu/kWh.

EIA Monthly Energy Review

I post this kind of petroleum-related information with the hope that more people will pay attention to large-scale energy in general and oil & gas in particular. It is fashionable to pooh-pooh the petroleum sector for several reasons but, like it or not, it is one of the pillars of civilization. If we are going to be steering it in some particular direction, we should know a bit more about it.

There is a great deal of fascinating technology in oil & gas extraction and refining. The funny thing is that when you learn more about a subject, the more level your viewpoint on it will become, to the plus or minus side.

Fracking with PFAS

According to an article in The Hill, the organization Physicians for Social Responsibility published a detailed report on the state of PFAS usage in oil and gas drilling operations including fracking. Note that many if not most states allow drillers to claim that the components of their drilling fluids are a trade secret and exempt from public disclosure. The quantities mentioned in the report are astoundingly large in magnitude. They report that “between 2013 and 2022, drilling operations have injected at least 261 New Mexico wells with 9,000 pounds of per- and polyfluoroalkyl substances (PFAS) for use in fracking,” Further, the article states that “During the same period, oil and gas companies injected more than 8,200 wells with a total of 243 million pounds of fracking chemicals — likely including PFAS — kept undisclosed due to “trade secret shields,” per the report.

[Note: A reader rightly pointed out that 9000 lbs divided by 261 wells works out to only 34 lbs/well in New Mexico. My thinking was that adding PFAS release to an untenable situation where oil & gas operate under loose environmental constraints already was a step too far. The aforementioned 243 million lbs of fracking chemicals gives no indication of how much, if any, PFAS is included. I understand why additives are blended in with drilling fluids and there are many strong technical and economic reasons for it. There must be boundaries on how much pollution we produce- even with oil & gas production.]

Fracking involves the injection of water, sand and certain chemicals at high pressure to fracture and prop open fissures produced in the formation for increased recovery of oil and gas. This is not a new technique. However, the oil and gas industry has seen to it that they can enjoy trade secrecy and immunity from much regulatory oversight while engaging in their operations. Their injection of chemicals into the ground has been subject to precious little oversight in terms of what and how much they can/should pump into the ground. Underground there is no air oxidation, weathering or photodegradation to break down the substances they pump into the ground. The immediate threat may be nil, but over the upcoming centuries, our descendants may drill into groundwater formations that have been contaminated by earlier petroleum operations. We should tread easily being mindful of our future civilization.

This blatant side-stepping of transparency by oil & gas is made possible through lobbying the local, state and federal government. If they get any push back, they drag out the old saw about jobs, jobs, jobs. No official, elected or appointed, wants to be seen acting against jobs. So, all manner of dubious ideas go forward with the blessing of our officials. We citizens fail to vote in sensible regulation because jobs, jobs, jobs. It doesn’t matter that jobs in oil & gas are famously in the feast or famine category, oil & gas companies always get their way.

Everyday I drive by unmanned oil tank batteries silently doing their automated jobs. The work force is reduced to truck drivers or supervisors visiting only periodically. The roughnecks and the crew who laid the pipes are long gone. At work I frequently train new employees who have left oil & gas because it was too unsteady.

Recently a few states have signed legislation to ban products containing forever chemicals within their state. No mention of well injection chemicals, but at least this is a start.

Oil & Gas Companies and Their Gaping Holes

According to E&E News, the government is releasing $560 million of a total of $4.7 billion to fund the cleanup of orphan oil and gas wells in 24 states. It is part of the Infrastructure, Investment and Jobs Act.

From the E&E article-

“Historic oil and gas activity in regions like Appalachia and the West goes back more than a century, with many old wells lost. Additionally, oil and gas price busts have left more wells abandoned, their original drillers out of business or difficult to trace. When left unchecked, those wells can release greenhouse gases like methane and pose combustion risks.

All told, states have flagged more than 10,000 high priority wells for cleanup, the first in line of a nearly 130,000 backlog of unreclaimed known well sites, Interior reported today. That number is expected to rise as federal funds bolster state efforts to identify hidden or lost orphans.”

According to a June 16, 2020, article in Reuters, drillers are required to pay a bond up-front to pay for remediation in case they go bankrupt. In reality, the system is a patchwork of state and federal regulations that are underfunded. The article goes on to say-

The U.S. figures are sobering: More than 3.2 million abandoned oil and gas wells together emitted 281 kilotons of methane in 2018, according to the data, which was included in the U.S. Environmental Protection Agency’s most recent report on April 14 to the United Nations Framework Convention on Climate Change. That’s the climate-damage equivalent of consuming about 16 million barrels of crude oil, according to an EPA calculation, or about as much as the United States, the world’s biggest oil consumer, uses in a typical day. (For a graphic on the rise in abandoned oil wells, click tmsnrt.rs/2MsWInw )

The whole thing is a century-long train wreck- we could have easily followed along as it happened. The extractive industries have a long history of leaving a hazardous and unsightly mess in their wake so there is nothing new here. Industry has socialized the cleanup cost and kept the profits.

It is pathetic that someone would even have to remind them to at least seal the damned well when they were done with it. Walking away from a well that is or could be venting natural gas and hydrogen sulfide is obviously unethical. Transfer of ownership or bankruptcy should be no excuse by statute.

States like North Dakota, for example, have statutes relating to wells having “abandoned well” status.

For various reasons, wells stop producing.  State law requires that the site be reclaimed and directs the Industrial Commission to oversee that process.

The upstream exploration and production (E&P) side of the oil & gas industry should collectively pay for this. However, like most businesses, they will only respond to the threat of added costs. But, we’re not asking them to split the atom. This issue could be solved at a single board of directors meeting at any E&P company.

Naturally, the oil & gas lobby will howl like banshees at the very notion of holding the industry responsible. Refiners and distributors of distillates, I think rightfully, will say that they are not at fault. So it has to be upstream.

But what about the owner of the mineral rights? Should they be free from liability? Not being a legal scholar, I can only surmise that this is old turf.

A modest excise tax on every barrel of oil or every million cubic feet of gas would accumulate into a sizeable fund over time. But would E&P companies just leave every abandoned well uncapped thinking that they have already paid for it? Hard to say. There would be legions of corporate cost accountants and executives working on it though.

American voters have yet to elect a congress or legislature that will write law to hold E&P oil & gas or somebody responsible for the blight that oil & gas brings. The industry lobby knows that all they have to do is float out the twin dementors of lost jobs and economic despair to frighten the public into submission. Works every time.

When Colorado tried to pass a ballot initiative recently to ban oil & gas well operations within some expanded distance from residential neighborhoods, the industry had employees on the streets protesting even in my own small bedroom community. They seemed convinced that their livelihoods were in imminent danger. The initiative was voted down. Basically, it would have barred most drilling within cities. Would this have cost jobs? Well, I think that the frosting on the cake would have been ever so slightly thinner.
