CO2 utilization vs. storage: why store it?

  • 1.  CO2 utilization vs. storage: why store it?

    Posted 12-19-2016 05:06 PM

    CO2 capture and usage as a miscible flood solvent makes much more sense than storage, since CO2 is generally the best known solvent for oil. Miscible flooding as a primary recovery method could make energy production far more efficient, even including capture and transportation costs (as opposed to primary depletion followed by waterflooding followed by miscible or other EOR method), where it is applicable -  which is generally to light to intermediate-weight oils.  Unfortunately, it seems that convention (definitions/practices of primary, secondary, tertiary recovery) and policy and regulation effectively prevent it.

    Miscible recovery is limited only by sweep efficiency. The simple wag (water-alternating-gas) CO2 flood in SPE5 (Killough, J., and Kossack, C., "Fifth SPE Comparative Solution Project: Evaluation of Miscible Flood Simulators", SPE 16000, presented at the 9th SPE Symposium on Reservoir Simulation, San Antonio, TX, Feb. 1-4, 1987) demonstrates that – it gives about 79% (primary) recovery of an initially undersaturated oil, and about the same recovery if we change the rich injected gas to CO2.  Water is injected alternately to reduce gas mobility and override of the oil.  And, if anyone believes that it’s important, at the end of the CO2 primary wag flood 90% of the injected CO2 is sequestered.  If the original problem is changed to first deplete, then waterflood, and then wag flood (20 year depletion, bhp=1000, followed by 20 yr waterflood, bhpp=3000, bhpi=4500, followed by 20 year WAG flood), simulated oil recovery is only 74% in total (27.1% in primary and 60.2% after waterflood).  Depletion and waterflooding destroy the possibility for very high miscible recovery because they eliminate the possibility for uniform and high sweep efficiency.  Recoveries are on the high side here because of the light oil and because of the confining quarter-five spot (reflecting recovery by wells in interior patterns).

    My question related to miscible recovery and CCS, is if you’re going to go to all the expense of capturing and transporting CO2, why would anyone want to waste it by storing it underground rather than use it for miscible or near-miscible (primary or EOR) recovery?

    No replies to my question here or to any of my questions in other discussions indicates that there is no valid reason to store CO2.

    Which makes SRMS not valid.  Most issues of CO2 storage (beyond its false justification) can be treated only by reservoir modeling.  Redefinition of common words indicates inability.  SRMS and PRMS are both incompetent, because they do not use any valid statistical or probabilistic method to treat uncertainty, and the definitions make no sense (they actually define the value of all reserves as 0 - see Reserves Definitions).  How to robustly quantify uncertainty using any model is described with examples at Uncertainty Quantification in Reservoir Modeling - P10 P50 P90 and at SensorPx - A Simple Component of Probabilistic History Matching, Forecasting and Optimization.

    .I believe that we are the world leaders in this subject and know far more about it than any "climate scientist".  It is absolutely impossible to calculate a global average temperature from sparse periodic temperature measurements.  That simple fact invalidates almost all literature by "climate scientists" claiming global warming.  All that literature is also invalid because there no valid substantiation of any such claims in any publication.  We are also world-leading experts on that subject.  I have personally refuted a large number of false claims regarding reservoir modeling in very many public discussions, using the scientific method to prove it through example, mostly here on the old Simtig and in the Reservoir group and on LinkedIn.  That is also demonstrated throughout our company website.

    Brian,

    If it's answers you're looking for, as opposed to letting steam out, I'd be glad to give it a try. In exchange it would be good practice to start a thread for every 1-2 questions instead of piling them up so answers become doorstoppers (and people stop reading them). How about global average temperatures? Would you like people to comment on your statement that it's impossible to compute such a thing?

    Mind that when you write "climate scientists", you seem to personalize science and focus on the people that generate and validate ideas, as well as their motives. This is redolent of the scholastic principle of "he said it himself" (him being Aristotle), which kept haunting science more or less until Descartes said "screw you, old man, it's not who says something, but the method they use to reach their conclusion"; to rephrase another philosopher, "scientist is as science does". Since scientific method is applied to climate, then we speak of climate science. Whoever tries their best at it and submits to the humbling rigors of peer review and independent validation, well, they are scientists alright to me.

    Looking forward to a heated, and doubtless man-made (sorry, anthropogenic), discussion,

    Mateo and all reading this thread:

    With no explanation our recent discussion of the validity of the science behind the AGW theory, which resulted in promoting CO2 sequestration for no other reason than trust in the AGW science was removed by SPE. I ask the moderator if this is censorship of scientific discussion on the part of SPE?

    However, I am providing a simple discussion of solar flux data I measured here in Denver this month, to illustrate that the normal scientific process of discovery has not happened in the case of the AGW theory.

    It's the Sun that Drives Temperature, Not CO2

    If anyone harbors thoughts that CO2 is driving climate look at the plot below. Notice the diurnal increase in solar flux precedes the temperature maximum for the day by 2 hours. Now this time plot could prove the negative that solar energy does not drive temperature if the increase in temperature preceded the increase in solar flux. The ice core data from Vostok as analyzed By Professor Ian Clark shows the increase in ice core temperature proxy precedes the increase in trapped CO2 concentration by 800 to 1000 years, yet people promoting the AGW theory  have hijacked that data to claim the opposite. See the attached document proving this claim.

     

    Now you all know that while correlation is a necessary condition to prove a cause and effect relationship between these two variables, it is not a sufficient condition. So the scientific process requires that scientists look beyond the correlation to establish that a change is solar flux does cause earth temperature to increase. Using the scientific method, we have to prove there is no other forcings that are not included in the time plot below are causing temperature to change. So for example we can analyze the CO2 concentration in the atmosphere on the night side of earth to see if it is different than the CO2 concentration on the daytime side of earth. If the two concentrations are the same we can eliminate CO2 as what is driving temperature change, but that still does not prove that sunlight causes the earth to warm.

     

    To prove that we need to apply all the existing science related to radiant heat transfer and thermodynamics to establish a 'theory' that the power of the sun is driving climate. At this point in the scientific method of discovery it remains a 'theory' that can be challenged by any scientists who reevaluates my data, which I openly provide to him.

     

    This is the scientific method related to the AGW theory has been prevented by the bullies peddling the AGW. The science behind the AGW theory has never been tested by the normal process of scientific discovery. People who collected and manipulated the raw data  have refused to release their raw data for any scientist who wants to reevaluate it and their conclusions.

    I do not agree with Steven Merritt that the SPE is not an appropriate place to evaluate AGW science.

    Am not aware of any content having been removed. The discussion seems to
    have migrated from Reservoir to CCUS - perhaps that’s an explanation and
    the string you’re looking for is on the other board.

    Hope you can join the September 19th webinar with David Hone.

    Others are in the pipeline some with a panel not just one speaker. You
    might like to speak yourself ?

    Let me know and we can work together on creating a multifaceted panel
    webinar.

    Kind regards

    Brian,

     

    In reference to your articles, I have tried to address all in regards to the strong effort that has been given to those of us in the Industry that have promoted the use of CO2 as a means to recover additional tertiary oil, either in current CO2/EOR operations or CO2/SEQ future applications.

     

    Tertiary Oil Recovery – The third stage of oil recovery

    Tertiary Oil Recovery with CO2 injection (CO2/EOR) has been the mainstay of the Permian Basin for over 44 years. In that time over 1.5 million barrels of tertiary oil have been produced which accounted for over 250,000 BOPD in the Permian Basin alone in 2014, and provided over 20% of the oil production in the United States. In addition, the inclusion of the Residual Oil Zone (ROZ) has added a significant target for Green Field Development (Billions of barrels of oil). However, with today's oil prices,  all areas of the World are currently distressed due to the 60% reduction in oil revenue. The Permian Basin CO2 world is of no exception even though the Permian Basin Shale Oil plays are still attractive and profitable. In the new Millennium, the question becomes "At what point will Tertiary Oil Recovery fill the "Energy Gap" that exists between World Oil Energy Supply versus World Consumption?" Shale Oil Fracking will certainly advance quicker to "Fill the Gap", since it may require a significant investment up-front, but also generates a quick return with moderate risk. The Wall Street guys are still amored by this, even in a 40$-50$ environment. The question becomes at what time will Wall Street recognize the ROZ as a strategic play for "Greenfield Development" which requires a large investment with longer payouts, but much longer project life, with lower oil recoverable risk, but more susceptible to oil price fluctuations. For us that lived through the oil price crashes of the late 1980's operating CO2 floods, proper pattern WAG adjustments were implemented to ensure efficient flood operations that drove us through several low oil price environment periods, but still remained profitable. In addition, CO2 Source is and will always be the driver for advancement of CO2/EOR. To date, the biggest obstacle hindering the advancement of CO2/EOR is  Cost of Capture. The best example of this is the Gulf Coast Region. The Gulf Coast CO2/EOR Resource is extremely large with billions of recoverable reserves and multiple CO2 Sources. To date, CO2 Cost of Capture hasn't come down far enough to make it economically attractive for large scale implementation, and represents the biggest obstacle for advancement into the future.

     

    CO2 Sequestration – (Power Plants, Refineries with Source-to-Sink  Analysis) (Dot-to-Dot)

    Tertiary Oil Recovery with CO2 Sequestration (CO2/SEQ) has been pursued by both the government and oil industry since 2000, targeting the Midwest, Gulf Coast, Rocky Mountains, and California. Over that time, we have seen it grow, expand, and contract. Mostly due to the high cost of CO2 Capture, but also due to government interference (Politics, both on the Democratic side as well as the Republican side). Today, it all depends on how Trump expects to save the coal industry. Clean coal means sequestering the CO2, either for CO2/EOR or for deep saline injection. CO2/EOR has to be profitable. Deep Saline needs to be better understand in regards to uncertainty. Since you mentioned Deep Saline Injection. The reason why Deep Saline Injection is necessary is due to the large amount of CO2 Storage that can be stored without interruptions, which when compared to the amount of CO2 that can be sequestered in CO2/EOR projects, which is much smaller and requires a multi-field multi-phase plan for implementation over time. The uncertainty in deep seated aquifers comes from the fact we really don't understand the effects of pressure on deep seated fault systems and whether we need to also produce brine on the other end in order to maintain material balance pressure integrity within these aquifers. The produced water could turn the Permian Basin into an area blanketed with "Green Houses" along with oil field development. That sure would be a sight.....   

     

    Global Warming

    As Reservoir Engineers, we experience climate change every time we look at a log. Transgressive-Regressive sequences are the cornerstone of our industry when it comes to log interpretation especially in carbonate reservoirs. The Permian basin is flanked by transgressive-regressive sequences throughout the Permian time frame. Both the Main pay and ROZ zones show these influences. Climate change would be reflected in sea water rise and fall, which we have all seen and read into Petrophysical analysis.

     

    Over man's documented past history over the past 500 thousand years, climate changes have also occurred. 75 million years ago the Toba volcano spewed ash over much of southern Asia killing people and altering climate for years and 39 million years ago the caldron which underlays Naples Italy spewed ash over much of Eastern Europe, which may have led to our early ancestral Neanderthal relatives vanishing or due to the dwindling population blending into modern human migration out of Africa (DNA (3%)). Even over the past 10,000 years, many of our ancestors had to relocate at the end of the ice age when sea water rose and flooded the English Channel and other places around the World. (Note: the Biblical Flood mmm....)

     

    The True Question:  "Will Coal's Future shift under Trump?"

    How will the conversation on coal change once President-elect Donald Trump is inaugurated next year? Will Carbon Capture be a focus for the new administration? Will "Clean Coal" contain economic incentives to the CO2/EOR community like it did with the EOR Tax Credits that drove the CO2 industry in the early 1980's. Will the Cost of Capture come down to the point that it is economically attractive everywhere around the World recovering all that oil we left behind under Primary and Secondary Waterflood operations? Can CO2/EOR compete with Shale Oil Fracking economically to fill the "Energy Gap" that exists in the 21st Century?  

     

    Several of these issues are addressed in my SPE and Carbon Management Technology Conference (CMTC) papers:

    The rapid growth of temperature without doubt has to do with human practice, We must be aware and more than anything, we must make conscience and make something respect for the environment. We might be wrong in our predictions due to the complexity, the uncertainties are role important and subjects of thorough scientific research. I think that  the use of CO2 in the industry and CO2-EOR technique is an alternative economic that must continue growing in the future, case keeps growing consumption of fossil fuels.

    Depending on the location, processing and transportation costs could make ccs more economical than miscible flooding.

    Hi Brian,

    Screening studies conducted a decade ago in support of a CO2 Trunkline or Network in Alberta suggested that storage would need to be an integral part of the system, especially for start-up:
    - Infrastructure capacity would likely exceed initial usage by the trigger EOR project.
    - Demand would likely vary with oil price expectations and available CAPEX.
    - Pilots require less gas than commercial projects.
    - Unlikely that all EOR pilots can be commercialised.
    - Permits a competitive area development plan with a hub and spokes.
    Turned-out there were more legal and liability issues with storage and resale than we had or the regulator had anticipated. So, the project was pushed onto the back burner for a while. Also, because EOR still needed some additional fiscal incentives, etc....
    I remain hopeful that the idea will re-emerge in the not too distant future.
    Regards
    Bob

    Brian, what was the source of the CO2 in the project you are discussing?

    In the 1990s I worked on the oil sands in Alberta. This was a thermal recovery steam involving steam injection. We burned natural gas to generate the steam.

    I asked our engineering construction contractor who was designing and building our surface facilities to evaluate the prospect of capturing the CO2 we produced generating steam, isolating the CO2 from the N2, compressing and injecting to CO2 into a shallow coal seam to be adsorbed by the coal, strictly a CO2 sequestration project.

    he contractor did the calculations, not me, but he told us he did an component material balance for CO2 covering the entire project, and told us that we would generate more CO2 providing the energy to drive the compressors than we would sequester in the coal seam.

    Have you ever been involved in any pure CO2 sequestration projects? If you have would you do a CO2 material balance and tell us if you can sequester more CO2 than is produced by the sequestration project?

    If you don't have data to do this from a project you know of or have been involved with, can you give me a link to the raw data so I can do such a material balance on CO2?

    ​Hi Bob,

    That's a potentially valid reason for temporary storage prior to usage, but my question was regarding the permanent storage and sequestration of CO2, for which there is absolutely no valid reason or possible benefit.

    Thanks,
    Brian
