“Deep Geothermal Is Closer Than You Think”

Posted in CCS, climate, energy, tagged , , , on November 17, 2022| Leave a Comment »

Update on the most promising renewable energy alternative:

Quaise has received a grant from the Department of Energy to scale up Woskov’s experiments using a larger gyrotron. With the larger machine, the team hopes to vaporize a hole 10 times the depth of Woskov’s lab experiments by the end of this year. After that, the team will vaporize a hole 10 times the depth of the previous one — what co-founder Matt Houde calls a 100-to-1 hole.

“That’s something [the DOE] is particularly interested in, because they want to address the challenges posed by material removal over those greater lengths — in other words, can we show we’re fully flushing out the rock vapors?” Houde explains. “We believe the 100-to-1 test also gives us the confidence to go out and mobilize a prototype gyrotron drilling rig in the field for the first field demonstrations.”

Rather than getting deep in the weeds of carbon capture, imagine powering those existing facilities with steam generated without carbon emissions at all.

The key is that ultradeep geothermal has the power density and scalability of fossil fuels.

What’s next for Exxon’s sequestration leases?

Posted in CCS, Gulf of Mexico, tagged , , , on October 25, 2022| Leave a Comment »

Offshore

Per BOEM’s leasing data base, all 94 of the Sale 257 “carbon sequestration leases” (blue) were issued with an effective date of 10/1/2022. However, Sale 257 was an oil and gas sale, and the leases do not convey carbon sequestration rights. Each lease will expire in 5 years absent oil and gas production or ongoing drilling operations.

These oil and gas leases may not be repurposed for sequestration or other purposes unless an alternate use RUE is issued competitively in accordance with 30 CFR § 585.1007.

So what’s next for these 94 leases, 31% of the entire sale?

Action by DOI on Lease Sale 257 required in 15 days

Posted in CCS, climate, energy policy, Gulf of Mexico, Offshore Energy - General, tagged , , , on August 31, 2022| Leave a Comment »

Per legislation signed by the President on Aug. 16, 2022:

(b) LEASE SALE 257 REINSTATEMENT.—
(1) ACCEPTANCE OF BIDS.—Not later 30 days after the date of enactment of this Act, the Secretary shall, without modification or delay—
(A) accept the highest valid bid for each tract or bidding unit of Lease Sale 257 for which a valid bid was received on November 17, 2021; and
(B) provide the appropriate lease form to the winning bidder to execute and return.

The Department of the Interior has been silent on their implementation of this provision. We are particularly interested in:

  1. how the 94 carbon sequestration bids will be handled
  2. whether any bids will be rejected on fair market value grounds

Is the Sale 257 victory dance premature?

Posted in CCS, energy policy, Gulf of Mexico, Offshore Energy - General, tagged , , , , on August 22, 2022| 1 Comment »

Contrary to some media reports and industry comments, the Inflation Reduction Act does NOT require the Department of the Interior (DOI) to award leases to the high bidder on each Sale 257 tract. The legislation requires DOI to accept the highest valid bid for each tract.

As BOE has previously explained, the 94 carbon sequestration bids were clearly not valid, and leases should not be awarded. These bids accounted for 30.5% of the entire sale in terms of the number of tracts receiving bids. (More on the CCS bids.)

There is also the matter of fair market value. Only 9 of the 214 (non-CCS) tracts received more than one bid and none received more than 2 bids. DOI/BOEM may determine that some of the bids did not pass the fair market value test. Are such bids “valid” under the terms of the IRA legislation? Note that 7 of the 93 high bids submitted at the previous sale (Lease Sale 256, November 2020) were rejected on fair market value grounds. All 7 were single bid tracts.

Lastly, there is the unresolved matter of the decision by Judge Contreras to vacate Sale 257. While the legislation seems to clearly supersede that decision, who knows what might happen next on the litigation front.

Alarmist leasing rhetoric resurfaces as Sale 257 nears reinstatement

Posted in CCS, energy policy, Gulf of Mexico, Offshore Energy - General, tagged , , on August 7, 2022| 1 Comment »

Tucked into the end of the nearly $370 billion deal struck last week by Senate Majority Leader Chuck Schumer (D-N.Y.) and Senate Energy and Natural Resources Chair Joe Manchin (D-W.Va.) is a requirement for the Interior Department to reinstate a massive 80 million-acre Gulf of Mexico lease sale that a federal judge blocked earlier this year for violating NEPA.

E&E News

Tracts covering 1.7 million acres received bids at Lease Sale 257. 30.5% of those tracts received bids for CCS purposes, leaving about 1.2 million acres receiving bids for oil and gas exploration. Nonetheless, some continue to distort the magnitude of this rather ordinary lease sale. It’s also important to note that the number of active US offshore leases has declined by 72% since 2011, and is now under 2000 for the first time in decades.

If the Schumer-Manchin bill is enacted, what happens to the Sale 257 CCS bids?

Posted in CCS, energy policy, Gulf of Mexico, Offshore Energy - General, tagged , , , , , , on August 2, 2022| Leave a Comment »

The subject legislation requires the Secretary of the Interior to accept the highest valid bid that was received for each tract offered in OCS Lease Sale 257. Exxon was the sole bidder on 94 tracts on the nearshore Texas shelf. The leases were to be acquired for carbon sequestration purposes.

The CCS bids should not be considered valid given that:

  1. Sale 257 was an oil and gas lease sale. The Notice of Sale said nothing about carbon sequestration and did not offer the opportunity to acquire leases for that purpose. Therefore, the public notice requirements for CCS leasing (30 CFR § 556.308) were not fulfilled.
  2. Because there was no draft or final Notice of Sale, interested parties and the public did not have the opportunity to consider and comment on CCS leasing, tract exclusions, bidding parameters, and other factors.
  3. 30 CFR § 556.308 requires publication of a lease form. No CCS lease form was posted or published for comment.
  4. CCS operations were not considered in the environmental assessments conducted prior to the sale.
  5. No evaluation criteria for CCS bids have been published.

Unexpectedly, the Infrastructure Bill, signed on 11/15/2021 (just 2 days before Sale 257) included a provision for OCS carbon sequestration. However, that legislation did not require CCS leasing or authorize DOI to sell CCS leases as part of an oil and gas lease sale; nor did it exempt DOI from complying with its leasing regulations. Instead, It gave the Secretary a year (until 11/15/2022) to promulgate necessary implementing regulations. If carbon sequestration in the Gulf of Mexico is deemed to be desirable, a separate CCS sale should be held when the regulatory framework has been established.

PTTEP joins the CCS parade

Posted in Australia, CCS, well control incidents, tagged , , , , on June 8, 2022| Leave a Comment »

“Our knowledge and expertise in geoscience and petroleum engineering represent advantageous foundation for CCS development, leading us towards our carbon emissions reduction target.” 

PTTEP

Those who closely followed Australia’s Montara Inquiry in 2010 may be less convinced about PTTEP’s expertise. The Montara well suspension program was completely irresponsible. Even though the production casing cement was clearly compromised, PTTEP suspended the well without a single barrier in the well bore. The company was extremely lucky to have avoided a major safety, environmental, and economic disaster. Perhaps they are a very different company now; I certainly hope so.

Montara blowout, Timor Sea

The PTTEP announcement adds to our skepticism about the motives of some CCS proponents. Is CCS prudent public policy? That question is by no means settled and there has been very little opportunity for comment and debate. BOE has raised concerns and there are no doubt many more that have yet to be addressed.

Questions about Gulf of Mexico carbon sequestration

Posted in CCS, climate, energy policy, Gulf of Mexico, pipelines, Regulation, tagged , , , , , , , , on May 12, 2022| Leave a Comment »

Background:

Questions:

  • What are the costs per ton of offshore carbon sequestration including emissions collection, offshore wells and platforms, the associated pipeline infrastructure, ongoing operational and maintenance costs, and decommissioning?
  • What is the timeframe given that the starting point is likely years away?
  • How long would CO2 sequestration continue.
  • Who pays? Polluters? Federal subsidies? Tax credits?
  • Who is liable for:
    • safety and environmental incidents associated with these projects?
    • CO2 that escapes from reservoirs, wells, and pipelines (now and centuries from now)?
    • decommissioning?
    • hurricane preparedness and damage?
  • For Gulf of Mexico sequestration, how much energy would be consumed per ton of CO2 injected? Power source? Emissions?
  • To what extent will these operations interfere with other offshore activities?
  • Relatively speaking, how important is US sequestration given:
  • What are the benefits of offshore sequestration relative to investments in other carbon reduction alternatives?
  • Will BOEM conduct a proper carbon sequestration lease sale with public notice (as required by BOEM regulations) such that all interested parties can bid?
    • What will be the lease terms?
    • Environmental assessment?
    • How will bids be evaluated?
  • What happens to the Exxon bids if the Judge’s Sale 257 decision is reversed?
  • What is the status of the DOI regulations mandated in the legislation with an 11/15/2022 deadline?
    • When will we see an Advanced Notice or Notice of Proposed Rulemaking?
    • Given that DOI has no jurisdiction over the State waters and onshore aspects of these projects, what is the status of parallel regulatory initiatives?
  • Finally and most importantly, how does drilling offshore sequestration wells instead of exploration and development wells increase oil and gas production?

More on the Lease Sale 257 decision

Posted in CCS, Gulf of Mexico, Offshore Energy - General, Offshore Wind, Wind Energy, tagged , , , , on February 2, 2022| Leave a Comment »

The judge correctly dismissed the unfounded claim that new oil and gas leasing would preclude wind development in the Gulf. BOE comments:

  • The number of GoM platforms is down 75% from its peak and continuing to decline.
  • Most new production is in the deepwater GoM and is accomplished with very few, remote and widely dispersed facilities. There are currently only 57 deepwater platforms across the entire Gulf.
  • The wind industry appreciates the synergy between offshore oil and gas and offshore wind operations. Indeed the oil industry has been very supportive of offshore wind, and some of the same operating companies and contractors are major players in both industries.
  • t has been 17 years since the enabling legislation was passed, yet we are still awaiting the first commercial wind project in the US Atlantic. You can’t blame the oil and gas industry for that delay. To the contrary, one can make the case that the presence of oil and gas operations would have accelerated Atlantic wind development.
  • The enabling legislation for offshore wind was drafted by the agency that managed the offshore oil and gas program and recognized the compatibility of oil and wind development. Wind development is clearly a high priority for BOEM, the current OCS land manager.

Will the Administration appeal the court decision to vacate the lease sale or does the decision assist them by reinstating their leasing pause? How will the conflict between the DC court decision and the injunction invalidating the leasing pause (Federal Court for the Western District of Louisiana) be resolved?

What does this mean for the 94 leases that were to have been acquired for carbon sequestration purposes? Will BOEM have a proper CCS sale after conducting an environmental assessment, determining bidding terms and evaluation criteria, and publishing a Notice of Sale? Or will there be a legislative end run that authorizes the issuance of the leases without these steps?
