JL Daeschler and George HW Bush
Posted in drilling, Offshore Energy - General, Uncategorized, tagged George HW Bush, JL Daeschler, Zapata on July 29, 2023| Leave a Comment »

Jean-Louis Daeschler, a pioneering offshore engineer, has shared this very interesting story about his interaction with George HW Bush (pictured):
One day I was driving in Kennebunkport and told my wife that I met the man who lived in that house on the coastal road – the President George HW Bush!
Early in my career, a new drillship was being built in Port Arthur TX for Zapata Offshore. One morning, the entrance to the shipyard was closed off. A peaceful group of picketers told us we could not enter. Many of us had left work clothes, file drawings, and even passports and money at our camp in the yard. This was before mobile phones and the internet! So we went back home to wait for guidance. 2-3 days later we had to attend a meeting in Houston (a 2 hr drive) at the Pennzoil Tower, and we met Mr Bush. He was very cool and calmed us down. He advised us not to cross the picket line or get into an argument with the workers. He had already made arrangements to use 4-5 rooms at a Holiday Inn near Beaumont. They removed the hotel furniture and provided desks, pencils, and phones. Our personal effects had been collected from the yard and delivered to the our temporary workplace at the Holiday Inn.
My colleagues and I had a great chat with Mr. Bush. In particular he asked me questions about the D-Day invasion at Normandy. However, although I was born there, it was at the end of the war in 1945, so I did not personally experience the invasion. We left the meeting relaxed and with directives on what not to do. He kindly gave me one of his gold Cross pens, before we shook hands and departed.
Years later at a dinner in Aberdeen with Total Fina Elf, I gave that pen to the wife of the Project Manager (without the story). So there we go; a pen from Houston goes to Paris via Aberdeen in 17 years! Sometimes you smile in the oil patch!

Ironically, the ultimate clean energy source is dependent on drilling technology
Posted in drilling, energy, tagged Carlos Araque, drilling technology, Quaise Energy, ultradeep geothermal on July 5, 2023| Leave a Comment »
Because space requirements and intermittency limit the ultimate potential of other renewable energy super-sources, ultradeep geothermal may be the most exciting energy alternative on the horizon. However, ultradeep geothermal’s enormous potential can only be achieved if we can reliably drill deep beneath the surface and tap into superheated rock. As Quaise Energy’s Carlos Araque, formerly a Schlumberger engineer, has noted: “A lot of the challenges are the same as for oil and gas.”
This short video provides a good summary of the drilling technology that is under development.
Ultradeep geothermal is the most exciting renewable energy alternative

Linking an excellent article on a renewable energy alternative that BOE has been following closely.
Good assessment:
I’m confident because the externalities that come with wind, solar and batteries, which are the other top candidates, are too large to bear at multi-terawatt scale: too much land, too many minerals, too much labour per unit of energy. Geothermal is very different: it is more like fossil fuels without the carbon. It’s more like nuclear – except fusion doesn’t work yet and fission is controversial.
Carlos Araque
Challenges:
A lot of the challenges are the same as for oil and gas. The subsurface is an uncertain environment. The deeper you go, the more extremes you have, but we’ve come a long way with the oil and gas industry to develop a whole suite of technologies, techniques and measurement systems to minimise that risk. The main challenge is maintaining wellbores from closing in on themselves as you go deeper. There’s a lot of pressure in the rock and these holes eventually will collapse. The way we answer that is by creating a glass wall in the rock as we burn it. When our technology vaporises the rock, it creates a glass wall and that remains on the walls and prevents the hole from collapsing.

150th Gulf of Mexico well in >8000′ of water as rig count remains strong

Per the BSEE borehole file, there were 2 deepwater exploratory well starts since 4/1/2023. The Shell well is another GoM milestone in that it is the 150th well spudded in >8000′ of water. The first was in the year 2000.

Based on drilling contractor rig activity reports, the table below lists 19 deepwater MODUs under or soon to begin contracts in the GoM. (Further details are pasted at the end of this post.) Per the Valeris report, platform rigs are operating on bp’s Thunder Horse and Mad Dog platforms. Per the BSEE borehole file, Arena and Cantium continue to drill development wells on the GoM shelf.

Sharing this touching tribute to the 11 men who died on the Deepwater Horizon on April 20, 2010. These American heroes gave their lives exploring for energy to power our economy. The video is introduced by singer Trace Atkins, a former Gulf of Mexico rig worker. Please take a moment to watch.
2022 & Q1 2023 GoM well starts, plus a possible explanation for BP’s reduced bid for Green Canyon 777

- Deepwater (>1000′) activity continues to dominate, accounting for 61% of the well starts.
- Not a single company drilled both shelf and deepwater wells.
- While shelf facilities currently account for only about 7% of GoM oil production, 1122 of the 1179 remaining platforms are on the shelf and they account for 24% of GoM gas production, most of which is environmentally favorable nonassociated gas.
- Two companies, Arena and Cantium, accounted for 75% of the shelf well starts. Excluding the CCS bids, Arena and Cantium were the most active shelf bidders in Sale 279. Arena bid alone on 7 blocks. Cantium was the high bidder on 5 blocks. (Focus Exploration was high bidder on 4 shelf blocks and was “outbid” by Exxon for High Island 177.)
- One company, Shell, accounted for 39% of the deepwater well starts
- One of BP’s exploratory wells (drilled subsequent to Sale 257) was in Green Canyon 821, immediately south of GC 777, the block that BP/Talos bid $1.8 million for in Sale 257. That bid was rejected by BOEM. In sale 259, BP was the sole bidder for GC 777, and their bid was only $583,000, less than 1/3 of their Sale 257 bid. Perhaps the GC 821 exploratory well reduced the value of GC 777? Will this lower bid now be accepted?
