Santa Barbara beach tar reminds us of Platform Holly’s environmental benefits

The cessation of production at Platform Holly 10 years ago has contributed to the periodic surges in natural seepage that soil Santa Barbara area beaches (see the Instagram post above).

The correlation between production at Platform Holly, which lies just offshore from the Univ. of California at Santa Barbara (UCSB), and seepage in the Coal Oil Point area (map below) was apparent to those who worked at Holly. That association was confirmed by UCSB studies:

“Emeritus Professor James Boles collected and analyzed decades of data on methane seeping from the seafloor southeast of Platform Holly, just offshore from Isla Vista. He and colleagues Grant Garven at Tufts University and Chris Peltonen at Beacon West Energy Group determined that production of oil and natural gas from the platform reduced natural methane seepage into the waters of the Santa Barbara Channel, confirming earlier regional studies. The findings appear in the journal Marine and Petroleum Geology.“

This blog called Platform Holly a “net negative hydrocarbon polluter,“ because production from Holly reduced natural seepage and methane pollution from shallow formations beneath the Channel. Steel subsea pyramids (“tents”) installed by Arco in 1982 collected seafloor methane seepage, an added environmental benefit from the platform operations. As described in a 2014 presentation posted by the California State Lands Commission,“production at Platform Holly has resulted in significant improvement in local air quality.”

Further per UCSB:

After combing through 20 years of data, the authors found that production at Platform Holly significantly reduced the amount of methane seeping into the tents. For example, production from a well drilled 1 kilometer beneath the tents immediately reduced the natural seepage. In contrast, the seepage increased when production ceased from that well. “This indicates a direct link between the oil reservoir and the natural seepage in the area,” Boles noted.

Production at Holly ceased 10 years ago; the tents have been removed and the platform is being decommissioned. However, methane bubbles in the Channel and periodic beach tar will continue to remind us of Holly’s positive environmental legacy.

Can Nord Stream AG ‘pig’ the investigation pipeline?

Pictured: pig for cleaning gas pipelines. Will Nord Stream’s suit against the insurers unplug investigation findings?

Nord Stream AG has sued insurers Lloyds and Arch in the English High Court for failing to pay for pipeline damage incurred during the Sept. 2022 Baltic Sea explosions. The estimated pipeline repair costs range from €1.2 to €1.35 billion, and Nord Stream is seeking €400 million from the insurers.

Could this litigation help us learn more about the findings of the official Nord Stream investigations? After 17 months of investigation, Denmark recently concluded that “there are not sufficient grounds to pursue a criminal case in Denmark.” Only nineteen days before Sweden had announced that “Swedish jurisdiction does not apply and that the investigation therefore should be closed.” These weak announcements at the end of lengthy investigations seem too convenient, and may lend credence to Hersh’s Nord Stream account or a recent variation that implicates the UK. Germany is presumably still investigating, and it remains to be seen whether they will release findings.

Could the parties in the Nord Stream case pursue documents or testimony from the Swedish, Danish, or German investigation teams? Both sides in this case, Nord Stream AG and the insurers, would benefit from details that could help identify the responsible parties.

It’s more than a little hypocritical for Western governments and their NGO partners to rail against offshore oil and gas operations while quietly accepting (without investigation) the economic and environmental consequences of the Nord Stream sabotage. Compare the Nord Stream methane emissions with those associated with Gulf of Mexico operations.
