Watch rare and possibly unique footage of the legendary Pico No. 4 oil well in operation in this 1985 California oil history film produced by the California Department of Conservation’s Division of Oil and Gas. Shot while the well was still actively pumping — five years before its 1990 shutdown — this program preserves moving images of California’s longest continually producing commercial oil well at work in Pico Canyon (Mentryville), in the Santa Clarita Valley.
The film features oil field foreman Frenchy Lagasse explaining and demonstrating the workings of traditional cable-tool drilling equipment in Pico Canyon. Using a detailed model derrick he built himself, Lagasse walks through the mechanics of the walking beam, bull wheel, bailer, jackline systems, and other machinery that defined early California oil production. His segment provides one of the clearest on-camera explanations of how these historic systems operated in Mentryville.

Heart of Heavy Steel: A Mentryville Story by Darryl Manzer, 4-9-2020
>>I have a few items of family memorabilia I've carried around from place to place as I transferred and moved for the Navy and in retirement. This one item, above all, is a memory I can't seem to let go. It was such a happy time when it came into my life, and when it became mine, it was a very sad time.

>>Scofield was a young geologist from the Pennsylvania oil fields who had come to San Francisco to enter the marketing end of this new business. But when he heard of the oil seepage near Newhall, he headed south and acquired acreage in the well-nigh inaccessible Pico Canyon.
[...] It took them a month to drill the first well, C.S.O. No. l (Pico No. 1), to a depth of 120 feet where 11 barrels a day of 32 gravity oil were recovered. But it was abandoned because of the small flow.
C.S.O. No. 2 was the same sort of producer, and it, too, was abandoned. The third hole was dry. A steam engine was brought in and the fourth hole was taken to the prodigious depth of 300 feet. There, on September 26, 1876, 77 years ago next month, C.S.O. No. 4 was completed for 30 barrels a day and a fair amount of gas.
Soon, squat 30-foot wooden derricks sprouted all through the canyons and ridges of the territory.
