Detachment (CBD) 1058 was formed from "screening Camp Peary and the NCF for geologists, petroleum engineers, oil drillers, tool pushers, roustabouts and roughnecks" and later designated 1058. Additional personnel were chosen for their arctic experience with CBs 12 and 66. They mustered at Camp Lee Stephenson for Operation Pet 4. Congress put $1,000,000 aside to wildcat for oil in U.S. Navy Petroleum Reserve No. 4 (NPR-4) in 1944. NPR-4 had been created and placed in the oil reserve in 1923. Today NPR-4 is the National Petroleum Reserve in Alaska. The detachment's mission was: Do a detailed geologic study at Umiat and Cape Simpson Drill test and core holes Drill a deep well Do complete aerial and overland pipeline surveys for NPR 4. Build a base camp with a runway at Point Barrow Build field camp runways at Umiat and Bettles On July 19 the USS Spica headed north with the S.S. Jonathan Harrington for Point Barrow and Cape Simpson. The det's base camp was constructed at Point Barrow. Four D-8s with twenty sleds of supplies were prepped for the 330-mile trek to Umiat once the tundra had frozen. The first tractor train delivered supplies, the second, heavy well equipment. The D8s would make eight trips total. When summer arrived a wildcat was drilled to 1,816' before the cold shut down operations. The hole was designated Seabee#1 It was near four known seeps at Umiat in the very south-east of NPR 4. The rock strata there was from the Upper Cretaceous and a stratum of it was named the "Seabee Formation". On the coast the Seabees drilled test holes at Cape Simpson and Point Barrow. Once the runways were completed additional supplies were flown in. In March 1946 civilians took over the project. Some Seabees of CBD 1058 were hired immediately upon discharge to continue doing the work they had been doing" The Navy applied the cold weather experience from CBD 1058 for Operation Highjump and Operation Deep Freeze. Seabee #1 remains a USGS monitor well today. Land surveys Twice the Seabees have been tasked with large-scale land surveys. The first was done by CBD 1058 for a proposed NPR 4 pipeline route to Fairbanks. The Trans-Alaskan pipeline follows a portion of their survey from roughly the arctic circle to Fairbanks. The second would be done by a Seabee team from MCB 10. They went to Vietnam in 1956 to survey
