In June 1921, which Shell exploratory well discovered Signal Hill?

• A. Pico Canyon
• B. Alamitos Number 1
• C. Long Beach No. 2
• D. Signal Hill Well

Answer: (B)

Pinpointing the exact well that sparked the Signal Hill discovery shows how a single exploratory effort can create a major oil field. In June 1921, Shell drilled Alamitos No. 1 and struck oil at Signal Hill near Long Beach, California. That discovery revealed a sizable, productive oil field in the Los Angeles Basin and set off a rapid wave of drilling and development in Southern California. The other wells listed are either associated with different plays or are not the specific discovery well tied to Signal Hill, so Alamitos No. 1 is the one that marked that milestone.
