Figure 3. Aerial photograph of Long Beach/Los Angeles Harbor showing the location of the three horizontal-well projects. North is to the top. On the left (west) is the steamflood project (case history 1) with four horizontal wells placed in the Tar zone below Terminal Island. The location of cross section A-B is shown. Case history 2 consists of five horizontal wells that cross under the Los Angeles River channel and are part of a Tar zone steamflood project in Fault Block V (FB V). The location of cross section CD is shown. Case history 3 involves a tight-radius horizontal well that lies stratigraphically below case history 2 in Fault Block V in the upper Terminal zone. Oil activities coexist with the busiest harbor in the country, and the Fault Block V steamflood is below Long Beach’s new $180 million aquarium.
