Exploration activity declined in offshore California as operators focused on development plans for the nearly 2 billion bbl of oil discovered in recent years. Fourteen planned platforms could more than double current offshore production to 400,000 BOPD. Highlighting the offshore Santa Maria basin was the Reading and Bates Tricia Prospect discovery. The Reading and Bates 1-OCS-P-0416 tested a 1,570-ft Monterey section at a combined initial potential of 2,400 b/d of low-gravity oil. Elsewhere in the basin, successful extension work was recorded in San Miguel and Point Pedernales fields. In the Santa Barbara Channel, exploration activity was highlighted by Union's new-pool discovery in the Santa Clara unit. The Union S-26-OCS-P-0216 flowed 356 b/d of 20.7 oil and 245 MCFGD from lower Repetto sands. Renewed optimism in 1984 increased exploration activity in onshore California basins. 183 wildcats resulted in 51 discoveries: 10 new fields, 7 new pools, and 34 extensions. Most of the success centered in the Sacramento and San Joaquin basins. Drilling in Oregon and Washington reached a near record level in 1984. Activity was quite high in the Mist gas field in Oregon. The 12 wells drilled resulted in 4 new-pool discoveries. The deepest well drilled to date in Washington was abandoned late in the year. The well, drilled in the Columbia basin as a joint venture of Shell and Arco, reportedly reached a total depth of 17,518 ft and tested gas at noncommercial rates. Geothermal activity in California was also at a higher level in 1984, up 32% over 1983. The increase mainly was due to renewed activity in the Imperial Valley gearing up for the installation of 2 new power plants.
