To date, utility company underground storage of gas has generally beenrestricted to depleted dry gas fields. The Playa del Rey project is probablythe first to successfully store gas in a partially depleted oil reservoir withthe recovery of large volumes of gas at high rates as the main objective. Oilrecovery has been a secondary consideration.
Problems encountered unusual to those of storage in a dry gas zone were: (1)the removal and retardation of formation of emulsion, (2) the up structuremovement of fluid during withdrawal periods which formed fluid blocks, and (3)reservoir shrinkage resulting from encroachment of edgewater.
The solution of these problems as outlined in the paper has resulted inincreasing the withdrawal rate from the original design capacity of 4,000 Mcfper hour to the current 10,000 Mcf per hour. Additional increase is anticipatedas the operations continue.
Migration, reservoir performance, operational procedure and a historicalrecord are included to make this a resume of the project from its war-timeinception in 1942 to the first of 1952.
The Playa del Rey underground gas storage project is probably the firstproject in which gas has been stored in a partially depleted oil reservoir,with the recovery of large volumes of gas at high rates as the main objectiveand the recovery of oil a secondary consideration. Problems unusual to those ofstorage in dry gas zones have made this a pioneer endeavor.
The total storage capacity of approximately 1,500,000 Mcf of this reservoiris small in comparison with other underground gas storage projects. However, bystudy and experiment the deliverability into transmission lines, operating atpressures in excess of 150 lbs., has been nearly tripled in the past threeyears to the current 10,000 Mcf per hour rate, without the life of compression.It is anticipated this rate will gradually increase as additional fluid isremoved from the formation.
Location and History
Playa del Rey is located on Santa Monica Bay about two miles south of thebeach community of Venice and 15 miles southwest of the center of the City ofLos Angeles. Fig. 1.
