Abstract

This report is a summary of a program of comprehensive study, testing, pilot work, and the operational development of a system which reclaims fresh produced water for use as steam generator feedwater. This system is unique because of:

(1) The extremely high quality of the effluent - essentially 0 PPM suspended solids of which oil is the primary contaminant.

(2) The capacity of the system - initial design 200,000 BPD - now increased to 250,000 BPD.

(3) A design which guarantees continuous throughput on a 24-hour basis.

(4) The reclamation which is accomplished at a cost per barrel competitive with other fresh water sources.

The report will discuss the other methods of reclamation tested, the engineering considerations used in the design of the system, and operating problems encountered in the initial operation. The system which has been in operation for three years started at a capacity of 100,000 BPD. It is presently treating in excess of 200,000 BPD and will reach 250,000 BPD by the end of this year.

Introduction

The Getty Oil Company thermal program in the Kern River Field is completely dependent on an adequate and reliable supply of steam generator feedwater. in the summer of 1966, generator feedwater requirements of 100,000 BPD were supplied by eight water wells. This well water was softened and distributed to the field at a company facility called the G and W softening plant. Increasing feedwater requirements, a rapidly dropping water table, and more stringent requirements by the State Water Pollution Control Board on the disposal of field waste water made it apparent that a waste water reclamation system should be investigated. If successful, this system would serve the dual purpose of providing an independent supply for the necessary feedwater requirements and, at the same time, solve the problem of waste water disposal. problem of waste water disposal.
