A method of programmed data acquisition is presented to help non-specialist engineers monitor water quality. Field tests, sample collection, laboratory procedures and methods of data presentation are standardized. Specifically, a series of profile plots are prepared from which engineers "read-out" pertinent features of plant performance and water quality. The direct "read-out" procedure, after nominal practice, is relatively simple. In many respects, it may be compared with qualitative log interpretation.

A manual for using the Standard Data Package is also presented. Included are "rules of thumb" and other empirically derived "yardsticks" covering several important parameters.


The increasing importance of salt water handling, either in disposal or waterflood operations, has demanded development of better methods. A full understanding of basic parameters is fundamental to creating the best plant design and to determining the most effective operating practices. Toward this end various methods have been proposed to define "water quality", diagnose problems, predict potential problems and ultimately, to use these technical method to maximize operating efficiency.

It is a major purpose of this paper to present a standardized method of programmed data acquisition that lends itself to direct measurement of water quality by non-specialist engineers. The heart of the program is the collection and preparation of a "Standard Data Package". While involving a comprehensive technical investigation, the interpretation process is simplified so that unusual technical skills are not often required.

Specifically, a standardized format is proposed whereby engineers can inspect a series of charts and "read-out" pertinent features of an injection system's performance. While the "read-out" process appears quite simple, the individual is in effect solving partial chemical material balance calculations that logically lead to sound engineering conclusions.

The standardized plan is readily adaptable to regular surveillance of water systems. After an initial comprehensive study, data acquisition can be programmed in advance so that attention is focused on an operation at regular intervals. Comparison of standard charts of succeeding studies is done by inspection. Likewise, with all procedures standardized, results between studies of different projects can be directly compared.


The proposed plan of water quality control can be illustrated by noting the physical similarity of water injection systems and chemical manufacturing plants. Both convert raw material to finished products. Either may be simple or highly complex. Systematic collection of basic in-put and out-put data is recognized as a requirement for efficient operation of a manufacturing plant.
