Abstract

A variety of tests are required in order to determine the quality of water in subsurface injection operations. Water analyses, scaling tendencies, compatibility of mixed waters, residual hydrocarbon content, oxygen content, presence of bacteria, corrosion resulting from the water(s), and the type and quantity of suspended solids must be determined in order to evaluate the water quality for subsurface injection. Most of these tests must be conducted in the field with some additional tests conducted in the laboratory.
