DEFINITION

Classification: 507/925

COMPLETION OR WORKOVER FLUID:

Subject matter wherein the well treating composition is intended to be used in a generically disclosed workover or completion operation.

(1) Note. A well completion fluid is one generally used in accessing formations which are thought to contain the desired material (i.e., oil) and they allow for the influx of said desired material into the wellbore.

(2) Note. A narrowly suggested workover application (i.e., fracturing, enhanced oil recovery, acidizing, etc.) is not intended for this subclass.
