API Fluid Loss – Water Based Mud Testing

API Fluid Loss - Water Based Mud Testing

The API fluid loss test is used only with Water Based Muds. The test is used to determine the static filtration characteristics of the mud and the need for treatment with fluid loss additives.

Fluid loss must be maintained within the programmed specification to limit potential for differential sticking and formation damage inside the reservoir.

Filter cake thickness is also measured and must never exceed 2 mm.

Filtrate collected during the course of this test is used for subsequent chemical analysis.
