  • ZND, a special gel has recently found a wide use in controlling mud losses. This paper discusses a novel instrument used for the evaluation of ZND, and a method of measuring the start-up pressure of ZND-liquid level-pressure curve method. By plotting the liquid level versus pressure, this high-precision instrument can be used to determine the start-up pressure of ZND in simulated formation conditions, and the performance of gels at the same start-up pressure.
