Specifications : ZNP-1
Technical parameters: Measuring cylinder capacity: 24ml Measuring error: 0.01mm Overall size: 400×180×420
Purpose & characters: ZNP-1 type swelling capacity is mainly used to check and measure swelling change of mud shale in the condition of normal temperature and pressureure, then appraise the rejection characteristic of all kinds of treating compound to mud shale.

Dynamic Linear Swell Meter

Investigating the swelling characteristics of shale formations is vital in selecting a proper drilling fluid to give maximum inhibition and wellbore stability. While drilling a well, a shale formation will immediately begin to swell if the drilling fluid is not completely compatible with the formation. This swelling can cause many problems, such as bit balling, pipe drag, hole sloughing, or other "gumbo" related problems. Therefore, selecting the proper drilling fluid prior to, or during the drilling operation, can be very beneficial in achieving a stable wellbore.

The OFITE Linear Swell Meter is designed to simultaneously test up to four drilling fluids (expandable to eight) on a representative shale sample for extended periods of time at temperatures up to 180°F.

Most swell meters are designed to test shale samples in static fluid. However, fluids circulate as you drill, so testing shale samples in a static environment does not always provide accurate readings.

The OFITE Linear Swell Meter is the only swell meter on the market capable of dynamically testing your fluids, so you obtain the most accurate data possible.
