Rapture Disk RD Sampler

The Rupture Disk (RD) sampler is a full-open, full bore sleeve sampler for use on drill stem tests. The sampler is controlled by a rupture disk that is operated by annulus pressure, used for trapping formation fluid under pressure in the downhole.

Features
Time-delay feature allows the sample to be trapped after a preset time. Different metering cartridge can be used to vary the closing time.
Full-open capabilities are retained after the tool has trapped its sample.
Several samplers can be run on a test to allow sampling at different times.
