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 downhole.
Features
*The operation pressure is certain and steady which controlled by high precise rupture disks.
*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.
*A piston pushing device is available, the trapped sample can be transported to other vessels to process PVT analysis under high pressure condition.
*One time operation, once the RD sampler is closed can not be open again, several samplers can be run on if different testings needed.
