Well testing Rupture disk RD sampler
drill stem testing rupture disk sampler for Well testing service
Introduction of DST RD sampler
The sampler is controlled by a rupture disk that is operated by annulus pressure, used for trapping formation fluid under pressure in downhole.
Features and Benefits
l The operation pressure is certain and steady which controlled by high precise rupture disks.
l Full-open capabilities are retained after the tool has trapped its sample.
l Several samplers can be run on
l A test to allow sampling at different times.
l A piston pushing device is available, the trapped sample can be transported to other vessels to process PVT analysis under high pressure condition.
l One time operation, once the RD sampler is closed can not be open again, several samplers can be run on if different testings needed.
