These samplers are run as part the DST string and normally each tool acquires only a single sample. Therefore, to provide redundancy it is necessary to run multiple samplers. Depending on the supplier these, tools can operate by a variety of means, operated by the application of annulus pressure to a rupture disc which in turns activates a porting system which allows fluid to enter into a chamber between the outside diameter and the inside diameter of the tool.
Features and Benefits
1. The operation pressure is certain and steady which controlled by high precise rupture disks.
2. Full-open capabilities are retained after the tool has trapped its sample.
3. Several samplers can be run on a test to allow sampling at different times.
4. A piston pushing device is available, the trapped sample can be transported to other vessels to process PVT analysis under high pressure condition.
5. One time operation, once the RD sampler is closed can not be open again, several samplers can be run on if different testings needed.
