Drill Stem Testing RD Sampler: Smartstar

The document summarizes a 5" SmartStar fullbore rupture disk sampler tool used for drill stem testing. The tool uses a rupture disk that breaks at a predetermined annulus pressure to allow the sample mandrel to trap a formation fluid sample. Different cartridges allow varying the closing time. After sampling, the tool retains its full-open capability. Multiple samplers can be run to collect samples at different test times. The tool traps 1,200cc of fluid sample in its chamber.

DRILL STEM TESTING

RD SAMPLER

.
5” SmartStar Fullbore Rupture Disk (RD) Sampler.

The SmartStar 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.

Features and Benefits.


• Time-delay feature allows the sample to be
trapped after a preset time. Different metering
cartridges 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.

Operation.
The sampler is controlled by a pressure-operated
rupture disk and has a sample mandrel with a built-
in differential area. To catch a sample, annulus
pressure is increased to a predetermined level, the
rupture disk in the sampler breaks, and the mandrel
traps the sample. When the rupture disk breaks,
the differential area of the sample mandrel is
exposed to an air chamber on one side and
hydrostatic pressure and applied annulus pressure
on the other. This condition results in the sample
mandrel moving up and trapping the sample. When
the sample mandrel reaches the top of its stroke, it
is locked in place by a set of locking dogs. The
1,200-cc sample chamber allows a sufficient
sample for two 500-cc non- monophasic (bulk)
samples.
