Brief Introduction
The rupture disk 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.


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 nonmonophasic (bulk) samples.

1. Halliburton type, all could change with Halliburton parts.
2. All equipments are produced according to API standard NACE MRO175-2002
