RD Sampler APR Drill Stem Testing Tools High Pressure Rupture Disk Sampler
RD Sampler introduction
The RD sampler is a part of DST tool string, the rupture disk of the sampler is controlled by the annulas pressure, the RD sampler is used for trapping formation fluid under pressure in downhole testing service. The 1,200-cc sample chamber allows a sufficient sample for two 500-cc non- monophasic (bulk) samples.
Application of RD sampler
* The sampler is used to catch the sample during the DST operation in cased hole.
* For the 3 7/8" RD sampler is applied for the slim hole downhole testing to trap the fluid sample
* The RD sampler is applicable for the high pressure and high temperature working condition
* The RD sampler made of Inconnel material is used in Full H2S service in downhole testing.

How to confirm the rupture disk of the sampler?
In order to select the proper rupture disk should know:
* Downhole temperature
Before to use the RD sampler, we must to know the downhole temperature in the oil well, then to select the correct rupture disk.
* Hydrostatic pressure
* The max. operation pressure of other tools which also operated by annulus pressure
Each approved rupture disk has pressure-temperature curve which get from actual testing in the same lot under temperature 100-150F, the tolerance is within 3%. The temperature and average burst pressure will be stamped in the rupture disk, so according to the pressure-temperature curve can get the burst pressure with downhole temperature.
Drill stem testing tools for cased hole, open hole and slim hole:
* Full bore retrievable packer: RTTS packer, mechanical setting retrievable packer, Double grip mechanical setting retrievable packer, Single grip mechanical setting retrevable packer, CHAMP packer, High pressure retrievable packer, high pressure retrievable packer with bypass
* Downhole Tester Valve: Select tester valve, LPR N Tester valve, tubing string test valve
* Circulating valve: full bore retrievable circulating valve, multi-cycle circulating valve, omni valve, RD safety circulating valve, IPO valve, RTTS Circulaitng valve, Hydraulic circulating valve
* Shock Absorber: Vertical shock absorber, Radial shock absorber
* Safety valve: RTTS safety valve, Super Safety valve, BOP safety valve
