Single phase sampling on the drill string


  • Drill stem testing


  • Able to maintain sample pressure up to 10,000 psi on surface
  • Annular pressure rupture disc activation
  • Can capture 1 or 2 samples with a single tool

The Single Phase Sampler collects a representative reservoir fluid sample, and retains it in a single phase for transfer into transport bottles once recovered to surface. The Sampler is triggered by bursting a precision annular rupture disc. Once the reservoir fluids are collected in the 600cc sample chamber, the nitrogen acts on the fluid to ensure it maintains a single phase. Adding an additional sample chamber to the tool doubles the total sample collected to 1200 cc (2 x 600 cc).
