Interest in representative sampling has recently increased due to foreign companies’ activity in the Russian geophysical market. Such issues as sampling in the annular space, nitrogen compensation of the sample taken have become currently important. PJSC NPP VNIIGIS takes measures in cooperation with PJSC TATNEFT to implement a new range of samplers for sampling in the annular space. Requirements for these samplers are the following: maximum downhole tool size is 28 mm, minimum sample volume is 300 ml, maximum length is 2000 mm. Precommissioning is currently underway at some of TATNEFT’s producing wells. This paper presents commercial samplers designed by PJSC NPP VNIIGIS.

Key words:

representative samplers, bubble-point pressure, dew point, single-phase sample
