Abstract
Disclosed herein are methods and systems for capturing a large collection of downhole fluid samples and, more particularly, disclosed are methods and systems for using at least two hydraulic pressure lines to alternatingly actuate hydraulic valves disposed in an interlinked series to obtain any large collection of hydraulically actuated components to be energized in sequence. A large collection of downhole fluid samples may be defined as any number of downhole fluid samples wherein the number of downhole fluid samples is larger than the number of actuators.
Claims20
A system comprising a fluid sampling tool comprising:
- at least one probe in fluid communication with a formation;
- at least one passageway that passes through the at least one probe and into the fluid sampling tool;
- and
- at least one fluid sampling vessel, wherein the at least one fluid sampling vessel comprises at least one removable cartridge in fluid communication with the at least one probe through the at least one passageway, wherein the removable cartridge comprises a sliding sleeve, a sample cavity for fluid storage, and a cartridge flow line.
A method comprising:
- disposing a fluid sampling tool in a wellbore;
- establishing fluid communication between a formation and the fluid sampling tool through a fluid passageway;
- establishing fluid communication between the fluid passageway and a fluid sampling vessel, wherein the fluid sampling vessel comprises at least one removable cartridge in fluid communication with the fluid passageway, wherein the removable cartridge comprises a sliding sleeve, a sample cavity for fluid storage, and a cartridge flow line;
- and
- sliding the sliding sleeve to isolate the sample cavity from the fluid passageway.
