Description

CROSS REFERENCE TO RELATED APPLICATIONS This is a Continuation-In-Part Application of U.S. application Ser. No. 19/221,203, filed May 28, 2025, which is a Continuation Application of U.S. application Ser. No. 18/540,728, filed Dec. 14, 2023, the entire disclosures of which are incorporated herein by reference. BACKGROUND During oil and gas exploration, many types of information may be collected and analyzed. The information may be used to determine the quantity and quality of hydrocarbons in a reservoir and to develop or modify strategies for hydrocarbon production. For instance, the information may be used for reservoir evaluation, flow assurance, reservoir stimulation, facility enhancement, production enhancement strategies, and reserve estimation. One technique for collecting relevant information involves obtaining and analyzing fluid samples from a reservoir of interest. There are a variety of different tools that may be used to obtain the fluid sample. A downhole fluid and sampling tool can be used to acquire at least one downhole fluid sample, for example. The downhole fluid sample may then be analyzed in a laboratory to determine fluid properties. When several downhole fluid samples are desired, electrically or hydraulically actuated valves are required to provide isolation of each fluid sample in a vessel. An electrically or hydraulically actuated valve is dedicated to each fluid sample vessel. However, when large quantities of downhole samples are needed, the number of electrically or hydraulically actuated valves the downhole fluid and sampling tool can handle becomes a limiting factor.

DETAILED DESCRIPTION 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. The volume of the downhole fluid sample can be from about 0.1 mL to about 500 mL, or anything in between, or from about 0.1 mL to about 100 mL, or from about 0.5 mL to about 75 mL, or from about 1 mL to about 50 mL, or from about 2.5 mL to about 25 mL, or from about 5 mL to about 20 mL, or from about 10 mL to about 15 mL, or from about 1 mL to about 10 mL, or from about 1 mL to about 5 mL, for example. In embodiments, hydraulic pressure is created by an electric motor-driven hydraulic pump. It is then communicated via solenoid valves to designated lines. An algorithm then elevates and relieves pressure on the primary bus, then elevates and relieves pressure on the secondary bus, then repeats itself until all valves have received power. The sample containing vessel itself is a rod with annular cutout in which the fluid may be isolated when positioned into a bore that also serves as a cartridge for handling on the surface. This allows a small set of directly controlled actuators to indirectly actuate any arbitrarily larger set of valves, and therefore, to isolate a larger set of downhole fluid sample vessels without any
