SEGREGATION CHAMBER FOR DOWNHOLE FLUID RETENTION AND TESTING

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of Chinese Patent Application No.

202311776221 .3 filed December 21 , 2023.

FIELD OF THE DISCLOSURE

[0002] Aspects of the disclosure relate to obtaining fluid samples and testing those samples from a downhole environment. More specifically, aspects of the disclosure relate to a segregation chamber for downhole fluid retention and testing that allows sampling hydrocarbons to be segregated from water-based mud filtrate and other materials.

BACKGROUND

[0003] When sampling hydrocarbons (HC) from a reservoir with a formation tester, it can be difficult to separate the invaded mud filtrate from the native reservoir fluids. Focused sampling techniques exist to help speed up this clean up, but focused sampling only works when native fluids flow in sufficient quantities to separate the native fluid from the filtrate.

[0004] Particularly in water-based mud (WBM) environments and in reservoirs with deep invasion or transition zones, where native HC flow in small quantities, there is a need for a structure to help the segregation of fluids. There is a need for a structure where a mixture of HC and WBM filtrate can be pumped, to allow sampled hydrocarbons to float to the top and WBM filtrates to sink down.

[0005] There is a need to provide apparatus and methods that are easy to operate and provide a separation capability.

[0006] There is a further need to provide apparatus and methods that do not have the drawbacks discussed above, namely sample chambers that allow for the mixing of hydrocarbons and water-based mud materials. [0007] There is a still further need to reduce economic costs associated with operations and apparatus, described above, with conventional tools for sampling of downhole hydrocarbons.

Instead, any combination of the following features and elements, whether related to different embodiments or not, is contemplated to implement and practice the disclosure. Furthermore, although embodiments of the disclosure may achieve advantages over other possible solutions and/or over the prior art, whether or not a particular advantage is achieved by a given embodiment is not limiting of the disclosure. Thus, the following aspects, features, embodiments and advantages are merely illustrative and are not considered elements or limitations of the claims except where explicitly recited in a claim. Likewise, reference to “the disclosure” shall not be construed as a generalization of inventive subject matter disclosed herein and should not be considered to be an element or limitation of the claims except where explicitly recited in a claim.

[0027] Although the terms first, second, third, etc., may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, components, region, layer or section from another region, layer or section. Terms such as “first”, “second” and other numerical terms, when used herein, do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed herein could be termed a second element, component, region, layer or section without departing from the teachings of the example embodiments. [0028] When an element or layer is referred to as being “on,” “engaged to,” “connected to,” or “coupled to” another element or layer, it may be directly on, engaged, connected, coupled to the other element or layer, or interleaving elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly engaged to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no interleaving elements or layers present. Other words used to describe the relationship between elements should be interpreted in a like fashion. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed terms.

[0029] Some embodiments will be described with reference to the figures. Like elements in the various figures will be referenced with like numbers for consistency. In the following description, numerous details are set forth to provide an understanding of various embodiments and/or features. It will be understood, however, by those skilled in the art, that some embodiments may be practiced without many of these details, and that numerous variations or modifications from the described embodiments are possible.

For definitional purposes, a non-volatile memory system may be a memory system that does not wipe clean after termination of electrical power to the system. Examples of non-volatile memory systems may be compact disks, solid-state drives, and universal serial bus devices. These memory systems may be used to store program executable method steps for a computer, server, or computing arrangement.

[0031] Embodiments of the disclosure describe hardware and workflows for a continuous segregation chamber, where HC and WBM filtrate are continuously pumped through a formation tester segregation chamber and where the lighter HC phase is allowed to segregate into the chamber, while the heavier WBM filtrate phase is removed from the chamber until the segregation chamber is filled with (mainly) HC. Once sufficient HC has accumulated in the chamber, it can either be diverted to smaller PVT bottles, or the full chamber can be sealed and retrieved to the surface with the formation tester toolstring.

[0032] Several different tool configurations and workflows are presented. Aspects of the disclosure are written with the objective of capturing HC in a WBM environment, but the technique can be used for any two (or more) phase flow scenarios.

[0033] In one embodiment of the disclosure, a formation testing platform with a large volume chamber is used. The chamber can be configured as either a 5, 10, or 25 L chamber with four active seal valves and several surface configurable valves as nonlimiting embodiments. This flexibility allows the chamber to have several different functions. For example, the chamber can be filled with clean water to inflate a radial probe or dual packer, or to inject fluid into a fracture. Alternatively, the chamber can be used to capture samples or used as a segregation chamber. In some configurations, a combination of some or all of the functions is possible. Aspects of the disclosure describe the hardware and workflow to use components as a continuous segregation chamber.

[0034] Several different segregation chamber configurations and workflows are described in this section.

Terminology:

FNFM - pump

FSCM - Multi sampling module with six pressure volume temperature bottles

FISO - Fluid analysis module

FLVC - Large volume chamber

FCRF - Focused radial probe FCII - Dual-packer module

Configuration A: FLVC as a continuous segregation chamber - focused sampling

[0035] FIG. 1 illustrates a schematic for the use of a continuous segregation chamber during focused sampling with a FCRF. In this configuration, a HC-filtrate mixture from the FCRF sample line inlet 102 is pumped on line 104 and directed into the segregation chamber 100. Once the chamber 100 is full, the heavier phase (filtrate) will be forced through chamber valve 2 106 which is routed back to line 104, above the closed flowline 1 valve 108. Monitoring line 1 111 with FISO shows pure filtrate on line 104 when the continuous segregation chamber 100 is segregating out the HC. Once the segregation chamber 100 is filled with HC, the FISO will start showing a mixture of HC & filtrate again. At this time, the FLVC chamber valves 110 can be closed and the HC sample is captured.

[0036] Note that in this scenario the water line 140 is routed to line 113, below the flowline valve for the guard line 113.. The water line 140 will be at borehole pressure and the FLVC filling is driven by the line 130 FNFM. Chamber valve 106 can be optionally kept closed until the chamber 100 is full. Once full, the chamber valve 106 can be opened to start the continuous segregation process (requiting flow through the chamber).

[0037] Note that variations in sequences are possible, such as closing the FSCM sample valve instead of the FLVC line 1 valve.

[0038] Once the FLVC contains sufficient HC, the chamber 100 can be sealed. It may be preferred; however, to divert the segregated HC into FSCM PVT bottle 150 so that the FLVC may be re-used as a segregation chamber, or filled with filtrate, to be used on a subsequent station as a source fluid to set the FCRF.

[0039] To divert the FLVC HC into an FSCM PVT bottle 150, the valve positions are changed to the positions indicated in FIG. 2. The lower FNFM 130 is now used to pump fluid up the line into the FLVC water line, forcing the piston down and pushing the captured HC through chamber valve 106, into line 104. In embodiments, the FISO 165 is used to monitor the time that pure segregated HC is observed and at this time the FSCM bottle 150 is opened, and a sample is captured.

Configuration B: FLVC as a continuous segregation chamber - focused sampling using line 2 as exit port

[0040] A second configuration of the disclosure is presented in FIG. 3. FIG. 3 shows the schematic for use of the continuous segregation chamber during focused sampling with an FCRF. A HC-filtrate mixture from the FCRF sample line inlet 202 is pumped to line 204 and directed into the segregation chamber 200. Once the chamber 200 is full (or earlier) chamber valve 206 is opened, and the heavier phase WBM filtrate will be forced from chamber valve 206 to flowline 208, where it will mix with the guard fluid 210 that is already being pumped on line 212. Monitoring line 214 with FISO shows pure filtrate flowing when the continuous segregation chamber 200 is segregating out the HC. Once the segregation chamber is filled with HC, FISO shows a mixture of HC & filtrate on line 212 again. At this time, the FLVC chamber valves 206 can be closed and the HC sample is captured. Note that the segregation chamber flow direction can also be changed with fluid entering on line 212 (chamber valve 2 206) and exiting on line 208 (chamber valve 206). This would require the flowline valve positions to be reversed.

[0041] Once the FLVC contains sufficient HC, the chamber 200 can either be sealed or diverted to the segregated HC into FSCM PVT bottle 220 so that the FLVC may be reused as a segregation chamber, or filled with filtrate, to be used on a subsequent station as a source fluid used to set the FCRF.

[0042] To divert the FLVC HC into an FSCM PVT bottle 220, fluid will be drawn, as indicated in FIG. 4, down line 224, through the FCRF comingle valve 175, up line 1 to the FSCM bottle 220. The FCRF interval valves will be closed and the comingle valve open 175 . The FLVC line 1 240 valve is open, and line 2 valve 242 is closed. Note that either the upper FSCM can be used in up mode or the lower FSCM is used in down mode. In case there is some WBM filtrate in the FLVC, this would flow from the FLVC first. FISO line 1 250 would be monitored to detect the transition from WBM filtrate to HC, after which flushing and sampling can commence. Configuration C: FLVC as a continuous segregation chamber - unfocused sampling [0043] A third configuration for a continuous segregation chamber is illustrated in FIGS. 5A and 5B. FIG. 5B shows how fluid is flowing from the FCRF sample line 502 and is pushed into the FLVC on line 1 504 with the lower FNFM configured with a routing plug. On line 2 506 fluid is pulled from the FLVC by the upper FNFM 508 configured with a X- routing plug. In this case the chamber is, e.g. 5 L. The FLVC can either be filled initially, followed a second step where the rate into the chamber with the HC-filtrate mixture is the same as the rate out, or alternatively, the rate into the chamber can be higher than the rate out of the chamber. The difference in rate should be close to the expected HC-cut, so that the volume added to the chamber is mainly HC. The fluid flowing on line 2 is monitored with FISO, confirming that no gas is flowing from the chamber.

[0044] FIG. 5A shows a similar set up 500, but with a different FLVC configuration that allows comingled sampling during use of the continuous segregation chamber.

[0045] Once the segregation chamber contains sufficient HC, the chamber can either be closed and the sampled HC is secured, or the captured HC can be diverted to one or more smaller (PVT) bottles in the upper FSCM shown in FIGS. 6A and 6B.

[0046] Note that if any WBM filtrate remains in the bottle, this can be pumped from the FLVC with the lower FNFM after changing the operating mode from pump-up to pumpdown, or with the upper FNFM on line 2. In this configuration, using line 2 has the advantage that flow is directed upwards through the FISO for detection.

[0047] Next, the segregated gas is pulled from the FLVC by the upper FNFM on line 2 and directed to the upper FSCM where it can be captured using regular drive sampling techniques.

[0048] Alternatively, the HC from the segregation chamber can be diverted to an FSCM PVT bottle by pressurizing the FLVC and diverting the HC to an FSCM bottle under its own pressure. The advantage of the scenario is that the HC can be sampled on line 1 and no additional FSCM required. [0049] Referring to FIG. 7, line 1 702 shows the path from the FLVC 704 to the FSCM sample bottle 706. If sufficient pressure is applied to the FLVC 704 during filling, the HC can flow from the FLVC 704 to the FSCM 706 under its “own” pressure.

[0050] However, this method is not preferred because the heavier phase will always be forced from the segregation chamber first, and every time the chamber is re-pressurized by the pump, new filtrate will likely enter the chamber.

[0051] In embodiments, certain parameters may be changed or altered. This may include, but not be limited to the following:

1. Other inlets, or combinations of inlets, can be used. For example, the focused radial probe could be changed to a focused single probe or a single-inlet or dualinlet dual-packer.

2. The position of the FISO module can change.

3. Continuous flowline segregation can start either with the FLVC already filled with a fluid, or with the FLVC empty.

4. In configurations above, the chamber can be pre-filled with water from the surface or filled with fluid from a previous station, and this chamber fluid can be used to inflate the probe, radial probe, or dual-packer on a subsequent station.

5. FNFMs can be surface configured with different routing plugs.

6. FSCM sample bottle carrier positions can be changed.

7. Sample down configurations are also possible with continuous segregation indicated in FIG. 8A and subsequent HC diversion to an FSCM bottle in FIG. 8B. FIG. 8B is a mirrored image of FIG. 8A.

[0052] Referring to FIG. 9, a non-limiting method 900 for performing sampling with a downhole tool is presented. The method 900 may comprise, at 902, lowering a sampling tool into a wellbore in a geological stratum. The method may further comprise, at 904, actuating a pump within the sampling tool to draw a volume of fluid from the geological stratum. The method may further comprise, at 906, transporting the volume of fluid to a segregation chamber within the sampling tool.
