(32) The present invention also includes a system 2 for isolating and evaluating, comprising a packer module 3, 4, 5 and an additional packer module 3, 4, 5. Each packer module 3, 4, 5 of
(33) The packer module 10 includes a motor section 20, a conversion section 40, a control section 60, a sealing member 94 and an isolated flow path section 100. The control section 60 includes a ramp sleeve 80 cooperative with the sealing member 94 to set a retracted configuration (
(34) Thus, an additional packer module 10 includes the corresponding components: an additional motor section 20, an additional conversion section 40, an additional control section 60, an additional sealing member 94 and an additional isolated flow path section 100. The additional control section 60 includes an additional ramp sleeve 80 cooperative with the additional sealing member 94 to set an additional retracted configuration (
(35) In the system 2 of the present invention the additional downstream zone of the additional packer module 3 and the upstream zone 96 of the packer module 4 form an isolation middle zone 8. The additional packer module 3 has the same isolation of the corresponding additional downstream zone 98. The additional isolated fluids and the bypass fluids mix back together after the additional packer module 3. In the system 2, the packer module 4 can set the sealing member 94 to cap the additional downstream zone 98. The additional downstream zone of the additional packer module 3 is now also the upstream zone 96 of the packer module 4. This zone capped by the sealing member 94 and the additional sealing member 94 is an isolation middle zone 8.
(36) The system 2 can now evaluate the isolated fluid from the additional downstream zone of the additional packer module 3 AND the resulting mixture of the isolated fluid and the fluid bypass at the packer module 4 AND the fluid bypass before the mixture. The system 2 has multiple checkpoints to confirm analysis and to monitor changes as different isolated fluids mix into the bypass fluid flow. The system 2 can monitor the additions and changes contributed to the bypass fluid flow from each zone. The detecting and measuring instruments in the different flow paths provide the data to the centralized control, which can be in wired connection or wireless connection with the respective instruments. The centralized control is also in communication with packer modules 3, 4, 5 in order to send control signals to the respective motor sections for opening and closing respective isolated flow path inlets of the corresponding packer modules 3, 4, 5. Data from the sensors and meters are used to determine control signals from the centralized control to each module and to characterize the fluids flowing from the different zones. The profile of the wellbore 1 can be more precisely and consistently determined by the system 2 with a packer module 4 and at least one additional packer module 3. Embodiments of the system 2 further include packer modules 5, 9 and others to determine a complete profile of the zones and the contributions from all zones.
(37) The present invention also includes the method of zone evaluation with a packer module 10. The method includes running a packer module 10 in a borehole with the sealing member 94 in the retracted configuration, placing the packer module 10 in a location in the borehole, and transitioning the sealing member 94 in the retracted configuration to the sealing member 94 in the initial sealed configuration so as to form the downstream zone 98 and the upstream zone 96. There is selective control of the step of transitioning as the packer module 10 is controlled to activate the motor section 20. The control section 60 slides relative to the sealing member 94 to press the sealing member 94 to the wellbore for a sealing engagement to the wellbore. The packer module 10 is in communication through a network with other packer modules and a centralized control to coordinate placement along the wellbore.
(38) In the method of the present invention, bypass fluids flow through the motor section bypass flow channels 30, the control section bypass flow channels 70 and the isolated flow path section bypass flow channels 11. The bypass fluids can flow past the sealing member 94 in the packer module 10 and be in fluid connection with the opening 128 of the sensor channel 126. Fluid properties of bypass fluids and isolated fluids from the downstream zone through the opening 128 of the sensor channel are measured. The retracted configuration and the initial sealed configuration of
(39) Embodiments of the method of the present invention further include transitioning the sealing member 94 in the initial sealed position to the sealing member 94 in the isolated sealed configuration of
(40) Additional embodiments of the method of the present invention include running a packer module 4 and an additional packer module 3 in a borehole with the sealing member in the retracted configuration and with the additional sealing member in the additional retracted position. The method of zone evaluation includes using a system 2 of at least two packer modules 3, 4. The additional packer module 3 is also placed in an additional location in the borehole, such as upstream from the packer module 4. The method includes transitioning the sealing member 94 in the retracted configuration to the sealing member 94 in the initial sealed configuration and transitioning the additional sealing member 94 in the additional retracted configuration to the additional sealing member 94 in the additional initial sealed configuration so as to form the additional downstream zone 98 and the additional upstream zone 96. In this embodiment, an isolated middle zone 8 is formed between the sealing member and the additional sealing member by the upstream zone of the packer module 4 and the additional downstream zone of the additional packer module 3.
(41) There is still selective control of the step of transitioning as the packer modules are controlled to activate the respective motor sections. The control sections slide relative to the respective sealing members to press the respective sealing members to the wellbore for sealing engagements to the wellbore at the corresponding locations. The packer modules 3,4 are in communication through a network with other packer modules 3, 4, 5, 9 and a centralized control to coordinate placement along the wellbore. In combination with sensors and meters in the different flow paths to measure rheological properties and environmental conditions, the centralized control collects data for the profile of different flows and commands the packer modules to open and close isolated flow paths. The verification of a fluid profile can be tested and examined by opening and closing isolated flow paths, providing further robustness of the profiled flow through the system.
(42) In this embodiment of the method of the present invention, bypass fluids flow through both sets of the motor section bypass flow channels, the control section bypass flow channels and the isolated flow path section bypass flow channels. The bypass fluids can flow past both sealing members in the packer module 4 and additional packer module 3 and be in fluid connection with the respective openings of the sensor channels. Fluid properties of bypass fluids and isolated fluids from the downstream zones are measured. The retracted configuration and the initial sealed configuration of
(43) Furthermore, the method of using the system to evaluate and isolate can comprise the steps of transitioning the additional sealing member in the additional initial sealed position to the additional sealing member in the additional isolated sealed configuration. Additional isolated fluid flows through the additional isolated flow inlet and the additional outlet end. The additional isolated fluid is measured from the additional isolated flow inlet for the additional downstream zone, now the isolated middle zone 8.
(44) The collected data from the same flow paths now has additional meaning. This zone capped by the sealing member 94 and the additional sealing member 94 is the isolation middle zone 8. The method with the system 2 can now measure the fluids to evaluate the isolated fluid from the additional downstream zone of the additional packer module 3 AND the resulting mixture of the isolated fluid and the fluid bypass at the packer module 4 AND the fluid bypass before mixture. The isolated flow path can be opened and closed to test the accuracy and precision of the data as well. The method of using the system confirms analysis and monitors changes as different isolated fluids mix into the bypass fluid flow.
(45) The system 2 can monitor the additions and changes contributed to the bypass fluid flow from each zone. The profile of the wellbore 1 can be more precisely and consistently determined by the system 2 with a packer module 4 and at least one additional packer module 3. Embodiments of the system 2 further include packer modules 5, 9 and others to determine a complete profile of the zones and the contributions from all zones.
(46) The present invention provides a packer module for isolating and evaluating zones in a wellbore. The packer module includes sealing member to form at least two zones relative to the packer module. The downstream zone can be isolated by the isolated flow path channel. The packer module evaluates bypass fluids through the packer module, isolated fluids from the downstream zone, and mixtures of the bypass fluids and the isolated fluids from the downstream zone. There is selective control of the packer module to change the flow paths through and around the packer module. The motor unit can actuate the sealing member back and forth between the retracted configuration, the initial sealed configuration, and the isolated sealed configuration.
(47) Conventional sensors and measurement devices, like temperature thermometers, pressure gauges, viscosity, and flow speed monitors, along the different flow paths through the packer module gather measurements to profile the fluids passing through the different flow paths, including a fluid bypass flow path. The packer module includes a sensor channel with an opening in fluid communication with bypass fluids and isolated fluids from the downstream zone. One evaluation is the determination of fluid properties across the sealing member of the packer module. Another evaluation is the determination of fluid properties from an isolated zone between packer modules. The contributions and alterations of an isolated zone can be initially determined and tracked through the subsequent bypass flow through another packer module.
(48) The packer module of the present invention is modular and may not always be used to isolate and define a zone. Thus, there is a fluid bypass flow path to allow the packer module to be placed in the middle of a zone, instead of defining a zone. Thus, the isolated fluid flow from a downstream zone formed by the packer module is selectively isolated. Embodiments of the present invention include a packer module having a control section with bypass flow channels and ramp sleeve for selective sealing for isolation of a zone and selective isolated flow from the zone.
(49) The present invention also provides an interactive system of packer modules for isolating and evaluating zones in a wellbore. A system is more than one packer module. The packer modules are interactive and communicate with each other and a central control through wireless or wired connections or both. A packer module and an additional packer module can form an isolated zone between the packer modules for evaluation. The measurement and data from the zone capped by packer modules now disclose fluid properties of the isolated fluid from the additional downstream zone of the additional packer module and the resulting mixture of the isolated fluid and the fluid bypass at the other packer module. The method of using the system confirms analysis and monitors changes as different isolated fluids mix into the bypass fluid flow through the system.
(50) The foregoing disclosure and description of the invention is illustrative and explanatory thereof. Various changes in the details of the illustrated structures, construction and method can be made without departing from the true spirit of the invention.
