Definitions

  • Embodiments described relate to hydrostatic setting modules for use in downhole environments.
  • equipment and techniques for triggering a hydrostatic setting module are described. More specifically, wireless equipment and techniques may be utilized for such triggering without reliance on potentially more costly or stressful hydraulic triggering modes.
  • the well may be of a fairly sophisticated architecture.
  • the well may be tens of thousands of feet deep, traversing various formation layers, and zonally isolated throughout. That is to say, packers may be intermittently disposed about production tubing which runs through the well so as to isolate various well regions or zones from one another. Thus, production may be extracted from certain zones through the production tubing, but not others.
  • production tubing that terminates adjacent a production region is generally anchored or immobilized in place thereat by a mechanical packer, irrespective of any zonal isolation.
  • a packer such as the noted mechanical packer, may be secured near the terminal end of the production tubing and equipped with a setting mechanism.
  • the setting mechanism may be configured to drive the packer from a lower profile to a radially enlarged profile.
  • the tubing may be advanced within the well and into position with the packer in a reduced or lower profile. Subsequently, the packer may be enlarged to secure the tubing in place adjacent the production region.
  • the mechanism may be equipped with a trigger that is responsive to a given degree of pressure induced within the production tubing. So, for example, surface equipment and pumps adjacent the well head may be employed to induce a pressure differential of between about 3,000 and 4,000 PSI into the well. Depending on the location of the trigger for the setting mechanism, this driving up of pressure may take place through the bore of the production tubing or through the annulus between the tubing and the wall of the well.
  • the noted hydraulic manner of driving up pressure for triggering of the setting mechanism may place significant stress on the production tubing.
  • the strain on the tubing may lead to ballooning.
  • the strain on the tubing may have long term effects. That is to say, even long after setting the packer, strain placed on the tubing during the hydraulic setting of the packer may result in failure, for example, during production operations.
  • the entire production tubing string and packer assembly may be removed, examined, and another deployment of production equipment undertaken. Ultimately, this may eat up a couple of days' time and upwards of $100,000 in expenses.
  • pressurization of the annulus as a means to trigger the setting mechanism requires that the lower, generally open-hole, completions assembly be isolated. Generally this would involve the closing of a formation isolation valve or other barrier valve above the lower completions. Unfortunately, such a valve may not always be present. Once more, such valves come with their own inherent expense, installation cost, and failure modes, not to mention the activation time and techniques which must be dedicated to operation of the valve.
  • a setting mechanism may be employed that is hydraulically wired to the surface.
  • a hydrostatic set module may be utilized that includes a dedicated hydraulic control line run all the way to surface.
  • a dedicated hydraulic line for the setting mechanism only shifts the concerns over hydraulic deployment from potential production tubing stressors, plug placements, or barrier valve issues to issues with other downhole production equipment.
  • a dedicated hydraulic line is itself an added piece of production equipment.
  • a new piece of equipment is introduced, the possibility of defective production string equipment is inherently increased even before a setting application is run. Once more, where such defectiveness results in a failure, the same amount of time and expenses may be lost in removal and re-deployment of the production string.
  • the advantages obtained from protecting the production tubing by utilization of a dedicated hydraulic line for the setting mechanism may be negligible at best.
  • a downhole system includes a hydraulically actuated mechanism along with a hydrostatic set module.
  • the module is hydraulically coupled to the mechanism for its actuation. Additionally, the module is outfitted with a wireless trigger to initiate its own activation to attain the noted actuation of the mechanism.
  • FIG. 1 depicts a front view of an embodiment of a wirelessly triggered hydrostatic set module in conjunction with a packer assembly.
  • Fig. 3 A is an enlarged view of the module and assembly taken from 3-3 of Fig. 2 and revealing wireless pressure pulse communication through the well.
  • Fig. 3B reveals the module and assembly of Fig. 3A with the packer of the assembly set in the well by the module in response to the wireless communication.
  • FIG. 4A is a schematic view of an embodiment of a wirelessly triggered hydrostatic set module and downhole actuatable tool such as a packer assembly.
  • Fig. 4B is a schematic view of the module and assembly of Fig 4B following wireless actuation of the module.
  • Fig. 5 is a schematic view of an alternate embodiment of a wirelessly triggered hydrostatic set module employing redundant wireless triggering.
  • FIG. 6 is a flow-chart summarizing an embodiment of employing a wirelessly triggered hydrostatic set module.
  • Embodiments herein are described with reference to certain downhole setting applications.
  • embodiments depicted herein are of a packer being set downhole as part of a production assembly.
  • a variety of alternate applications utilizing a hydrostatic set module may employ wireless triggering and techniques as detailed herein.
  • wireless is meant to refer to any communication that takes place without the requirement of an optical or electrical wire, hydraulic line, or any other form of hard line substantially dedicated to supporting communications.
  • a downhole system 100 which includes an embodiment of a wirelessly triggered hydrostatic set module 150.
  • the module 150 is provided in conjunction with a packer 175 which may be utilized in sealing and anchoring production tubing 110 at a downhole location (see Fig. 2).
  • the packer 175 is outfitted with sealing elements 177 which may be hydraulically set via a hydraulic line 160 running from the module 150. In alternate embodiments, however, this line 160 may lead to hydraulically set devices other than packers.
  • the module 150 is wireless in nature. As shown in Fig. 1, the module 150 is equipped with a wireless trigger mechanism 130. With added reference to Fig. 2, the trigger 130 is configured to detect a wireless communication from surface 200. The communication may be in the form of a pressure pulse 201 or other signal emanating from surface 201 and transmitted downhole through the well 280. Regardless, the trigger mechanism 130 is configured to actuate the hydrostatic set module 150 in response to the detection of the wireless signal.
  • the trigger mechanism 130 may include a pressure sensor 480 as depicted in Figs. 4A and 4B.
  • a host of different signature types may be utilized in communicating with a processor 470 of the trigger mechanism 130 as described below.
  • a low pressure signature may be most suitable for communications.
  • the trigger mechanism 130 may be equipped with different types of sensors. For example, an acoustic sensor, flow meter or strain gauge may be utilized for respective detection of sonic transmission, fluid flow, or physical tension directed at the system 100 from the oilfield surface 200.

  • the pulse generator may be a pump. In other embodiments, however, alternate forms of wireless signal regulators may be employed as alluded to above.
  • the sealing elements 177 of the packer 175 are shown in an expanded state as directed by the hydrostatic set module 150 in response to actuation by the trigger mechanism 130.
  • the trigger mechanism 130 may be responsive to a wireless signal such as the noted pressure pulses 201, thereby actuating the module 150 until the packer 175 is set. Indeed, as the packer 175 is set, wireless communication with the trigger mechanism 130 are eventually cut off. Of course, this only takes place once the trigger mechanism 130 and module 150 are no longer needed due to the completion of the setting application.
  • the wireless communication signal may be sent through casing annulus as depicted between tubing 110 outside diameter and casing 285 inside diameter or alternately through the bore of the tubing 110 itself.

  • Fig. 3B the system 100 is now shown with the packer 175 set following the above-noted activation of the module 150 by the trigger mechanism 130.

  • This added redundancy may be employed to help ensure that complete triggering and packer setting takes place.
  • wireless communications through the wellbore may face interference challenges such as the presence of air in the case of pressure pulses 201 (see Fig. 2). Nevertheless, the presence of multiple trigger mechanisms 130, 530 increases the likelihood of wireless communication detection.
  • wireless communications may take the form of different signature patterns, independently tailored to each of the mechanisms 130, 530 to further increase the likelihood of processed detection. That is to say, the initial sensor 480 and processor 470 may be tuned to pick up a particular signature of wireless communications for analysis that differs from another signature geared toward the second sensor 580 and processor 575. Thus, where the initial signature fails to fully propagate downhole to its respective sensor 480 and processor 470, the other signature may nevertheless reach the second sensor 580 and processor 575 (or vice versa). Thus, another port 590 may be formed, chamber 530 exposed and the HSM 150 actuated.

  • a downhole system may be deployed into a well.
  • a production tubing system is described.
  • other types of systems may utilize wirelessly triggered hydrostatic set modules, such as completion systems utilizing sliding sleeves.
  • wireless communication signatures such as pressure pulses, may be directed downhole as indicated at 635 and 655.
  • a sensor of a trigger mechanism incorporated into the system may detect downhole communications as indicated at 675.
  • a hydrostatic set module of the system may be triggered by the mechanism based on processing of the wireless detection (see 695). This in turn may result in setting of a packer, shifting of a sliding sleeve or any number of downhole actuations as detailed herein.
  • Embodiments described hereinabove reduce the likelihood of having to remove and re-deploy an entire production string as a result of hydraulic strain induced on tubing due to packer setting. This is achieved in a manner that does not require the presence of a dedicated hydraulic line ran from surface to the hydrostatic set module. As a result, concern over the introduction of new failure modes is eliminated. Furthermore, techniques detailed herein utilize wireless communications in conjunction with a hydrostatic set module that may be employed for a variety of applications beyond packer setting. Therefore, the value of the systems and techniques detailed herein may be appreciated across a variety of different downhole application settings.
