Definitions

  • the present invention relates to monitoring subterranean formations and more particularly, systems and methods for monitoring a parameter of a subterranean formation using swellable materials.
  • Challenges with downhole measurements may include securely coupling sensor packages to the rock mass, isolating the packages as much as possible from noise in the wellbore, and providing cabling paths (if necessary) for transmitting data to the surface.
  • Sensors may be deployed permanently or retrievably.
  • Retrievable sensors packages are often deployed on wirelines, but also on coiled tubing or production tubing.
  • Wireline deployed arrays may use clamp arms, magnets, or bow springs for coupling to the wellbore, whereas coiled tubing or tubing deployed arrays may have decentralizers and may be locked into the wellbore through friction and bending stresses.
  • these types of deployment may be susceptible to coupling problems if the clamp arms do not fully extend, if magnets are placed over scale or other wellbore irregularities, or if the coiled tubing is not wedged against the casing wall.
  • Permanent sensors may be cemented in place, but this can be a difficult and costly process for sizable sensor arrays.
  • Successful deployments of large sensor arrays may have inserted the sensors coupled to tubing inside cemented casing with the tubing then cemented inside the casing. Attempts to directly place sensor arrays on the outside of casing have often been unsuccessful due to damage to the array during emplacement.
  • a successful deployment of cemented sensors may remain susceptible to noise transferred either up or down the tubulars because of the affixation to the tubing or casing.

  • sensors may be at least partially emplaced within swell packers for direct coupling to tubulars with maximum isolation from the rock mass for cases where it is desirable to monitor the tubing deformation and/or flow noise/activity within the tubing.
  • swell packers may be constructed of elastomers that swell when exposed to either hydrocarbons or water, depending upon the application, in order to seal off and isolate zones within the wellbore.
  • the swell packers may provide coupling by swelling and forcing a sensor package against either a formation, a wellbore, or any rigid contact point.

  • one or both of the valve 570 and the slide 576 may be adapted so the ports of the slide may be selectively aligned with the ports of a reservoir by rotation, rather than lateral motion of the slide 576 indicated in FIG. 5H .
  • the slide 576 may have a disk form with ports that may be rotated about a center.
  • FIG. 5J illustrates a mandrel 525 A that may be used in the alternative or in addition to expansion sleeves to couple two or more adjacent circular components 510 A and 515 A.
  • the mandrel 525 A may be used as a one- or two-ended piston to prevent or minimize lateral expansion such that expansion is directed along an axis of the mandrel.
  • secondary mandrels in the outer arrangement 515 may be preferred in order to shift the centerpoint of the inner arrangement 510 as the tubular body 505 may not always be well-centered in the borehole 540 .
  • a mandrel 525 A may include an outer body 525 B that at least partially surrounds an elastomer material 525 C.
  • the elastomer material 525 C is shown in an at least partially expanded state.
  • the outer body 525 B may comprise metal, a composite, or any other suitable material.
  • the system 500 allows sensor packages to be deployed in a state that has no direct physical contact or intermediate structural contact with the tubular body. Having the tool placed against the side of the borehole with no direct solid-to-solid contact with the tubular body, the sensor packages are afforded a degree of acoustic isolation from acoustics that may otherwise be transferred via the tubular body. Further, the system 500 provides a safety margin such that the tool may be spared from sharp, high-force, or uncontrolled movements that could endanger tubing, wiring, the borehole wall, or the tool.
  • the generally circular outer arrangement 515 provides a perimeter that may allow for positioning while maintaining tolerance for irregularities that may be encountered in the surface of the borehole. Although system 500 is depicted with four circular components and four sensor packages in the outer arrangement 515 , and four circular components in the inner arrangement 510 , it should be understood that other embodiments may include a different number and combination of circular components and sensor packages.
  • the inner arrangement 510 may be coupled to spring- powered extensions released to point inwards to the tubular body 505 in order to “measure” the radial distance between the inner arrangement 510 and the tubular body 505 at three or more points.
  • spring-powered extensions may restrict the flow of swelling agent into their respective components 510 A, thereby allowing those swellable sections nearest the tubular to be expanded outwards more rapidly than those farther away, and thereby centering the inner arrangement 510 at a uniform distance from the tubular body 505 .
  • the extensions may be refracted into the inner arrangement 510 .
  • Certain embodiments of the present disclosure may provide a simpler, cheaper, and easier means of coupling sensors to a formation or tubing/casing that are likely to provide much surer coupling.
  • Most previous sensor deployments have used cement coupling (generally for permanent deployments), mechanical coupling such as clamp arms and bow springs (for both permanent and retrievable applications), magnetic coupling (retrievable applications), or even uncoupled deployments (e.g., sensors attached to tubing run inside of casing) that rely on friction and bending stresses.
  • Methods and systems of the present disclosure may eliminate the need for mechanical clamp arms (which may have leak issues with seals and high temperature), bow springs (which may have poor high frequency response and resonances), magnets (which may have limited coupling and resonances), or cementing.
  • Methods and systems of the present disclosure may also improve omnidirectional array fidelity, even for retrievable operations and settings where the swelling elements may be subsequently de-swelled, detached or torn off to facilitate tool retrieval or repositioning.
  • Certain embodiments of the present disclosure may allow for long-term emplacement in difficult open-hole environments without permanently cementing an instrument in place. This may simplify operations and may allow for retrievable sensor devices if difficulties occur during emplacement. This may avoid the situation in open-hole environments where mechanical arms or bowsprings can sink into soft materials in the hole and cause poor tool coupling. Such a situation can occur in shales and many shallow boreholes where sensors would otherwise have to be cemented in permanently to obtain good coupling.
  • Certain embodiments may allow for improved signal fidelity for microseismic monitoring of hydraulic fractures by ensuring better coupling compared to clamp arms, bow spring, magnets, or other emplacement methods, thus attenuating or eliminating longitudinal tool vibrations that degrade the recording fidelity of elastic body wave motion parallel to a tool axis.
  • swelling elements may effectively dampen acoustic noise generated by flow in production tubulars as well as noise received via the tubulars. The swelling elements may even yield sensor isolation from the tubulars even though swellable elements are in contact with both. Additionally, certain embodiments may allow for securely planting surface instruments in soft, crumbly ground.
  • Certain embodiments may remove directional bias of recorded signals by emplacing sensors in the center of a borehole with equal response from all directions, as opposed to a likely higher fidelity on the side of the borehole on which it is deployed when clamped or cemented. Certain embodiments may eliminate the need for a nearby vertical observation well by allowing for installation of tools in the injection/production well with good coupling and a degree of noise suppression from tubing activities.
  • Certain embodiments may be used for time-lapse seismic monitoring and/or time-lapse deformation monitoring throughout the life of the reservoir for more permanent installations.
  • the time-lapse seismic application requires a source on either the surface or in a nearby well; time-lapse deformation only requires continuous measurements of tilt or other deformation parameters.
  • certain embodiments provide a fast, easy method to deploy sensors, potentially allowing them to stabilize much faster—which translates to a shorter lead time for monitoring.
