Definitions

  • the present disclosure relates to subterranean operations and, more particularly, to an apparatus and methods for monitoring and characterizing fluids in a subterranean formation.
  • drilling operations play an important role when developing hydrocarbon wells.
  • a drill bit passes through various layers of earth strata as it descends to a desired depth.
  • Drilling fluids are commonly employed during the drilling operations and perform several important functions including, but not limited to, removing the cuttings from the well to the surface, controlling formation pressures, sealing permeable formations, minimizing formation damage, and cooling and lubricating the drill bit.
  • Maintaining fluid pressure in the wellbore is often critical to these and other subterranean operations in a wellbore.
  • subterranean operations such as drilling or completing wells
  • Fluids placed in a wellbore may migrate or flow into another portion of the subterranean formation other than their intended location, for example, in an area of the formation that is more porous or permeable.
  • Fluid loss may result in, among other problems, incomplete or ineffective treatment of the formation, increased cost due to increased volumes of fluid to complete a treatment, and/or environmental contamination of the formation. While treatment fluids are often formulated and wells are often constructed so as to reduce the likelihood or amount of fluid loss into the formation, fluid loss still may occur, particularly in damaged or highly permeable areas of a subterranean formation or wellbore.
  • Conventional methods of detecting fluid loss typically involve measuring the amount of fluid pumped into the wellbore and comparing that with the amount of fluid circulated out of the wellbore.
  • such methods are usually only performed after the operation using the fluid has been completed, and do not provide enough information during the operation to make adjustments to attempt to compensate for the fluid loss or otherwise remedy whatever is causing the loss of fluid. This may require performing the same treatment or operation on the same wellbore multiple times until it can be performed without significant fluid loss.
  • such methods typically are not capable of identifying the specific fluid that was lost into the formation, the identity of which may be important in order to compensate for the lost fluid and/or remedy or prevent additional problems ⁇ e.g., formation damage, environmental problems, etc.) that may result from the loss of particular fluids into the formation.
  • well logging instruments may be used to probe subsurface formations to determine formation characteristics.
  • Sonic tools are an example of well logging tools that may be used to provide information regarding subsurface acoustic properties that can be used to analyze the formation.
  • an acoustic logging instrument or tool is lowered into a wellbore that transverses a formation of interest.
  • the acoustic logging tool may be mounted to the drill collar or other devices and directed downhole.
  • the receiver(s) of the acoustic logging tool are typically sensitive to undesired acoustic noise that may result from normal drilling operations.
  • the undesired acoustic noise may radiate with reduced attenuation through a hard steel drill collar.
  • the acoustic noise may then couple to the receiver of the acoustic logging tool and be converted into electrical noise along with the desired signal.
  • This background noise may be a result of the downhole operations or produced by other acoustic sources and therefore may introduce an error in the measurements by the acoustic logging tool.
  • traditional logging tools often involve complex downhole equipment and sensors which may be expensive to operate and maintain. It is therefore desirable to detect the level of fluids from the surface and in real time.
