  • a perforating gun string may be lowered into the well and guns fired to create openings in casing and to extend perforations into the surrounding formation.
  • a method of orienting a tool in a wellbore includes identifying a desired orientation of an oriented device in the tool at a given wellbore interval.
  • the oriented device is angularly positioned with respect to a positioning device, and a tool is lowered downhole with the positioning device guiding the tool so that the oriented device is at substantially the desired orientation when the tool reaches the given wellbore interval.
  • an apparatus for orienting a tool in a wellbore includes a motor coupled to the tool, an anchor to fix the apparatus in the wellbore, and a measurement device adapted to measure a relative bearing of the tool.
  • the motor is activable to rotate the tool with respect to the anchor based on the relative bearing data received from the measurement device.
  • Fig. 1 is a diagram of an embodiment of a tool string positioned in a cased wellbore.

  • Fig. 4 is a diagram of a modular tool string according to a further embodiment that is capable of connecting to a number of different sondes.
  • Figs. 5 and 6 illustrate position devices in the tool strings of Figs. 2 A and 2B.
  • Fig. 7 illustrates relative bearing and azimuthal angles associated with a downhole tool.
  • a formation zone 102 having producible fluids is adjacent a wellbore 104 lined with casing 100.
  • the location of the formation zone 102 and its stress characteristics may be identified using any number of techniques, including open hole (OH) logging, dipole sonic imaging (DSI), ultrasonic borehole imaging (UBI), vertical seismic profiling (VSP), formation micro-imaging (FMI), or the Snider/Halco injection method (in which tracers are pumped into the formation 102 and a measurement tool is used to detect radioactivity to identify producible fluids).
  • Such logging techniques can measure the permeability of the formation 102. Based on such measurements, the depth of a zone containing producible fluids can be determined. Also, the desired or preferred fracture plane in the formation 102 can also be determined. The preferred fracture plane may be generally in the direction of maximum horizontal stresses in the formation 102. However, it is contemplated that a desired fracture plane may also be aligned at some predetermined angle with respect to the minimum or maximum stress plane. Once a desired fracture plane is known, oriented perforating equipment 108 may be lowered into the wellbore to create perforations that are aligned with the desired plane. 3

  • Oriented perforating may also be practiced for doing directional squeeze jobs. If the current surrounding the pipe contains a void channel, the direction of that channel can be determined using a variety of methods and tools such as the USIT (Ultrasonic Imaging Tool). Once the direction is known, oriented perforating may be executed accordingly.
