Abstract: A first sleeve is shifted with a ball landed on a seat to open treating ports. At the conclusion of the treating such as fracturing, another ball is dropped on a seat in an adjacent sleeve. The adjacent sleeve shifts to contact the initial sleeve that was shifted earlier. When the sleeves abut the treating ports are closed by the second sleeve and the production ports that are preferably screened are also opened by the shifting of the second sleeve against the first sleeve. The first sleeve hits a travel stop in the housing to produce the full open position for the treating ports. The balls can be progressively larger in a bottom up direction for the procedure or the balls can all be the same size as the landing of a ball on the first sleeve reconfigures the sleeve above for the same sized ball.

The multilayered unit can be embedded in a component, attached to a component, or disposed between two components of a downhole assembly. The downhole assembly containing the multilayered unit has controlled disintegration in a downhole environment.

Abstract: An intelligent dart or ball or other shape is dropped or pumped into a borehole that has multiple valves for access to the formation through which fractures are initiated. The intelligent object engages with the valves as it passes with retractable engagement dogs that are outwardly biased but not to the degree needed to find support unless the valve in question is the one that needs to be operated. In that event the dogs become supported and pressure is applied to the object to shift the valve to the open position. The object can be released at a later time remotely or can be milled out. Subsequent objects can be landed in the same sleeve after the initial object is released to close it or to close the open port by moving a second sleeve against a first sleeve. Fracturing in any order is envisioned.

Abstract: A device, system, and method for locating collars along a casing string. The device includes a casing collar locator (CCL) and a valve in communication with the CCL connected to a work string. Fluid is pumped down the work string as the device is used to locate collars along a string. Upon detection of a collar, the CCL sends a signal to the valve, which causes the actuation of the valve to decreases a flow area within a work string. The decrease in flow area causes a pressure increase within the work string, which may be detected at the surface to indicate the detection of a collar. The device may include an amplifier and power source to amplify the signal from the CCL to the valve. The CCL may detect collars by a change in magnetic flux or by the detection of a signal emitted by individual collars.

The packer may include upper and lower sealing elements, and at least one thermal memory shape material sub positioned between the sealing elements. The thermal memory shape material sub may have a first outer diameter at a first temperature and a second larger outer diameter at a second temperature.

The outer diameter of the sub may be selectively increased to temporarily decrease the annular area in which debris and/or materials may collect and potentially cause the packer to become stuck within the wellbore. Prior to moving the packer to a different location, the outer diameter of the sub may be decreased to increase the annular area.
