Abstract: A wireline width measuring apparatus and associated method which may be used to measure static and dynamic fracture width in fractures used for energy storage, water injection, or hydrocarbon production. In one embodiment, the method comprises determining a depth of the formation fracture, determining the depth of the bottom of the wellbore, positioning a caliper tool string comprising a caliper apparatus at the bottom of the wellbore, wherein the caliper apparatus is positioned at a depth capable of measuring movement of a window cut into a casing of the wellbore at the depth of the formation fracture, inflating the fracture by injecting a fluid into the fracture, uninflating the fracture by producing the fluid from the fracture, and measuring movement of the window cut into the wellbore while the fracture is inflated and uninflated.

Abstract: An isolation system contains an isolation packer and a setting tool. The isolation packer comprises an inner mandrel, an expandable sealing around the inner mandrel, the expandable sealing includes a center sealing element, the outer diameter of the center sealing element in a relaxed state is larger than the outer diameter in a stretched state. The isolation packer further comprises an actuator to stretch the expandable sealing. the setting tool comprises a motor, a set of gear reducer, and an adapter, the adapter comprises a plurality of detents having ability to couple with the actuator when the adapter rotate anticlockwise and to decouple from the connector when the adapter rotate clockwise. The adapter also comprises a plurality of holes to receive shear screws.
