Abstract: Systems and methods presented herein provide for the generation of acoustic waves for acoustic stimulation, as well as for analysis of subterranean formations, using downhole tools and associated equipment that are not conventionally designed to do so. For example, in certain embodiments, formation testing tools, formation, measurement tools, inflatable packers, and so forth, may be controlled by control systems to, for example, create pressure pulses that generate the acoustic waves. In addition, in certain embodiments, a tool conveyance system that conveys a formation testing or measurement tool into a wellbore may include acoustic receivers that may detect the acoustic waves after they reflect from subterranean features of the formation.

In some embodiments, the mechanical flow assembly includes a fluid arm that directs a flow of fluid into an expandable element to inflate the expandable element, and a support arm that provides support to the fluid arm during inflation of the expandable element. In some embodiments, the mechanical flow assembly is rotatably coupled to a piston and a packer conduit of the expandable element via linkages.

Abstract: An inflatable packer assembly comprising a first fixed sleeve fixed to a mandrel, a first sliding sleeve moveable along the mandrel, and a first inflatable member connected to the first fixed sleeve and the first sliding sleeve. A second sliding sleeve is moveable along the mandrel, and a second inflatable member is connected to the first sliding sleeve and the second sliding sleeve. A second fixed sleeve is fixed to the mandrel and slidably engages the second sliding sleeve. An inflation flowline disposed within the mandrel is in fluid communication with interiors of the first and second inflatable members for inflating the first and second inflatable members to isolate a portion of a wellbore penetrating a subterranean formation. An injection flowline is disposed within the mandrel for injecting a fluid into the isolated wellbore portion at a high enough pressure to create microfractures in the subterranean formation.
