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.

Abstract: An apparatus for remediating water wells comprises a plurality of retractable cutting blades suitable for cutting openings in a well casing. The retractable cutting blades and corresponding drive mechanism are organized to be lowered through a well casing. At certain depths, the retractable blades are extended to cut openings in the well casing. The apparatus also includes inflatable retention elements both above and below the retractable blades to create a fluid seal within the well casing. A solidifying, waterproof slurry is injected to flow through the openings via a slurry delivery mechanism, and thereby create a waterproof barrier outside the well casing at the level of a waterproof confining soil layer.

Abstract: The invention provides a method and apparatus for use in a wellbore gravel pack operation. The method comprises providing an apparatus in a downhole annulus. The apparatus comprises a mandrel and a swellable element formed from a material selected to increase in volume when exposed to a downhole stimulus. The method comprises placing a gravel pack below the apparatus via the downhole annulus in which the apparatus is located, and placing a gravel pack above the apparatus. Subsequent to placing the gravel packs, the swellable element is increased in volume to create an annular barrier in the wellbore. The invention allows isolation of multiple intervals of a well in a single gravel pack operation using swellable elastomers, and does not rely on the use of shunt tube alternate path systems.

Abstract: A method and/or a system determines mechanical properties of a fluid-bearing formation. One or more packers may be used to measure and/or collect data regarding mechanical properties of a formation. The formation characteristics may be, for example, the stability of the formation, design parameters for frac-pack/gravel-pack operations, and sand production. The packer may expand within a wellbore of a formation until enough pressure is applied to fracture a wall of the wellbore. Before, during and/or after the fracturing of the wall, multiple measurements may be taken by the packer. After fractures are initiated, fluid may be pumped into and/or drawn from the formation using drains disposed on the packer. Additional packers may be used above and/or below the packer for isolating intervals of the wellbore.

Abstract: Apparatus and method for creating a barrier across an annulus in a well bore. First and second morphable sleeves are arranged side by side on a tubular body and sealed thereto to. Adjacent ends of each sleeve meet at a valve housing having a valve arrangement with a first position in which fluid flows from the throughbore of the tubular body to the first and second sleeves and a second position which prevents the flow of fluid between the throughbore, the first chamber and the second chamber. At opposing ends of the sleeves rupturable barrier devices are positioned. The sleeves can be morphed together and by rupturing the barriers, each side of the barrier is active to pressure and collapse is prevented regardless of the pressure differential across the barrier.
