A tubing nipple impression device for use within downhole tubing includes a driver body, a stopping disk, first and second impression arms, and upper and lower radial springs. The driver body extends in an axial direction along a vertical axis of the downhole tubing. The driver body further includes a nose portion, and first and second driver arms that abut against the stopping disk. The shear pin attaches the driver body to the stopping disk. The first and second impression arms are fixed to the stopping disk, and are further connected to each other with upper and lower radial springs. The first and second impression arms are actuated by the nose portion to form first and second impressions complimentary to first and second portions of a tubing nipple, respectively, when the first and second impression arms abut against the tubing nipple.

A tool for creating impressions of downhole objects comprising a cylindrical outer casing, a top plate, a plunger, an end plate, a lever, a pressure lock plate, a pressure base, a main spring platform, a main spring, and a plurality of elongated rods. The elongated rods extend from beneath the main spring platform through the pressure lock plate, the pressure base, and the end plate. Each elongated rod is surrounded by a rod spring and a collar. The rod spring extends from the bottom of the pressure base to the collar. The pressure lock plate moves laterally when the lever pivots from a locked to an unlocked position, thereby aligning the plurality of holes in the pressure lock plate with the plurality of holes in the pressure base and enabling the elongated rods to move longitudinally within the tool.

An apparatus, method, and system for monitoring wellbore deformation is disclosed. The apparatus includes an expandable annular cylindrical packer and a plurality of assemblies mounted on an exterior circumferential surface of the packer. The plurality of assemblies are configured to be pressed against a wellbore surface by the packer. Each of the assemblies includes at least one fiber-optic coil embedded in a sheet of deformable substrate, a tray-shaped receptacle formed from a low thermal conductivity material and attached along the rim to an edge of the sheet with a pressure tight-seal, and an optical coupler configured to couple the fiber-optic coil to a fiber-optic cable. The assemblies further include a pressure-tight compartment containing a high-pressure inert gas that is formed by the receptacle, the sheet, and the seal.

An apparatus includes a sand bailer and a lead impression block. The sand bailer is configured to be disposed in the tubular and obtain a sample of the obstruction. The sand bailer includes a piston movably disposed in a cavity of a barrel and a valve connected to a downhole end of the barrel and configured to control hydraulic communication between an orifice of a hollow body of the valve and a cavity of the barrel by opening and closing. The piston is configured to create a suction pressure in the cavity of the barrel to open the valve and retrieve the sample of the obstruction into the cavity and wherein the valve is configured to close to hold the sample of the obstruction in the cavity of the barrel. The lead impression block is connected to the hollow body of the valve in the sand bailer. The lead impression block is configured to set against the obstruction, using the sand bailer, and obtain an impression of the obstruction.

An apparatus includes a hydrostatic bailer and a lead impression block. The hydrostatic bailer is disposed in the well and removes debris from the fish using a plunger, a shear pin, and a valve. The valve controls hydraulic communication between an orifice of a hollow body of the valve and a cavity of the hydrostatic bailer by opening and closing. The shear pin is configured to shear and allow the plunger to move within the hydrostatic bailer to open the valve and remove the debris from the fish. The lead impression block is connected to the hollow body of the valve in the hydrostatic bailer. The lead impression block is configured to set against the fish, using the hydrostatic bailer, and obtain an impression of the fish on a single run into the well in which the debris is removed from the fish.
