Disclosed combination impact tool generates optimized linear hammering and vibrational impacts. Flow of pressurized fluid through an upper section of the tool generates linear hammering impacts, and flow of pressurized fluid through a lower section of the tool generates vibrational impacts. Flow of pressurized fluid through the lower section induces an eccentric arm to rotate and cause vibrational impacts. While frequency of hammering impacts can be controlled by varying pressure of the fluid flowing through the upper section, the frequency and amplitude of vibrational impacts can be controlled by varying weight of the eccentric arm and by varying pressure of the fluid flowing through lower section.

The invention relates to a clamping head assembly for clamping a drill pipe element, comprising a clamping head base, at least one clamping jaws base body which is radially adjustable at the clamping head base between a clamping position and a releasing position relative to the drill pipe element, and at least one adapter element at the clamping jaws base body, wherein the adapter element is adapted to a shape of the drill pipe element to be clamped and is configured to abut and clamp the drill pipe element in the clamping position. According to the invention, it is provided that the adapter element is releasably arranged on the clamping jaws base body and can be locked by means of an actuatable locking device, and that the locking device comprises at least one latch element adjustable between a locking position, in which the adapter element is locked and secured to the clamping jaws base body, and a release position, in which the adapter element is released and removable from the clamping jaws base body.

Systems and methods for installing a coiled tubing pumping system in a well permit the use of a standard wellhead. A method for installing the coiled tubing pumping system includes the steps of connecting a continuous length of coiled tubing to the coiled tubing pumping system, lowering the coiled tubing pumping system and coiled tubing into the production tubing, and temporarily supporting the weight of the coiled tubing pumping system with an installation kit. The method continues with the steps of cutting the continuous length of coiled tubing to form a coiled tubing segment attached to the coiled tubing pumping system, attaching a deployment assembly to an upper end of the coiled tubing segment connected to the coiled tubing pumping system, and lowering the deployment assembly, the coiled tubing segment and the coiled tubing pumping system into the well until the deployment assembly lands on the seating element.

A laser system for freeing downhole equipment includes a laser tool having an inner diameter larger than an outer diameter of the downhole equipment and a means for generating a ring-shaped collimated laser beam. The laser system further includes a work string with the inner diameter larger than the outer diameter of the downhole equipment. The laser tool is installed on the work string and the work string is lowered around the downhole equipment. Upon lowering the work string to a position in which the laser tool is located proximate to an obstruction of the downhole tool, the laser tool emits the ring-shaped collimated laser beam so as to clear out an annulus space between the downhole equipment and a wellbore wall in order to free the downhole equipment.

Systems and methods for fishing a metal object from a subterranean well include a fishing tool with housing, the housing being an elongated member having an internal bore. A first electromagnetic assembly is located within the internal bore of the housing and a second electromagnetic assembly is located at an outer diameter surface of the housing, the second electromagnetic assembly being moveable between a contracted position and an extended position where the second electromagnetic assembly extends outward from the housing. The first electromagnetic assembly is operable to generate a first magnetic force with an adjustable magnitude. The second electromagnetic assembly is operable to generate a second magnetic force with an adjustable magnitude, the first magnetic force and the second magnetic force having a same magnetic polarity.
