Abstract: A method can include interconnecting a well tool in a well tool assembly with a shock mitigating connection, the interconnecting being performed without threading, and positioning the well tool assembly in a wellbore. A well perforating assembly can include at least two perforating devices, a detonation train extending through the perforating devices, and a shock absorber positioned between the perforating devices. A method of assembling a perforating assembly can include, prior to installing the perforating assembly in a wellbore, pushing one perforating device connector into another perforating device connector without threading the connectors together, thereby: a) preventing disconnection of the connectors and b) making a connection in a detonation train. A well system can include a perforating assembly including multiple perforating guns and multiple shock absorbers. Each shock absorber may be interconnected between at least two of the perforating guns.

Abstract: A fracturing/gravel packing tool system with dual flow capabilities. A method of treating a well includes the steps of: flowing a fluid into the well through a work string while simultaneously flowing another fluid into the well through an annulus; and directing each of the fluids to the exterior of a well screen in the well. A well treatment system includes a slurry and a fluid flowed into a well. The slurry has an initial density, but the fluid is mixed with the slurry in the well, thereby causing the slurry to have a reduced density in the well. Another method of treating a well includes the steps of: installing a gravel packing assembly including a well screen in the well; flowing a slurry and a fluid into the well; mixing the slurry with the fluid, thereby reducing a density of the slurry in the well; and flowing the reduced density slurry about an exterior of the well screen.

Abstract: A slurry discharge device for use in a subterranean well can include a slurry flow passage extending longitudinally in the device. The slurry flow passage has flow passage sections. One flow passage section is positioned downstream of, and is laterally offset relative to, another flow passage section. Another slurry discharge device can include the slurry flow passage having multiple flow areas. One flow area is positioned in a downstream direction from, and is greater than, another flow area. A method of delivering a slurry into a subterranean well can include discharging the slurry from a tubular string through a first sidewall section of a slurry discharge device; and flowing only a returned fluid portion of the slurry through a second sidewall section of the slurry discharge device. The second sidewall section has a lateral thickness greater than a lateral thickness of the first sidewall section.
