Abstract: To optimize the efficiency of a perforating tool system, downhole conditions may be simulated to determine the optimal configuration for the perforating tool system. A simulated wellbore is disposed in a pressure vessel and coupled to a target composite core assembly. A perforating tool system is disposed in the simulated wellbore above the target composite core assembly. The target composite core assembly includes an outer shell. The outer shell comprises a material that supports a rubber bladder or flexible jacket that is disposed about the outer shell. The outer shell isolates the overburden fluid and pressure from the inner core during a radial flow test to more accurately simulate conditions downhole. A parameter of a perforating tool system may be altered based, at least in part, on a result from the radial flow test.

Abstract: Techniques are disclosed for connecting a printing plate to a print cylinder or surface. The techniques may be implemented, for instance, with respect to a printing plate, a print cylinder, a print sleeve, or some combination thereof. In an embodiment, a field of mechanical fasteners is provisioned on a printing plate, and a complementary field of mechanical fasteners is provisioned on a print sleeve or cylinder. The mechanical fasteners collectively operate to provide a mechanical bond or interface that inhibits lateral and rotational movement of the plate during printing operations, and can also be configured to manage backlash between engaging surfaces of the interface. In some cases, backlash management includes use of cushion effect integral with the mechanical bond itself and/or unidirectional and possibly angled fastener elements to provide a snugging effect.

Abstract: A chamber blade system maximizes ink flow at an anilox doctor blade by including a heating element adjacent the doctor blade to heat ink adjacent the blade. The heating element may be a heat strip next to an anilox doctor blade that heats the ink adjacent the doctor blade and temporarily reduces the ink viscosity to improve the flow of ink in the vicinity of the blade. Doctoring blades with a ceramic tip coating may be configured to allow a small amount of controlled ink flow through that can wet the lands thereby reducing the hydrodynamic back pressures and friction when trying to force the ink into anilox cells.
