| There is provided a downhole hammer including a drill bit (2) retained by short (4) and long (5) drive pins in the bore of a driver chuck (1). The chuck (1) and bit (2) shank have machined longitudinal grooves (3), every second bit shank groove being blind and connected to the adjacent open groove by a short-pin-length relief. The shorter pins (4) are inserted into the visible holes formed by the alignment of the open drill bit grooves and driver chuck grooves (3). The chuck (1) is then indexed which shunts the short pins (4) sideways until the longer pins (5) are insertable. The driver chuck (1) and drill bit (2) are engaged rotationally. The bit (2) slides by the desired distance due to the shorter pins (4) being entrapped in the blind grooves. The arrangement does not require a bit shank extension to accommodate a conventions bit retainer ring. ® KIPO & WIPO 2009 | ||||||

| Certain aspects of the present invention are directed to a distributed inflow control device that can be disposed in a wellbore through a fluid-producing formation. The distributed inflow control includes a shroud that can be disposed in the fluid-producing formation. The shroud circumferentially covers a section of a tubing string. The shroud includes a profile having multiple flow paths between the fluid-producing formation and an inner volume of the section of the tubing string. Each flow path restricts a fluid flow through the flow path and is independent of each other flow path. The distributed inflow control device also includes a seal over the profile including the flow paths. The seal causes fluid to flow from an inlet to an outlet of each flow path and prevents fluid from entering or exiting each flow path at a point other than the respective inlet or the respective outlet. | ||||||
