Abstract: A method, and related apparatus, involves providing one or more drill pipe segments and disposing a quantity of lost circulation material objects within the one or more drill pipe segments. A retention element is provided to retain the lost circulation material objects within the one or more drill pipe segments. The one or more drill pipe segments are connected to a drill string at a wellbore, and drilling fluid is flowed through the drill string. The flowing of drilling fluid through the drill string causes the retention element to release the lost circulation material objects to propagate further.

Abstract: A compact seismic source for seismic acquisition generating a humming signal includes a casing and a low-frequency reciprocating drive. The casing defines a fluid tight chamber and comprises a first casing section and a second casing section of roughly equal mass. The drive is disposed within the fluid tight chamber and, in operation, reinforces the natural reciprocating oscillation of the first and second casing sections relative to one another at a low seismic frequency. In one aspect, this action omni-directionally radiates the low frequency, humming seismic signal. On another aspect, the compact seismic source is substantially smaller than the wavelength of the low seismic frequency. Such a compact source may be deployed to omni-directionally radiate a low frequency, humming seismic signal during a seismic survey.

Abstract: A pipe cutting system (40) and method for cutting a helically wound steel pipe while the pipe is being moved in a direction (12) of its longitudinal axis uses a plasma torch (50) supported to be reciprocally movable parallel to the longitudinal axis and at an orientation relative to the pipe so that a plasma jet emitted by the plasma torch is directed upwardly toward the pipe. The plasma torch is arranged move at a speed that is synchronised with a speed at which the pipe is being moved in the direction of the longitudinal axis. The pipe is rotated during cutting so that the plasma torch circumferentially cuts the pipe while the pipe is being moved.
