Abstract: A system and method are provided for providing electromagnetic (EM) measurement-while-drilling (MWD) telemetry capabilities using an existing mud-pulse MWD tool. An EM tool intercepts the output from the mud-pulse tool and generates an EM signal that mimics a mud-pulse pressure signal. The EM signal is intercepted at the surface by a receiver module that conditions the signal and inputs the signal into the existing pulse tool receiver. Since the EM signal mimics a mud-pulse signal, the pulse tool receiver does not require software or hardware modifications in order to process an EM telemetry mode. The EM tool can be adapted to also provide dual telemetry by incorporating a conventional pressure pulser that would normally be used with the pulse tool.

Abstract: Downhole tools comprise a housing chamber with an expandable member disposed therein. An interior of the expandable member is in fluid communication with an outside environment so that hydrostatic pressure can act on an inner wall surface of the expandable member. The outer wall surface of the expandable member partially defines a sealed chamber within the housing chamber such that expansion of the expandable member due to an increase in hydrostatic pressure causes the volume within the sealed chamber to decrease, thereby energizing the sealed chamber. Thus, an increase in hydrostatic pressure within an outside environment is compensated. Further, when the hydrostatic pressure within the outside environment decreases, the energized sealed chamber causes contraction of the expandable member, thereby compensating for the decrease in hydrostatic pressure.
