System and method for transmitting downhole data to the surface
First Claim
1. A system for transmitting downhole data to the surface comprising:
- a communications medium operable to provide data transfer to the surface;
a first downhole instrument operably associated with the communications medium, the first downhole instrument being operable to measure a first downhole parameter and transmit first data at a first time relative to the first downhole parameter to the surface via the communications medium; and
a second downhole instrument operably associated with the communications medium, the second downhole instrument being operable to measure a second downhole parameter and transmit second data relative to the second downhole parameter to the surface via the communications medium such that the first data is interleaved with the second data.

Abstract
A system and method are disclosed that provide for transmitting data from a downhole location to the surface. In one embodiment, a communications medium provides data transfer capabilities to the surface. A first downhole instrument is associated with the communications medium in order to measure a first downhole parameter and transmit first data relative to the first downhole parameter to the surface via the communications medium at a first time. A second downhole instrument is associated with the communications medium in order to measure a second downhole parameter and transmit second data relative to the second downhole parameter to the surface via the communications medium at a second time such that the first data is interleaved with the second data.
