Abstract
A method for transmitting data from a downhole tool is provided. In one embodiment, the method includes acquiring data for a formation fluid through downhole fluid analysis with a downhole tool in a well. The acquired data can include optical spectrum data measured with a spectrometer and other data. The method also includes generating time blocks of the acquired data and transmitting the time blocks from the downhole tool. More particularly, generating the time blocks may include compressing at least some of the optical spectrum data according to a first compression technique and compressing at least some of the other data according to one or more additional compression techniques. The compressed data can be packaged into the time blocks such that at least some of the time blocks include both compressed optical spectrum data and compressed other data for the formation fluid. Additional methods, systems, and devices are also disclosed.
