Abstract
Methods and systems for conducting downhole operations including collecting downhole dynamic event data using a downhole tool, wherein the downhole dynamic event data is time-domain data, processing the collected downhole dynamic event data using a computing system located downhole to convert the time-domain data into frequency-domain data, and extracting digital filter coefficients from the frequency-domain data.
Claims20
A method of conducting downhole operations, the method comprising:
- collecting downhole dynamic event data using a control element of a downhole tool, wherein the downhole dynamic event data is time-domain data and the downhole tool is disposed in a borehole;
- processing the collected downhole dynamic event data using a downhole computing system located downhole that is operably connected to the control element, the computing system configured to convert the time-domain data into frequency-domain data;
- and
- extracting digital filter coefficients from the frequency-domain data to enable reconstruction of at least one of downhole dynamic event spectrum and the time-domain data.
A system for conducting downhole operations, the system comprising:
- a downhole tool disposed in a borehole, the downhole tool arranged to perform a downhole operation;
- and
- a downhole computing system configured to:
- collect downhole dynamic event data from the downhole tool, wherein the downhole dynamic event data is time-domain data;
- process the collected downhole dynamic event data to convert the time-domain data into frequency-domain data;
- and
- extract digital filter coefficients from the frequency-domain data.
