Abstract
A method for improving a quality of data received from a downhole tool in a wellbore includes receiving a first block of data from a downhole tool in a wellbore. The first block of data represents a first measurement captured by the downhole tool during a first period of time. At least a portion of a bit budget for a second block of data is allocated to the first block of data to produce an updated first block of data. The method also includes receiving the second block of data from the downhole tool in the wellbore. The second block of data represents a second measurement captured by the downhole tool during a second period of time.

A method for improving a quality of data received from a downhole tool in a wellbore, comprising:
- receiving a first block of data from the downhole tool in the wellbore, wherein the first block of data represents a first measurement captured by the downhole tool during a first period of time;
- allocating at least a portion of a bit budget for a second block of data to the first block of data to produce an updated first block of data;
- and
- receiving the second block of data from the downhole tool in the wellbore, wherein the second block of data represents a second measurement captured by the downhole tool during a second period of time.
A method for improving a quality of data received from a downhole tool in a wellbore, comprising:
- receiving a first block of data from the downhole tool in the wellbore, wherein the first block of data represents a first measurement captured by the downhole tool during a first period of time;
- determining that at least a portion of the first block of data is corrupted;
- in response to determining that at least a portion of the first block of data is corrupted, transmitting a command to the downhole tool in the wellbore instructing the downhole tool to allocate at least a portion of a bit budget for a second block of data to the first block of data to produce an updated first block of data, wherein the portion of the bit budget for the second block of data that is allocated to the first block of data is used to re-transmit the portion of the first block of data that was corrupted;
- and
- receiving the second block of data from the downhole tool in the wellbore, wherein the second block of data represents a second measurement captured by the downhole tool during a second period of time.
