Abstract
Data is received downhole from a downhole logging tool to produce received data. The received data is processed to produce processed data. A binary formatting option is selected from a group of binary formatting options, wherein applying the selected binary formatting option to the processed data produces fewer bits than applying any other binary formatting option of the group of binary formatting options to the processed data. The selected binary formatting option is applied to the processed data to produce binary data. The binary data is transmitted uphole. The binary data is received uphole. The received binary data is decompressed to produce uncompressed data. The uncompressed data is processed uphole.
Claims20
A method comprising:
- receiving nuclear magnetic resonance (NMR) data downhole from a downhole logging tool to produce received NMR data associated with a subsurface formation;
- processing the received NMR data to produce processed NMR data;
- compressing the processed NMR data;
- selecting a binary formatting option from a group of binary formatting options based on a total porosity value of the subsurface formation;
- applying the selected binary formatting option to the processed NMR data to produce binary data;
- transmitting the binary data uphole;
- receiving the binary data uphole;
- decompressing the received binary data to produce uncompressed data;
- and
- processing the uncompressed data uphole.
A non-transitory machine-readable medium including program code executable on one or more processors, the program code comprising instructions to:
- receive nuclear magnetic resonance (NMR) data downhole from a downhole logging tool to produce received data associated with a subsurface formation;
- process the received NMR data to produce processed NMR data;
- compress the processed NMR data;
- select a binary formatting option from a group of binary formatting options based on porosity value of a subsurface formation;
- apply the selected binary formatting option to the processed NMR data to produce binary data;
- transmit the binary data uphole;
- receive the binary data uphole;
- decompress the received binary data to produce uncompressed data;
- and
- process the uncompressed data uphole.
A system comprising:
- a nuclear magnetic resonance (NMR) tool;
- a control unit coupled to the NMR tool to control the NMR tool;
- and
- a downhole processor coupled to the NMR tool and the control unit configured to execute program code comprising instructions to:
- receive data downhole from the NMR tool to produce received NMR data;
- process the received NMR data to produce processed NMR data associated with a subsurface formation;
- compress the processed NMR data;
- select a binary formatting option from a group of binary formatting options based on a porosity value of the subsurface formation;
- apply the selected binary formatting option to the processed data to produce binary data;
- transmit the binary data uphole;
- receive the binary data uphole;
- decompress the received binary data to produce uncompressed data;
- and
- processing the uncompressed data uphole.
