Efficient adaptive seismic data flow lossless compression and decompression method

An efficient adaptive seismic data flow lossless compression and decompression method, for efficient compression of 24-bit analog-to-digital converted geophysical prospecting equipment data which is a seismic data;

• wherein real-time lossless compression of data streams and an original 24-bit 3-byte format of sampled data is compressed to a 1, 2, or 3-byte format wherein a small amount of data is converted to 4 bytes using a specific encoding process the method comprising:
• determining required bits before data compression based on a size of an original data,
• compressing data in the [0-63] and [−64-−1] intervals into 1 byte;
• compressing data in the [64-8191] and [−8192-−65] intervals into 2 bytes;
• compressing data in the [8192 to 104875] and [−104876-−8193] intervals into 3 bytes;
• leaving unchanged occupying bytes so they are the same as the original bytes;
• wherein other integer numbers outside of the above data intervals are represented by other 24-bit signed integer data;
• wherein, these integers require 4 bytes after running the compression algorithm operation;
• wherein in the data compression there are a required number of bytes and positive or negative values needed to select different operators and operation codes (opcodes) for a bit operation on specified bytes;
• wherein the opcode is a binary number of the byte;
• wherein there are 2 types of operators:
• (1) bitwise AND (&) and (2) bitwise OR (|);
• setting a specified bit position;
• ignoring the bytes lower than the specified byte position and not processing said lower bytes;
• deleting bytes higher than the specified byte position as invalid;
• wherein operators and opcodes for a first byte should be selected under different conditions.
