  • Method for minimizing mud solids invasion of core samples obtained during subsurface coring
    Patent number: 4848487
    Abstract: A core sample of an earth formation is obtained by drilling with a coring bit and circulating a coring fluid through the coring bit. The coring fluid contains no mud solids for contaminating the core sample or, in the alternative, contains drilling mud mixed with a bulk material which invades the core sample and occupies the core sample pore spaces preferentially over mud solids. This bulk material is more readily removed from the core sample by cleaning than mud solids.
