METHOD FOR THE PRESERVATION OF IN-SITU SOLUBLE SALT CEMENTS THAT ALLOWS THEIR QUANTIFICATION WITHIN SUBTERRANEAN ROCKS

摘要

A method of coring to preserve subterranean soluble salt cements gives careful consideration to the selection and use of drilling fluids, specific logging of the zone of interest, displacing the near wellbore with an agent that when cured has either bound all subterranean water or cemented up all the available pore space, coring of the target formation zone containing the cured agent and retrieval of pressurized core material that allows CT scanning.
