A method and system for labeling and identifying a sample, including a rock core sample, after determining a physical primary label has been compromised is provided. The method includes labeling the sample by placing a physical primary label on the sample or sample container, creating a first rollout image of the sample for a secondary label, and storing the first rollout image in a secondary label digital database with a sample identifier. The method continues for identifying the sample after determining the physical primary label has been compromised by creating a secondary rollout image of the sample and searching the secondary label digital database using the second rollout image to create a plurality of matching scores using a machine learning or deep learning image matching technique. The matching scores are then evaluated to determine an identify of a sample and the sample is re-labelled using a replacement primary label.

Sample labeling method using image-matching

A cleaning system for oil and gas core samples includes a vapor extraction chamber configured to receive and drain liquid solvents, a movable portion including a movable tray, a lid and a sample cooler, a heater configured to provide heat to the chamber to produce heated and vaporized solvents, a vapor extraction chamber chiller, a controller, and a dryer. A method of cleaning oil and gas core samples includes a vapor extraction step and a drying step. The vapor extraction step includes transferring core samples into and sealing the vapor extraction chamber, heating liquid solvents and maintaining an elevated temperature and a positive pressure in the chamber until an extraction time expires, cooling and transferring the core samples out of the chamber. The drying step includes transferring the cleaned core samples into a dryer, drying the core samples until substantially free of solvents, and cooling the core samples.

A method for determining the electrical properties of a core sample having an initial saturation S, an initial true resistivity R, and a porosity ϕ, including the steps: preparing a brine having a resistivity R, flushing the core sample with the brine, determining a first true resistivity Rat a first saturation S, once the resistivity Rof the brine going into the core sample is the same as the resistivity Rof the brine going out of the core sample, determining a function R=f(S) describing the dependency of the true resistivity Rof the core sample and the saturation Sin the core sample, based on the initial saturation S, initial true resistivity R, first true resistivity R, and first saturation S, second true resistivity R, and first saturation S, determining the resistivity Rof the fully saturated core sample by estimating the function R=f(S) to full saturation of the core sample at S=100%, determining a resistivity index at the S, S, Sdetermining a saturation exponent n using linear regression of the log-log plot of Ivs. S.
