... reservoirs. Because the proposed techniques are nondestructive, the same samples can be applied for multiple tests including special core analysis (or SCAL). Laboratory tests were performed on cylindrical samples of 0.03×0.03 m ( Fig. 2 ). First, the samples were cleaned from hydrocarbons and salts...
