Thermobaric tests are performed on Bazhenov oil-bearing shale containing above 10% of kerogen in view to determine its rheological properties. The test specimen under a statistical axial load is heated stepwise at temperatures T-n = 60, 100 and 150 degrees C with measurements of height H(t). The temperature is risen if relative velocity of H gets less than 0.05. Deformation of the specimen is described by Kelvin-Voigt model, within which the inverse problem is stated and solved to determine Young module En and effective viscosity eta(n) of rocks by H(t). The results of solution are approximated by two-parameter exponential functions, E = E(t) and eta = eta(t) relationships are established.
