To estimate minimum horizontal stress in the field the leak-off-test (lot) and mini-frac tests are practiced by companies. with a simple pressure-time plot, explain how the magnitude of minimum horizontal stress is estimated from these two field tests. also, compare the advantages and shortcomings of each method.
the information obtained from which of the above two field tests (i. e. lot and mini-frac) will allow to estimate the magnitude of the maximum horizontal stress assuming the formation strength properties are known? support your answer by referring to the pressure-time plot and justify your statements.
