Computer measurements and numerical calculation of carbonate rocks thermal maturity, case study Brač-1 well beta

In the Brač-1 beta well the temperatures and depth of rock units had been measured and constructed. The burial history lines are drawn, and thermal maturity calculated with emphasis on potential mature rocks. The interval (iTTI) and consequently total (ΣTTI) time-temperature indices of 23.48 indicated on the maturity window deeper than 5 km. The oldest rock of the Lower Triassic reached thermal maturity 54 ma ago. Those rocks are regionally sometimes rich in sulphur, with kerogene type II and rarely type I. In researched well is also mapped large regional reverse fault, which thrusted thick interval of the Triassic (900 m), Jurassic (900 m) and Lower Cretaceous (140 m) rocks. Temperature logging at different depths along at the well is relatively expensive procedure. However, such data sometimes can be approximated with average annual soil temperature (neutral layer) and temperature of the bottom. From such data can be calculated average (present) geothermal gradient. The device for neutral layer temperature measurement, based on Raspberry Pi, Sense HAT and Python code, is integra part of this innovation.
