Lecture event entitled “PETROLEUM CHALLENGE NOWDAYS IN GLOBAL CAREER OPPORTUNITES” was successfully held on September 24th, 2011. With some consideration, the event was held at Geological Engineering Building First Floor. And all the problems and obstacles until the day before this event took place can be handled very well. This event was attended by 58 participants from 60 targeted participants. Where 23 of whom are member of AAPG, and the remaining 35 people is a student outside the AAPG.
Speakers at this lecture were Mr. Sri Tomo who is Manager Exploration Tropic Energy Pandan LTD and Mr.M.M. Darissaalam who is Senior Geologist Tropic Energy Pandan LTD. Previously the event was opened by head department Geological Engineering UNDIP, Mr. Ir. Dwiyanto, JS.MT
Lecture started with the presentation of basic knowledge about the petroleum system. Where the speaker explains the definition of petroleum systems as a case study of the basin associated with oil and gas as well as all critical elements and processes needed in the formation of oil and gas accumulation. Besides the basic terms in the petroleum system are also described, such as source rock, reservoir rock, overburden, expulsion, and migration.learning hierarchy that must be understood before described as considerable knowledge of the petroleum system, knowledge of hydrocarbon, and the prospect of previous knowledge.
The speaker went on a detailed explanation of the source rock. Where is the four factors to be considered in the source rock is the maturity, type, richness, and expulsion. Then the source rock maturity level expressed by the transformation of organic matter in diagenesis, catagenesis, and metagenesis. One example of a tool to know the thermal maturity is by vitrinite reflectance. And from these tests will be known whether the stage is the source rock is in phase diagenesis, catagenesis, or metagenesis.
The next exposure is related to migration and hydrocarbon traps. Where migration grouped into primary migration (expulsion from source rock) and secondary migration (through carrier beds to trap). While the hydrocarbon trap is divided into structural traps, stratigraphic traps and combination traps. Some examples of images form the hydrocarbon traps are also displayed as an explanation supporting media. And all things related to the reservoir rock is discussed as the last part in a public lecture. This section describes about the problems of permeability and porosity to do with the existence of oil and gas
End of the event, many questions then arise because the stimulation of explanation in the previous session. Enthusiasm of participants seen with many question that lead to knowledge about petroleum systems and its application in fields that once handled by the speaker.
Event closed by the submission of a memento by lecture UNDIP SC, to the speakers, Mr. Sri Tomo and Mr. M.M. Darissalaam.
