KNOC has set a basic strategy to improve on exploration success rate and to make an exploration technology development through an optimal decision based on accurate factors derived from practical data interpretation, which is promising sustainable reserves replacement rate through exploration projects coming forward.
Basin Analysis is one of KNOC’s core E&P technologies. It is a fundamental study of regional geology and its intrinsic petroleum system in the core regions, which contribute to improvement of exploration success rate and reserves replacement rate as well as to the accomplishment of KNOC’s vision. This fundamental study applies geological principles from all the disciplines to structural geology for trapping hydrocarbons, sedimentary depositional processes to insure reservoir presence and geochemical and tectonics interpretation for the origin, maturity and migration pathway modeling of hydrocarbon. It covers not only the above mentioned fields of geology, but also those of seismic and well sequence stratigraphy with other auxiliary data and 2D/3D basin modeling work and so on. Those are the primary essentials to building up successful exploration play fairways and to assessing geological risks and prospectivity which is also a routine data interpretation process.
EPTI supports all the business development units in KNOC and its subsidiaries in geological data evaluation on projects that KNOC takes part in, with those primary essentials and principles. With regional geological understanding, focusing on 4-dimensional (space + time) petroleum system modeling is one of key technology to predict the generation, migration, and quality/quantity of accumulated hydro-carbons, incorporating temperature and pressure calculations through the entire evolutional history of the basin.
Basin analysis and petroleum systems modeling provides the only means to combine all essential elements such as source, reservoir, seal and overburden, and processes of which related to relative timing of trap formation, charge, critical moment, preservation time, to delineate hydrocarbon accumulation and to reduce explorational and operational risks.
