Identification of small and large hydrocarbon structures in the region

Preparation of Strategic Management and Development Plan (SMDP) and prioritization of identified exploration blocks.

Studying and assessment of on-shore hydrocarbon potentials by: 

o Geological field studies
o Surface sampling
o Study of tectonic and the creation and evolution of mud-volcanoes in the area
o Study of oil and gas reserves
o Identifying the potential of source and reservoir rocks by available data
o Detailed study of Sepid-Rud river sediments
o Interpretation of shoreline 2D seismic data and the study of on-shore Geomagnetic and Gravity data


Available data collected from on-shore wells and the information were analyzed and correlated

KEPCO amid many other companies is a subdivision of National Iranian Oil Company (NIOC) founded in January 1998. KEPCO is an authority in exploration, development and production of oil and gas in Iran concerning South Caspian Sea and three littoral provinces of Golestan, Mazanderan and Gilan in Iran. KEPCO supervises all the contracts signed by local and international companies regarding exploration and development of hydrocarbon reserves in the area including the pertinent environmental matters. KEPCO is committed to the development of Caspian Sea oil and gas reserves as well.
