Abstract

This paper deals with the integrated approach by G&G team at the base office and geologists at the well site in tracking down the low resisitivity silty reservoir sands of Middle Bokabil Formation in Well Kalyanpur-1(KP-1) in Dhansiri Valley of Assam & Assam Arakan Basin in the state of Assam, India. The location KP-1 was drilled on a linear structure (upto Bokabil level) formed in the hanging wall fault closure formed against the major down to basin, east hading fault. It is the first well drilled on this prospect with the objective to test the hydrocarbon potentiality of Barail & Bokabil sands. The well fulfilled the target by successfully penetrating Barail and Bokabil section and finally reached basement without encountering the intervening Sylhet Formation due to a major fault passing through this well.
