The Yurihara and Ayukawa oil & gas fields are located in a Yuri plateau 60 km away from Akita city. Japex has been operating in these fields for 25 years. In the future it will be considered to meet with a various problems in these fields such as following points. 1) Decrease of oil production caused by reservoir pressure depletion 2) Increase of water production.
Therefore, technically and economically best methods of artificial lifts had been studied for Yurihara SK-16DH well. As a result, Japex had decided to give a field test of hydraulic jet pump (JP)+coiled tubing (CT) system for the first time. This system has advantage of easy operation and unnecessity of workover. And so Japex carried out some test of JP + CT system in 2006 and 2008. In consequence of the test, Japex has confirmed oil recovery enhancement and stability of oil/gas production.
