GAZPROM NEFT TO DRILL AYASHSKY APPRAISAL WELL IN THE SEA OF OKHOTSK

Gazpromneft-Sakhalin, a subsidiary of Gazprom Neft, has signed a contract with Japan Drilling Company, regarding the leasing of a drilling rig for construction of a prospecting and appraisal well at the Ayashsky licence block, located on the continental shelf of the Sea of Okhotsk. The semi-submersible Hakuryu-5-5 is expected to complete all drilling during the 2017 summer season, as well as allowing well testing and core sampling for laboratory testing. Exploratory and appraisal drilling has not, hitherto, been undertaken at the Ayashsky block. The Hakuryu-5-5 floating rig was subject to extensive technological modification in 2014, with further modernisation to be undertaken as part of preparations for the 2017 drilling season in line with the demands of the climatic and hydrological conditions of the Sea of Okhotsk.  (Source and image: Gazprom Neft)
