Rosneft contracts 'Hakuryu-5' for Vietnam drilling

Rosneft Vietnam B.V., a company of Rosneft Group, and Japan Drilling Co., Ltd. (“JDC”) represented by its subsidiary Hakuryu 5, Inc. signed an agreement on provision and operation of the marine drilling rig Hakuryu-5, for the purposes of drilling exploration wells within the framework of Rosneft’s projects in Vietnam. It is planned to drill two wells in Blocks 06.1 and 05-3/11 in the Nam Con Son basin offshore Vietnam in 2016. Consistent implementation of drilling works at both blocks will ensure synergy between the two projects and help reduce the timelines for implementation of the works, thus maximizing the efficiency of exploration activities at the Company’s Vietnamese assets. Commenting on the document’s signing, Rosneft Chairman of the Management Board Igor Sechin noted: “We have always welcomed participation of high technology partners from Japan in implementation of the Company’s projects. Despite the difficult macroeconomic situation, today we are expanding our cooperation in the area of exploration and production of hydrocarbons by executing contracts not only in Russia, but also in Asia Pacific.”

Keppel awarded modification contract for 'Hakuryu-5'

Japan Drilling Company (JDC) and Keppel FELS (Keppel) have signed a contract to carry out repair and modification work on JDC’s ‘Hakuryu-5’ semisub drilling rig from April to August 2014. The work will be carried out upon completion of the unit’s contract with Petronas in Malaysia, after which the unit will be mobilised to Singapore. The contract was signed on the 15th January 2014 by representatives of both JDC and Keppel. Both companies have worked together in the past with Keppel previously upgrading the ‘Hakury-10’ rig in 2012.

Angklung Discovery

Salamander Energy plc, the Asia focussed independent oil and gas exploration and production company, announces that the Angklung-1 exploration well in the Bontang PSC, East Kalimantan, Indonesia, has been completed as an oil and gas discovery. Salamander is operator of the Bontang PSC with a 100% interest. The Angklung-1 well was drilled by the Hakuryu-5 semi submersible rig to a total depth (“TD”) of approximately 2,850 metres true vertical depth sub-sea (“TVDSS) and encountered 23 - 27 metres of net gas pay in a high quality Lower Pliocene sandstone unit at 1,850 metres TVDSS. Log evaluation indicates that the formation has porosity of up to 30% and permeability of around 50 millidarcies. A drill stem test was conducted across a 10 metre interval of gas-bearing reservoir which flowed at a surface equipment constrained rate of approximately 24 million standard cubic feet per day. Initial analysis suggests that the gas is dry without any indication of CO2 or H2S. In the deeper section, the well encountered a gross 256 metre section of inter-bedded sandstones and shales of Upper Miocene age. Following petrophysical evaluation of a full suite of wire-line logs, this interval is interpreted to contain a net 120 metres of oil-bearing sandstones. A comprehensive sampling and pressure testing programme recovered samples of light oil and gas, though the sandstones were proved to be tight, having low permeability, and are not considered net pay at this location. The well reached TD in a sequence of Upper Miocene carbonates with strong gas shows. Salamander has acquired more than 650 km2 of 3D seismic in the Bontang PSC over the Angklung structure and surrounding prospects. The Angklung trend extends into the neighbouring SE Sangatta block (Salamander 75%, operator) where a 475 km2 3D seismic survey is currently being acquired. The well has been plugged and abandoned as a discovery. The Group will now conduct further technical work to evaluate both the resource potential of the Angklung discovery and the large inventory of prospects within Salamander’s acreage that exhibit similar seismic attributes to the pay section seen in Angklung-1 well. Work will also be undertaken to further understand the Upper Miocene oil play fairway in the area, highlighted by the Angklung-1 well.

Hakuryu-5 rig on tow to Bontang PSC

Salamander Energy plc, the Asia focussed independent oil and gas exploration and production company, announces that the Hakuryu 5 semi-submersible rig has departed Singapore and is under tow en-route to the Bontang PSC, East Kalimantan, Indonesia. It is expected to take approximately 12 days for the rig to arrive on location. Once on location the rig will be used to drill the Angklung-1 exploration prospect. Angklung is forecast to contain mean prospective resources of 125 MMboe and the well will take approximately 39 days to drill on a dry hole basis.
