Dambus-1 Exploration Well
Salamander Energy plc, the Asia focussed independent oil and gas exploration and production company, announces that the Trident-1X jack up rig has arrived at the Dambus-1 (“Dambus”) location in the Kutai PSC, East Kalimantan, Indonesia and drilling operations have commenced. Salamander holds a 23.4% interest in the Kutai PSC. The Dambus exploration well will be drilled to a depth of approximately 2,700 metres sub sea and is targeting multiple stacked deltaic sandstone reservoirs of Upper Miocene age. The mean gross pre-drill estimate of prospective recoverable resource is c. 130 MMbo and 300 Bcf of gas. The well will be drilled in a water depth of 85 metres and is expected to take approximately 40 days to complete on a dry hole basis. On completion of the Dambus well the rig will move to the Marindan prospect in the south of the Kutai PSC.
Dambus-1 Exploration Well, Kutai PSC, Indonesia
Serica and its partners spudded the Dambus-1 offshore exploration well on 4 September 2010 using the jack-up drilling rig Trident IX. The objective of the well was to investigate the potential for gas and oil accumulations in a stacked sequence of Miocene sands. Dambus-1 was drilled as a deviated well to a total depth of 3,225 metres measured depth ("MD") (2,713 metres true vertical depth subsea ("TVDSS"). Based on the indicative data obtained while drilling, hydrocarbons were encountered in clean sands in the gross interval 2,070-2,102 metres MD (1,787 - 1,812 metres TVDSS) and there were indications of further hydrocarbon-bearing sands in an interval below 2,760 metres MD (2,340 metres TVDSS). In order to obtain definitive data on the extent of the discoveries the well was plugged back and sidetracked and wireline logs, pressure data and fluid samples were acquired. Sidetrack Dambus-1ST was drilled to a total depth of 2,800 metres MD (2,568 metres TVDSS). Excellent quality gas-bearing Miocene reservoir sands were encountered in the interval 2,025-2,047 metres MD (1,795-1,816 metres TVDSS) of which the net gas-bearing sands amounted to approximately 18 metres. Following an extensive logging and sampling programme in Dambus-1ST, the deeper sands were found to be water bearing. The upper gas-bearing sands alone are not expected to be commercially exploitable and the well is therefore being plugged and abandoned. The Trident IX drilling rig will now move to drill the Marindan exploration well, the second well in the present two-well programme in the Kutai PSC.
Mandarin-1 Spud
Salamander Energy plc, the Asia focussed independent oil and gas exploration and production company, announces the spud of the Marindan-1 exploration well in the Kutai PSC, East Kalimantan, Indonesia.

Each rig will have a drilling depth of approximately 30,000 feet.
New rig concept to improve recovery
Statoil is preparing an invitation to tender for a new type of drilling rig for mature fields on the Norwegian continental shelf (NCS). The new rigs, known as category J, will be jack-ups designed by the industry on behalf of Statoil. Statoil will propose for licence groups to take on ownership of these rigs. In order to realise the full potential of the NCS, increasing drilling activity on mature fields is important. Lower rig rates, greater drilling efficiency and access to rigs are key factors to meet this challenge. The new rig concept is designed to meet these requirements. “The key to maintain today’s production level on the NCS towards 2020 is improved recovery from existing fields and fast and effective development of new fields. We need to drill more wells to deliver on our production ambitions,” says Øystein Arvid Håland, head of drilling and well in Statoil. The new category J rigs will be able to operate at water depths from 70 to 150 meters and drill wells down to 10,000 meters. It is a tailor-made jack-up rig for operations in harsh environment on both surface- and subsea wells in the shallow-water segments on the NCS. It will be a tool primarily for drilling and completion of production wells. “Statoil has the capacity and competence to drive technology and innovation to drill more efficiently and rejuvenate the rig fleet on the NCS. The new category J rigs will deliver wells 20% more efficient than conventional rigs. We aim to achieve reduced cost and time per well with safe and efficient operations,” says Håland. The rig design is currently being developed in collaboration with various industry players like hull designers, topside suppliers, construction yards and drilling contractors. “Statoil is continuously working to secure a rig fleet with the right capacities and capabilities to suit our needs. However, upgrade and adaptions on many of the existing rigs appear too costly for our requirements and challenges on the NCS. We are therefore taking steps to rejuvenate the rig fleet and ensure that the right rigs meet the right requirements,” says Jon Arnt Jacobsen, chief procurement officer in Statoil. “Now we follow up our industrial approach by proposing to take ownership of the rigs through licenses to improve economics further. As a long-term industrial player on the NCS, we look forward to working with suppliers who have competence in building and operating rigs to develop new and cost-effective solutions,” says Jacobsen. Statoil plans for invitation to tender for minimum two cat J rigs to be issued in July and for the contracts to be awarded in the 2nd half of 2012. The rigs are to be delivered in the 2nd half of 2015.
